PREFACE. 
 
 This essay on Theine originally appeared in 
 the Polyclinic, from September, 1887, to Feb- 
 ruary, 1888 ; and in order to give the research 
 which has been made of this drug a more per- 
 manent place in medical literature, it was 
 deemed proper to publish it in a separate little 
 volume. 
 
 Herewith I desire to express my warmest 
 thanks to those of my medical friends who 
 have been kind enough to report to me the 
 results which they obtained in the clinical em- 
 ployment of theine ; for I feel that the practical 
 value which this investigation possesses is chiefly 
 due to this part of the contribution.

INTRODUCTION. 
 
 CHAPTER I. 
 THEINE 
 The tea-plant, from which theine is obtained, 
 is a shrub from twenty to thirty feet high, and 
 is indigenous to the southern part of Asia, but 
 is extensively cultivated in China, Japan, and in 
 South America, as well as to a small extent in 
 the United States. Its use as a beverage dates 
 from a very early period in Chinese history, but 
 the Greeks and Romans were ignorant of its 
 existence, and it was only introduced into Eu- 
 rope about the year 1657. The botanical origin 
 of tea is Thea Bohea, T. viridis, T. sinensis, 
 and T. assamica, and a few hybrids ; and the 
 many varieties of tea in the market are prepared 
 by selecting young or old leaves, and subjecting 
 them to various processes of treatment. Tea

lO HISTORY OF THEINE 
 
 was probably first used for medicinal purposes. 
 It is a common custom of our own day to apply 
 tea leaves for the purpose of reducing inflamma- 
 tion and allaying pain. 
 
 Theine, to which tea principally owes its vir- 
 tues, is an alkaloid, and was first found in the 
 leaves of Chinese tea by Oudry, in 1827. This 
 discovery was confirmed by Miilder and Jobst, 
 in 1838, who believed it to be identical with 
 caffeine and guaranine. Its chemical formula 
 is CgHioN^Og, and it is known as trimethyl- 
 xanthine. It occurs in snow-white, needle- 
 like crystals, is almost tasteless, but produces a 
 slight tingling on the end of the tongue, which 
 is immediately followed by a temporary local 
 anaesthesia. It is soluble in fifty parts of cold, 
 but more soluble in warm water. 
 
CHAPTER II. 
 THE PHYSIOLOGICAL ACTION OF THEINE 
 
 My first experiments with theine were made 
 in the spring and summer of 1885, and were 
 pubhshed in the Therapeutic Gazette for Sep- 
 tember, 1885, under the title of The Physiologi- 
 cal and Therapeutic Actioji of Caffeine, Theine, 
 and Guaranine. At this time I was ignorant of 
 the fact that theine, caffeine, and guaranine 
 were manufactured indiscriminately from coffee, 
 tea, kola nut, Paraguay tea and guarana ; and 
 that they were all sold out of the same bottle 
 and labeled according to the demands of the 
 trade ; but I supposed that I was using theine 
 made from tea leaves, and caffeine from coffee 
 beans. Inquiry, however, soon undeceived 
 me afid demonstrated very positively that nearly 
 all of that which is sold under the name of caf- 
 feine at present is not caffeine at all, but theine, 
 II 
 
12 PHYSIOLOGICAL ACTION 
 
 since it so happens that it is cheaper to manu- 
 facture the alkaloid out of tea leaves than from 
 any of the other raw materials. Moreover, it 
 was further found that very little, if any, theine 
 or caffeine is manufactured in this country, and 
 that these agents are principally imported from 
 Europe. 
 
 Of course, under these circumstances, it was 
 quite evident that the article which I used for 
 theine must have emanated from tea, but on 
 account of the uncertain nature of that which I 
 used for caffeine I determined to review all my 
 previous work on this subject. That I used two 
 different agents was quite certain, for I could not 
 have obtained the varying results in my experi- 
 ments which I did if they had been alike in 
 composition. Therefore Mr. William C. Harris, 
 then with Messrs. Henry C. Blair's Sons, kindly 
 undertook to manufacture both alkaloids for 
 me from tea and coffee, respectively, and 
 quite recently I also received the same alkaloids, 
 made from the same sources, from Merck, of 
 
OF THEINE 13 
 
 Darmstadt, who, since my second series of ex- 
 periments, has informed me that he will in the 
 future manufacture these alkaloids separately — 
 hence in ordering from him it is necessary to 
 specify the alkaloid which is wanted. I fully 
 reviewed my former work, and the net result 
 confirms the conclusions drawn from the first 
 series, and I have even found reason for believ- 
 ing that the difference between the action of the 
 two alkaloids in regard to sensation is greater 
 than my earlier experiments indicated. 
 
 The gross effects of tea and coffee on the 
 animal economy have always been regarded 
 as dissimilar, but their alkaloids have, until 
 quite recently, been universally considered 
 identical in their action. The supposed iden- 
 tity of action of the two latter agents can only 
 be explained on the score that, after once 
 having been shown that they are chemically 
 alike, the assumption naturally followed that 
 they must also be alike in their physiological 
 action. This view of their supposed identity 
 
14 PHYSIOLOGICAL ACTION 
 
 of action has also been encouraged by Aubert, 
 Albers, Amory, Bennett, McKendrick, Burnett 
 and others who investigated the drugs experi- 
 mentally, although Leven, as far back as 1868, 
 showed that theine produced convulsions in 
 frogs while caffeine did not ; and that the 
 lethal dose of theine was larger than that 
 of caffeine. One important reason why the 
 results of Leven differ so materially from those 
 derived by others lies in the fact that he used 
 the genuine alkaloids produced separately 
 from tea and coffee, which does not appear 
 to have been the case with the other experi- 
 menters. Moreover, in view of the fact that 
 the effects of theine and caffeine were believed 
 to be the same, it is very difficult to obtain 
 evidence as to the action of either agent. Toxi- 
 cologically, we know more about caffeine than 
 we do about theine, for, since coffee is much 
 more powerful than tea, it has occasionally 
 been employed for criminal purposes. 
 
 A detailed account of the large number of 
 
OF THEINE 15 
 
 experiments which I made with these agents 
 will not be given here, since they would swell 
 this little work to undue dimensions ; but their 
 condensed results, which appear below, demon- 
 strate that, while the actions of theine and 
 caffeine agree in many respects, they also dis- 
 agree in some important particulars. They 
 both first affect the anterior extremities of 
 frogs, and both diminish respiration and cause 
 hyperaesthesia during the latter stage of the 
 poisoning process, although the supersensitive- 
 ness is much more marked in theine than in 
 caffeine. They differ in the following respects : 
 Theine principally affects sensation, while caf- 
 feine does not ; theine produces spontaneous 
 spasms and convulsions, while caffeine does 
 not until very late in the stage of poisoning ; 
 theine impairs the nasal reflex early in the 
 poisoning process, while caffeine does not, if at 
 all, until the very last stage ; the lethal dose of 
 theine is larger than that of caffeine. 
 
 The differences in the action of these two 
 
l6 PHYSIOLOGICAL ACTION 
 
 agents as here indicated will, I think, be suffi- 
 cient to convince even the most skeptical that 
 theine and caffeine can no longer be regarded 
 as identical, so far as their physiological action 
 on the frog is concerned. In order to show to 
 myself, as well as to others, that there is a de- 
 cided difference between the two preparations, 
 and that I did not practice any unconscious 
 self-deception, I frequently tested the contents 
 of two numbered vials, one of which contained 
 theine and the other caffeine, but which were 
 only known to me by their numbers, and could, 
 without difficulty, always designate the true 
 nature of each specimen after testing its action 
 on the frog. This is, certainly, a crucial ex- 
 periment which demonstrates very clearly that 
 the toxicological tests of experimental physi- 
 ology are more accurate and delicate than those 
 of physics and chemistry combined. 
 
 The argument which has been advanced 
 against my deductions that the theine and 
 caffeine employed by me were probably not 
 
OF THEINE 17 
 
 chemically pure, must, I think, fall to the 
 ground, when it is taken into consideration that 
 precisely identical results were obtained from 
 two separate manufactures of both alkaloids by 
 Merck, of Darmstadt, against neither of which 
 the charge of impurity can be brought. In the 
 early part of my experimental review I did use 
 preparations of both which were not altogether 
 free from the coloring matter of the raw ma- 
 terial, but they gave rise to the same differences 
 as those which were brought out subsequently 
 by the purer specimens. However, if the ob- 
 jection of impurity be still urged, it devolves 
 on those who make it to manufacture such 
 specimens of both alkaloids which will satisfy 
 their ideal of purity, and have them subjected 
 to a proper test for the purpose of finding out 
 whether they fail to give a differential physio- 
 logical reaction. 
 
 The power of theine to produce such decided 
 and complete sensory paralysis in the lower 
 animals led me to test its physiological prop- 
 
PHYSIOLOGICAL ACTION 
 
 erties on the healthy human being, and, with 
 this end in view, I introduced moderate, or 
 probably small, doses of the drug hypoderm- 
 ically in a nuijiber of instances, and noted the 
 results. 
 
 In the main, there was a general agreement 
 in the symptoms which developed, and hence 
 only one case, typical of the rest, will be given 
 here. The drug was injected into the left fore- 
 arm of an adult in good health, whose same arm, 
 however, was fatigued by carrying a satchel to 
 the railroad station on the previous morning.

 6.40. Sensation more normal in forearm. Fin-

 The physiological action of theine on man, as 
 brought out in this as well as in a number of other 
 observations under my care, may be summed 
 up as follows : Dose from one-fifth to half a 
 grain. Numbness of arm and hand below seat 
 of injection — " a feeling as if the hand had 
 been steeped in a solution of carbolic acid," as 
 one of the subjects of experimentation expressed 
 it. A feeling of coldness and an occasional 
 disturbance of temperature in the member under 
 its influence. A slight reduction in the pulse 
 rate, and no intoxication of the brain. No im- 
 pairment of motion. The anaesthesia shows 
 itself in a very few minutes, and is much more 
 marked in some individuals than in others. A 
 
OF THEINE 21 
 
 relief to the feeling of fatigue. The tempera- 
 ture disturbance was not regular. Out of four 
 cases in which the temperature was taken, it 
 showed no difference in one, and in another 
 one the uninjected hand was slightly higher 
 (0.4° Fahr.) in temperature than the injected 
 one. In two there was quite a marked fall in 
 temperature — one 0.8° Fahr. and the other 1.2° 
 Fahr. lower in the hand of the injected than in 
 that of the uninjected arm. And, strange to 
 say, the hand which showed the greatest de- 
 pression in temperature experienced the least 
 degree of anaesthesia. A certain feeling of 
 coldness always accompanies the numbness 
 produced by theine, yet, in my earlier observa- 
 tions, I repeatedly failed to detect any ther- 
 mometric differences. 
 
 Dr. C. H. Castle, of Cincinnati, Ohio, was in- 
 duced to test the action of theine by the appear- 
 ance of my first article on this subject.^ The 
 
 * The Therapeutic Action of Theine; a New Analgesic.

22 PHYSIOLOGICAL ACTION 
 
 results of his experiments, which were both of a 
 physiological and chemical nature, were read 
 before the Cincinnati Medical Society, and pub- 
 lished in The Cincinnati Lancet and Clinic for 
 February 6th, 1886, and since they were made 
 with pure theine, extracted by his own chemist, 
 and because they add some hitherto unobserved 
 features in the action of the drug, they are ex- 
 tremely interesting and instructive. He made, 
 in all, three physiological experiments on him- 
 self, of which he says : — 
 
 " The first time I injected one-sixth of a grain 
 into my left forearm, immediately below the 
 flexure of the elbow joint. I will not weary you 
 with the details of the observations as made at 
 intervals of a few minutes. The noticeable 
 effect was remarkably rapid. An angry blush 
 and swelling spread from the point of injection, 
 but what looked like a most delicately ten- 
 der spot was singularly devoid of sensation. 
 It was not, nor did it become, totally 
 anaesthetic, but in what appeared to be 
 
OF THEINE 
 
 an inflamed area of sensibility was markedly 
 dulled. Presently a numbness, such as we feel 
 when a member is beginning to 'go to sleep,' 
 from pressure upon its supplying nerves, stole 
 over my wrist and hand. Little tinglings, 
 scarcely noticeable had not one been on the 
 watch for strange manifestations, came and 
 went in various places. At no time was motility 
 impaired. The temperature of the left hand, 
 and I beg to call your attention to this point, 
 was markedly lowered. The effects of the 
 injection lasted about two hours. 
 
 " The second injection was made under 
 somewhat different circumstances. I had rather 
 severely bruised my right hand, and the pain 
 on pressure over the metacarpal bone was quite 
 severe. I therefore injected one-third grain of 
 theine subcutaneously over the ulnar nerve 
 just below the elbow. 
 
 ** The same phenomena were noticed as in 
 the first use of the alkaloid — sensibility around 
 the injection was markedly diminished, lower 
 
24 PHYSIOLOGICAL ACTION 
 
 down the forearm and in the wrist and hand 
 less markedly so ; the right hand lost as much 
 in temperature as had the left hand previously, 
 but I am compelled to say that I was disap- 
 pointed in the analgesic effect that I had 
 expected. The extreme sensibility was dulled, 
 to be sure, and my hand no longer hurt when 
 I put it into my overcoat pocket, as it had be- 
 fore, but any deep pressure instantly informed 
 me that the nerves about the joint still resented 
 the impact of a foreign body with the surface. 
 
 " The third observation was made again 
 upon the left arm ; this time one-half of a grain 
 was used, and though an accident, perhaps, 
 somewhat marred the experiment, some points 
 were brought out more prominently. The in- 
 jection, made for me by a friend, was a deep 
 one — intermuscular — and the withdrawal of the 
 needle was followed by a slight hemorrhage, 
 sufficient to raise a conical subcutaneous tumor 
 of a diameter of a one-cent piece. Instantly 
 there was a deep-seated pain, probably due, I 
 
OF THEINE 25 
 
 thought, to extravasation from the wounded 
 vessels into the intermuscular planes. Full ex- 
 tension was impossible ; partial extension very 
 painful ; the painful seats being deeply under 
 the point of injection and the dorsal aspect of 
 the metacarpo-phalangeal points. 
 
 " As in former observations, sensibility was 
 affected almost immediately, and in three 
 minutes the left hand was blanched and al- 
 most cold to the touch. My pulse was always 
 full, strong, and but slightly more frequent 
 than normal. Very soon peculiar constitutional 
 disturbances appeared, and not entirely like 
 those described in the standard works on ma- 
 teria medica. I was excited and talkative, and 
 so rapidly did I talk that I would soon exhaust 
 a subject broached by others, and endeavor to 
 introduce some natural descendant of the idea 
 as a topic of conversation, apparently so far 
 ahead of its proper sequence in a well-ordered 
 train of thought as to appear like an interrup- 
 tion with an irrelevant subject. Failing to 
 
26 PHYSIOLOGICAL ACTION 
 
 gain a hearing, as I frequently did, I would in- 
 dulge in snatches of song or broken ejaculations 
 which had a world of meaning in them then, 
 but which, as I look back upon them now, 
 seem utterly absurd. 
 
 "Alternating with states of great bodily ac- 
 tivity were spells almost of a fainting character. 
 These were seven or eight in number, and 
 beginning soon after the injection, gradually 
 ceased after the lapse of six or seven hours." 
 
 This vivid description of the effects of theine, 
 as Dr. Castle observed them on himself, is 
 very instructive, and in some respects new. 
 The psychic disturbance which he experienced 
 I have never observed, although I have admin- 
 istered five times the quantity he employed ; 
 and the only way in which I can account for his 
 cerebral intoxication is on the score that the deep 
 injections which he practiced chanced to in- 
 troduce the theine directly into a blood vessel, 
 and it was at once carried to the brain and pro- 
 duced the hallucinations as described. This 
 
OF THEINE 27 
 
 is all the more probable because the central 
 disturbance manifested itself directly after the 
 injection, which, ordinarily, should not have 
 appeared until in a later stage of the poisoning 
 process. 
 
 From these experiments, and from those 
 which were made on the frog, I think the follow- 
 ing conclusions may be legitimately drawn 
 concerning the physiological action of theine on 
 man : — 
 
 1. It has a special affinity for the nerves of 
 
 sensation. 
 
 2. It produces anaesthesia when administered 
 
 subcutaneously. 
 
 3. Its anaesthetic action is confined below the 
 
 seat of its injection, /. <?., its influence ex- 
 tends from the centre to the periphery, 
 and not in the opposite direction. 
 
CHAPTER III. 
 
 THE SPECIAL THERAPEUTIC INDICATIONS FOR 
 THE USE OF THEINE 
 
 From its physiological action it is quite ob- 
 vious that in theine we possess an agent which 
 has the power of paralyzing sensation without 
 affecting motion, and that it does this with a 
 great degree of certainty and without any appre- 
 ciable injury to any part of the body, even when 
 administered in large doses. It now remains 
 for clinical medicine to demonstrate and to 
 establish how far this analgesic property can 
 be utilized, and with this purpose in view the 
 greater portion of the following pages will be 
 devoted to the task of pointing out the special 
 pathological conditions and to that of the cita- 
 tion of cases in which the drug is indicated. 
 
 In order to obtain the full effect of theine, it 
 is not necessary to inject it deeper than imme- 
 diately beneath the skin. Of deep injections I 
 29 
 
30 THERAPEUTIC INDICATIONS 
 
 am not able to speak intelligently, since I was 
 always satisfied with the results which are 
 derived from superficial injections. Dr. Castle, 
 in the article already referred to, relates his own 
 personal experience with one deep injection, in 
 which the drug certainly exerted a marked 
 influence on the brain, owing, probably as has 
 already been stated, to the fact that the whole 
 dose found direct entrance into the circulation, 
 and was at once carried to the great nerve 
 centres. 
 
 Again, theine, as a rule, is surprisingly 
 prompt in exerting its analgesic action. I have, 
 on a large number of occasions, witnessed pa- 
 tients who had too much pain to move an 
 arm, or who were too stiff to stand erect, swing 
 their arms and straighten their bodies in less 
 than five minutes after its introduction. It is 
 not always so prompt, but this is probably due 
 to the smallness of the dose. I have seen cases 
 where no benefit had been derived from one- 
 third of a grain, which, on the dose being 
 
FOR THEINE 3 1 
 
 doubled, improved at once. Therefore, when 
 a single dose fails to act favorably, it is always 
 advisable to increase, even if this has to be 
 done to a large extent. I have repeatedly 
 injected as much as two and one-half grains 
 without experiencing anything except the 
 best results, I would not hesitate to go 
 even beyond this limit. To one patient who 
 was suffering from the most intense neuralgia 
 of both lumbo-sacral and left cervico-brachial 
 plexuses, which was accompanied by sleepless- 
 ness, spasm of the muscles of both legs and of 
 those of the left arm, I gave two and one -half 
 grains of theine subcutaneouslyin four different 
 localities along the spine, with instantaneous 
 relief to the pain, and the induction of sleep 
 during the following night. This amount was 
 injected daily for twenty-one days in succession, 
 at the end of which time he was almost entirely 
 free from pain, improved in appetite and in 
 sleep, and felt better in every way. In another 
 case of locomotor ataxia, I injected three grains 
 
32 THERAPEUTIC INDICATIONS 
 
 of theine in different spots along the spine 
 every other day, chiefly for the purpose of 
 relieving the pain and contractions in the ex- 
 tremities, as well as the constriction around the 
 base of the chest. It removed all these diffi- 
 culties at once, and made the patient feel more 
 comfortable than before. Another feature which 
 recommends theine to favor is its prolonged 
 influence. After pain has once been relieved 
 by it, it is very rare to find the same returning 
 inside of ten or twelve hours, and oftener 
 not until in twenty-four hours, and then, in all 
 probability, not in its original intensity. I am 
 referring now to obstinate cases of pain. Where 
 the pain is more unstable, it is not rare to find 
 that one or two injections relieve it perma- 
 nently. 
 
 No prolonged irritation and no inflammation 
 have ever been produced during my experience 
 at the seat of its injection. It gives rise to some 
 burning at first, which disappears in the course 
 of a very few minutes, and is replaced by a 
 
FOR THEINE 33 
 
 marked area of anaesthesia. Most of the burn- 
 ing is undoubtedly due to the comparatively 
 large amount of water which is necessary to 
 dissolve a drug of a solubility as low as that of 
 theine. When it is prepared with benzoate of 
 soda its solubility is markedly increased, and* I 
 have therefore used it for more than a year 
 according to the following formula : — *

 Sodium chloride, gr. viij 
 
 Distilled water, flgj. M. 
 
 SiG. — For hypodermatic use. Six minims equal 
 one-half grain of theine. 
 
 Finally, in regard to the employment of a 
 particular kind of theine, I would say that every- 
 thing which at present falls within the commer- 
 cial description of both drugs is principally 
 made up of theine ; hence, very good clinical 
 results are obtained from that which is found in

 Mr. J, A. Kyner, pharmacist of the Phila. Polyclinic. Also 
 by Mr. William C. Harris, 23CI and Spruce Sts., Philadelphia, 
 
34 THERAPEUTIC INDICATIONS 
 
 the market, although it is very obvious, from 
 my experimental deductions in regard to the 
 differential action of theine and caffeine, that 
 the best results are obtained from the genuine 
 article, which is now manufactured and fur- 
 nished by Merck, of Darmstadt, Germany, and 
 which I altogether employ at the present time. 
 In order to avoid annoyance and disappoint- 
 ment, it is highly important to constantly bear 
 in mind the pathological conditions which only 
 are amenable to the influence of theine. It 
 must be borne in mind, first of all, that its 
 function is solely that of pain-relieving ; and 
 while it performs this office to perfect satisfac- 
 tion, it also fails to give permanent relief to 
 obstinate and protracted pain, unless it is aided 
 by remedies which tend to improve the nutri- 
 tive state of the affected nerves, or which are 
 capable of removing the diatheses upon which 
 the painful affections depend. A neglect of 
 this simple rule frequently led to failures in my 
 earlier employment of the drug. Therefore the 
 
FOR THEINE 35 
 
 burden of what follows in this essay will be 
 devoted to a consideration of the relation be- 
 tween the action of theine and neuralgia, as 
 well as that between its action and other kinds 
 of pain which are generally associated with 
 various constitutional conditions, like malaria, 
 anaemia, simple chronic rheumatism, chronic 
 gonorrhceal rheumatism, gout, etc. ; and in 
 connection with the theine treatment, the im- 
 portance of appropriate auxiliary medication 
 in each special condition will be fully discussed. 
 
 THE DIFFERENTIAL ACTION BETWEEN THEINE 
 AND MORPHINE. 
 
 Morphine enjoys the distinction of being the 
 favorite analgesic of the medical profession, and 
 there can be no doubt that it fairly merits this 
 position. The physiological action of morphine, 
 however, differs widely from that of theine. It 
 produces its analgesia by primarily affecting 
 the cerebral centres, although the experiments 
 of Eulenberg, Falk and others show that it 
 causes a certain degree of local anaesthesia at 
 
36 THERAPEUTIC INDICATIONS 
 
 the seat of injection. But in order to manifest its 
 characteristic action, which is central and not 
 local, it must be carried to the cerebrum by 
 the circulation, and make its impress there, 
 while theine, as we have seen, has a local action, 
 which is entirely independent of the great nerve 
 centres. The peripheral action of theine seems 
 to be confined altogether below the seat of its 
 injection, although there can be no doubt of its 
 general absorption by the blood and of its 
 distribution throughout the whole body. The 
 feelings of patients and of persons on whom I 
 have made physiological experiments invari- 
 ably attest the fact that the brain is exempt from 
 any narcotic impression, and that its perceptible 
 action is wholly confined to a point below its 
 introduction, in which region they feel a sense 
 of tingling and of numbness. This localized 
 influence brings out one of the great therapeutic 
 advantages which theine possesses over mor- 
 phine and over all other agents of this class. 
 By operating only on the peripheral portion of 
 
FOR THEINE yj 
 
 the trunk of a nerve and of its ramifications, it 
 leaves the higher nerve centres intact, and hence 
 does not bring about the undesirable central 
 intoxication which almost always follows a full 
 dose of morphine. 
 
 It is very clear, then, that the spheres of action 
 of morphine and of theine are entirely different, 
 and that each one must be prescribed in suit- 
 able conditions, and in order to achieve this 
 practical end the following rule may be 
 suggested : When it is necessary to narcotize 
 the centres of innervation in order to relieve a 
 given pain, then morphine is indicated ; but 
 when it is not necessary to do this, then theine 
 will accomplish the work safer, better and more 
 promptly than morphine. On general principles 
 it may, therefore, be stated, that morphine 
 gives the best results in acute pain, while theine 
 is most beneficial in chronic affections of the 
 sensory nerves. 
 
CHAPTER IV. 
 
 NEURALGIA 
 
 Neuralgia is preeminently a painful disease. 
 It is, in most instances, a unilateral and an 
 intermittent affection, and manifests itself in 
 tender spots, which mark the superficial exit of 
 the affected nerves. It is generally looked upon 
 as a functional disease ; but there can be no 
 doubt that the condition which answers to the 
 symptom of pain is one in which there is a 
 morbid constitutional change of the nerve 
 giving rise to it, although there is no evidence 
 of any such change to our unaided senses. 
 Furthermore, there can be no doubt that in all 
 cases of neuralgia either the general or local 
 condition of the sufferer at the beginning and 
 during the attack is one of anemia, depression 
 and debility. The affected nerve is impaired in 
 its nutrition, and hence its vitality sinks below 
 that standard which constitutes 7ierve health. 
 
 38 
 
NEURALGIA 39 
 
 The subjective expression of this exhausted 
 state is one of pain, which Valleix defines as 
 the cry of a hungry nerve. 
 
 Neuralgia is generally of malarial and some- 
 times of rheumatic origin, but is also frequently 
 associated with certain periods and conditions 
 of life in which the malarial and rheumatic 
 elements may be entirely wanting. Thus, it 
 occurs in the middle period of life, when the 
 body is most exposed to severe and protracted 
 labor, to child-bearing, etc., as well as during the 
 period of bodily decay, when senile degenera- 
 tions are prone to set in. Then, again, it also 
 manifests itself in states of malnutrition, anae- 
 mia, etc. Topographically, neuralgia may be 
 divided into several local varieties, the chief of 
 which are the sciatic, crural, intercostal, dorsal, 
 cervico-brachial, cervico-occipital and trigem- 
 inal — given here, probably, in the order of 
 frequency with which they meet the eye of the 
 practitioner. Cases of each of the above-named 
 varieties, which were treated with theine, will 
 
40 SCIATICA 
 
 be given in their appropriate places, as well as 
 their additional treatment.^ 
 
 SCIATICA. 
 
 Case i. — Mrs. A.; aged 49 years; came under 
 my care May 2d, 1885, when she had constant 
 pain in right leg from hip to foot, ever since the 
 preceding Christmas. The pain followed the 
 course of the nerves of the leg, and, of course, 
 was very much aggravated by walking. The 
 leg was considerably atrophied and was weak 
 and uncertain in its gait. Her appetite was 
 poor and bowels irregular, and she passed 
 whole nights without sleep, on account of pain. 
 
 * The additional treatment, unless otherwise stated, fre- 
 quently consisted in the administration of two mixtures, which I 
 found very useful, the formulae for which will be reproduced 
 here ; and in order to save space and repetition, they will be re- 
 ferred to in the following pages as the quinine and ammonia 
 and the sodium salicylate mixtures, respectively : —

SCIATICA 41 
 
 She was anaemic, and had been treated with 
 iron, quinine, ammonia, sodium sahcylate, 
 potassium iodide, atropine, morphine, poul- 
 tices, blisters, etc., without avail, until the fol- 
 lowing 1 8th of July, when I injected one-fifth 
 grain of theine into the calf of her leg. The 
 pain ceased in less than five minutes, and never 
 returned in its original force. In half an hour 
 her heel and foot began to feel numb and 
 insensible, which lasted for about twelve hours, 
 but her mind was perfectly free from its influ- 
 ence. She experienced no headache or drowsi- 
 ness. 
 
 July 20th. Pain in whole leg better since last 
 injection, but has not entirely disappeared from 
 the thigh, so I introduced one-fifth grain into 
 the latter region. 
 
 28th. Leg altogether free from pain, but still 
 complains of some in foot ; otherwise she is 
 improving. Injected one-fifth grain over instep. 
 
 Sept. 6th. Feels better. Slight pain around 
 ankle joint. Injected one-tenth grain at this 
 
42 SCIATICA 
 
 point. This was the last injection she received, 
 and she made an uninterrupted recovery. 
 
 Case ii. — B.; aged 50; carpenter; was first 
 seen April 3d, 1886, when he complained of a 
 severe pain for nearly two years in lumbar 
 region, radiating down both legs. He is stiff in 
 both legs and in the back, and rises from a 
 chair with great difficulty. He had malaria, 
 but gives no specific or rheumatic history. In- 
 jected half-grain doses of theine on each side of 
 the sacrum, and two doses of similar strength 
 near the trochanters on both sides. He said it 
 relieved the pain and stiffness at once, and that 
 he was as able as ever to get up from a chair. 
 
 April 6th. Says he is better, but still has some 
 pain. Repeated the injections and internally 
 gave him the quinine and ammonia mixture. 
 
 April loth. Pain nearly all out of back, legs feel 
 somewhat stiff. Two injections near the trochan- 
 ters on both sides. Same internal treatment. 
 This patient continued to improve, and was 
 entirely well by end of same month. 
 
SCIATICA 43 
 
 Case hi. — S. M.; aged 49 ; came under my 
 treatment March 25th, 1886, when she com- 
 plained of pain in right hip, which extended 
 down the Hmb of the same side. Impairment 
 of motion and stiffness in same leg. Had 
 malaria. At her first visit gave her quinine 
 and ammonia mixture only. The next day, the 
 26th, she returned and reported that the pain 
 was no better, and that it extended as far as the 
 ankle joint. She said that she had a feeling as 
 if a lump of ice were lying against her foot all 
 the time. Injected half a grain of theine in 
 right hip near the great trochanter. 
 
 April 1st. Some improvement — walks much 
 better. Another injection of theine and same 
 internal treatment. 
 
 April 3d. Pain all gone except below the knee ; 
 another injection. 
 
 April 4th. Coldness in foot has disappeared 
 and is almost entirely free from pain. Another 
 injection. She continued to improve. 
 
44 SCIATICA 
 
 Case iv. — C. P. ; aged 48 ; had pain in right 
 hip joint on April 20th, 1886, which followed 
 the course of the sciatic nerve on same side. 
 Stoops with great difficulty. Had rheumatism. 
 Injected half a grain of theine over painful spot 
 in hip joint, which relieved him at once. Could 
 stoop without pain after injection. Never saw 
 him again. 
 
 Case v. — L. M.; aged 60; came to me, April 
 22d, 1886, complaining of severe pain in sacral 
 region, which radiated down both extremities as 
 far as the knees. Injected half a grain on each 
 side of sacrum, and she expressed herself much 
 relieved immediately after the injection. Inter- 
 nally, she received the quinine and ammonia 
 mixture. 
 
 April 24th. Better. Pain in sacral region 
 almost gone, and she could walk better than 
 before. Injected half a grain in the fleshy part 
 of each leg. 
 
 April 27th. No pain in back. Did a heavy 
 day's washing without producing any pain in 
 
SCIATICA 45 
 
 back since her last visit. This she had not 
 been able to do for a long time. The only pain 
 she complains of now is in her left leg from 
 knee to ankle joint. Injected half a grain above 
 the knee. The pain disappeared at once. With 
 the same internal treatment, and an occasional 
 injection, she continued to do well. 
 
 Case vi. — E.; aged 35 ; came under observa- 
 tion June 20th, 1887, when he gave the follow- 
 'ng history : Pain along both sciatic nerves 
 during the last three years. The attacks of 
 pain come on simultaneously in both nerves, 
 although the left leg is the worst. Some loss 
 of motor power in this leg. Has had malaria 
 and rheumatism, some burning in soles of feet. 
 Injected half a grain of theine in each buttock 
 over the course of the sciatic nerves. Internally, 
 gave him the quinine and ammonia and soda 
 salicylate mixtures, in alternation every three 
 hours. 
 
 June 2 1 St. Pain better last night than it has 
 been for a long time. Slept well, which he had 
 
46 SCIATICA 
 
 not done for several nights. Gave him two 
 more injections in same regions, and continued 
 same internal treatment. The pain at no time 
 became bad again, and in less than a month of 
 the treatment outlined above he ' was entirely 
 free from pain, could sleep well, had regained 
 the want of power in his left leg, and he was 
 able to resume his vocation. 
 
 The following three cases were reported to 
 me by Dr. H. C. Fegley, of Ashland, Pennsyl- 
 vania, who writes : — 
 
 " Since your article on the action of theine 
 was published, I have had the opportunity of 
 testing its analgesic effects in three very aggra- 
 vated cases of sciatica. In two cases complete 
 recovery, with the exception of slight stiffness 
 of the leg in one, took place. The third was 
 an aggravated case of three years' standing, and, 
 although not cured, was so much benefited that 
 she is able to attend to her household duties." 
 
 Case vii. — S. ; December 20th, 1885 ; had 
 been unable to leave her chair, in which I found 
 
SCIATICA 47 
 
 her, for two weeks, the least movement causing 
 the utmost agony in the whole left leg. When 
 perfectly quiet, no pain was felt except occa- 
 sional sharp twinges shooting down to the 
 foot. I put her to bed and injected a quarter 
 of a grain of Merck's theine into the thigh about 
 the seat of greatest pain. The injection caused 
 intense burning, which lasted about three 
 minutes, when she said it had left her and that 
 movement in her limb caused less pain. The 
 following evening I injected half a grain ; and 
 repeated the dose a day after, when she felt, as 
 she expressed it, entirely cured. 
 
 Case VIII. — H. ; January loth, 1886; com- 
 plained of intense, deep-seated pain in the leg, 
 which had been coming on gradually for nearly 
 a week. She never had sciatica before, and 
 two injections, of three-quarters of a grain each, 
 relieved her entirely. 
 
 Case ix. — Mrs. A. ; has been a sufferer for 
 nearly three years, and has tried a great many 
 remedies, with little or no benefit. Theine in 
 
SCIATICA 
 
 doses of a fifth of a grain relieved her only for 
 three or four hours, but three-quarter grain doses 
 gave her a full night's rest. The intense sciatic 
 pain, she says, has passed away, but there are 
 still some soreness and considerable stiffness in 
 the limb. 
 
 Dr. S. reports his own case to me under date 
 of December 21st, 1885, in the following lan- 
 guage :— 
 
 Case x. — '' Dear Sir : I have just this day 
 read your article on the * Therapeutic Action of 
 Theine, ' and would say that my own case is 
 almost a fac-siinile of your case Mrs. A. A. 
 (which was a case of sciatica). I have tried 
 every remedy I could think of, but have found 
 nothing to give relief but injections of morphine. 
 1 had to give up the morphine on account of the 
 constitutional effect which it brought on. My 
 trouble was caused by being thrown from my 
 cutter about a year ago, but had no severe 
 pain until last August, when I became a 
 subject of severe blood-poisoning, contracted 
 
SCIATICA 49 
 
 during an operation, and from which time the 
 pain in my hmb began to be terrible. I went 
 to the springs (Saratoga) and continued treat- 
 ment for the poison. I feel so badly now that 
 I find it impossible to write you in full. If you 
 will be kind enough to send me some theine, 
 with instructions how to use it, I will test it and 
 have my case carefully reported to you. I 
 would further state, that I returned from the 
 springs about three weeks ago, but received no 
 benefit. I am now, and have been, in bed for 
 the past ten days, and I only hope that this new 
 remedy will give me some relief from the most 
 terrible pain possible to endure." 
 
 Under date of March 22d, 1886, Dr. S. states : 
 "In relation to the theine, I will say that it has 
 done its work for me. The first injection was 
 made on December 25th, one-third of a grain 
 in the morning, and one-third of a grain more 
 in the evening. Then I followed this up with 
 daily two-third grain doses for six days, then 
 two doses of the same amount for the next three 
 
50 SCIATICA 
 
 days, then two doses in five days, and the last 
 one in six days afterward. After this I was free 
 from pain. My leg, which was three inches 
 smaller than the opposite one, is now about its 
 natural size. I am a thousand times your debtor 
 for the theine you sent me, for I have full confi- 
 dence that it gave me relief ; and, so far as my 
 sciatica is concerned, it made a cure without 
 any bad effects." 
 
 Dr. Washington H. Baker, of Philadelphia, 
 reports the following case : — 
 
 Case xi. — L. N. W. ; aged 36 ; consulted me, 
 Dec. 13th, 1885, on account of pain in his 
 left hip, from which he had been suffering for 
 eight months. Never had any disease of the 
 genitalia. Has not had chills and fever, nor 
 rheumatism. Had an attack of typhoid fever 
 thirteen years ago, and been well ever since 
 until the present trouble appeared. The greatest 
 pain complained of is in the left hip, a little 
 above the trochanter major; the pain also radi- 
 ates around in front and down back of thigh. 
 
SCIATICA 51 
 
 The pain does not extend below the knee at 
 present. Some time ago it extended to ankle 
 joint. Tongue clean ; bowels regular ; appe- 
 tite good. Is compelled to use a cane, and 
 limps when walking. 
 
 Dec. i6th. Gave a subcutaneous injection of 
 twenty minims of a two per cent, solution of 
 theine. He felt better at once and could stand 
 straighter. In a few minutes had a tingling 
 sensation. Can walk more erect and with less 
 pain. The thigh feels numb when touched, the 
 leg less so. Half an hour after the injection the 
 thigh still felt numb, but he could not walk 
 quite so well. Was given five grains of iodide 
 of potassium thrice daily. The injection was 
 given about three inches above the seat of 
 pain. 
 
 17th. Injected twenty minims of theine. 
 Helped him some, but not a great deal. Ap- 
 plied a thapsia plaster to thigh. 
 
 1 8th. Less pain since yesterday. Injected 
 twenty-five minims of same solution of theine. 
 
52 SCIATICA 
 
 19th. Walked down town to office this morn- 
 ing, a distance of twenty squares. Is feeling 
 much better. Injected thirty minims of same 
 solution. 
 
 2 1 St. Feels better than he has yet. Injected 
 twenty-five minims. 
 
 24th. Yesterday morning the pain returned 
 in the limb. Last night it was just as bad as 
 ever. Injected twenty minims, and after three 
 minutes the pain began to grow less. 
 
 25th. Still considerable pain. Injected twenty- 
 five minims. 
 
 26th. Had severe pain last night. Injected 
 twenty-five minims. 
 
 28th. Still considerable pain. I gave him a 
 pill of cinch, sulph., ext. nucis vomicae, ext. 
 belladonnae and pil. ferri carb. 
 
 Jan. 6th. Better. Injected twenty-five min- 
 ims of theine. 
 
 30th. Walked into office to-day, erect, very 
 little pain, and only a slight limp. Considers 
 himself cured. 
 
SCIATICA 
 
 The following case was reported by Dr. C. 
 H. Castle, of Cincinnati, Ohio : — 
 
 Case xii. — Neuralgia of the sciatic nerve . 
 chloroform, ether, etc., had failed as curative 
 remedies, or even to relieve pain. Temporary 
 relief was being sought in morphia. 
 
 4.05, Injected one-third grain of theine over 
 the course of the sciatic nerve near its emergence 
 from the pelvis. 
 
 4.10. Feels easier below seat of injection. Still 
 tenderness on pressure over the nerve. 
 
 4.20. Still somewhat better. 
 
 4.25. Jerking sensation when walking, no 
 pain when lying in bed. 
 
 4.35. Tingling sensation in heel ; walks much 
 better. 
 
 5.00. Numbness from knee down to foot ; 
 warm flashes. 
 
 5.30. Same feeling as at 5 p.m., with pain in 
 hip. 
 
 6.00. Pain not so severe in hip ; numbness 
 from knee down. 
 
54 SCIATICA 
 
 6.30. Complains of foot feeling very cold. It 
 communicates this sensation to the hand. 
 
 7.00. No pain, but still a sensation of cold. 
 Hot sand bags applied. Next morning pain 
 had returned. 
 
 The two following cases were reported to me 
 by Dr. George S. Gove, of Whitefield, N. H.:— 
 
 Case xiii. — Injury to hip joint, of one and 
 a half years' standing. The theine was used 
 at first in small and afterward in large doses 
 without any benefit, either alone or combined 
 with morphine and atropine. Nor had mor- 
 phine or atropine, combined or alone, any 
 influence on the pain. 
 
 Case xiv. — Patient aged forty-five ; em- 
 ployed in a creamery ; has had rheumatism ; 
 brought on a pain in his back by lifting a heavy 
 milk can ; worked all that day ; had a restless 
 night following ; next day was quite lame and 
 stiff; worked that day, but was used up by night 
 time. During the night of the third day he 
 had very little sleep on account of the severe 
 
SCIATICA 55 
 
 pain. Liniments and hot fomentations were 
 applied without effect. When I saw him next 
 niorning the pain was so great that in trying 
 to dress himself he fainted and fell to the floor. 
 I gave him one-half grain of theine hypoder- 
 matically, about ten inches above the hip joint, 
 and waited half an hour without affording much 
 relief. I then gave him another half-grain in- 
 jection, and the pain lessened. After a short 
 time the pain entirely disappeared and has not 
 returned since. 
 
 The following case was reported to me by Dr. 
 J. L. Seibert, of Bellefonte, Pa. : — 
 
 Case xv. — "On the 15th of September, 
 
 1886, I gave my patient, Mrs. L , who was 
 
 suffering intense sciatic pain, a superficial in- 
 jection of twenty drops of theine solution, a 
 little posterior to and above the trochanter 
 major. She complained of considerable burn- 
 ing, which, however, lasted only a few mo- 
 ments, and in twenty minutes all pain had left 
 her. At 12.30 a.m. (i6th) the pain had re- 
 
56 SCIATICA 
 
 turned ; I was called, and gave her -^^ gJ'^in of 
 morphine and jIq grain atropine hypodermati- 
 cally ; this gave her some ease, but she was not 
 free from pain, and spent the remainder of the 
 night without sleep. At 6 a.m. (same day, i6th) 
 I again injected twenty drops of theine solu- 
 tion, which in twenty-five minutes was followed 
 by complete relief from pain ; and again, at 
 9.30 A.M. (same day), when pain was returning, 
 though not severe, I gave her ten drops more 
 of theine solution, which relieved her entirely 
 of all pain for remainder of day. At 8.15 p.m. 
 I again visited her, and found her without pain, 
 resting very comfortably, when she said that 
 this was the first day she spent without pain for 
 a week ; but fearing a return of the pain during 
 the night, I gave her, at this visit, eight drops 
 m:ore of the theine solution. At my visit at 9 
 A.M., 17th inst., found her resting comfortably ; 
 no pain ; had slept well all night ; this morning 
 her nurse moved her to opposite side of bed 
 without hurting her or giving any pain. Ex- 
 
SCIATICA 57 
 
 amination of limb showed some little tenderness 
 on pressure over course of sciatic nerve — gave 
 her five drops of theine solution. Saw her 
 again at 7.15 p.m. (same day), when, for the first 
 time in two weeks, her limb had been laid out 
 straight alongside of its fellow — no pain now, 
 but complains of some loss of sensation in both 
 legs, though she can now move limbs herself. 
 This good condition lasted for three days and 
 nights, when the pain again set in, apparently 
 more severe than any time before, and then 
 theine in forty-drop doses subcutaneously gave 
 her no relief, and I was obliged to resort to mor- 
 phine, which quieted her again. This condi- 
 tion continued one week, when I stopped the 
 use of morphine, and since which time all pain 
 is again controlled by from ten to twenty drops 
 of theine solution, which she gets from one to 
 three times in two days. She is now conva- 
 lescing. 
 
 "All injections were made in region of left 
 hip (seat of trouble), and so thoroughly did 
 
58 INTERCOSTAL 
 
 theine deaden sensibility in this vicinity that the 
 hypodermatic needle was introduced without the 
 knowledge of the patient." 
 
 Case xvi. — January 7th, 1886; case of 
 double sciatica of fourteen years' duration in a 
 gentleman sixty-five years old. Theine injec- 
 tions relieve the pain, but are powerless to cure 
 the degeneration which had probably taken 
 place in the nerves. 
 
 INTERCOSTAL NEURALGIA. 
 
 Case xvii. — B. D. ; aged sixteen ; December 
 31st, 1885; complained of constant pain in right 
 chest, which began about three or four months 
 previously. She coughed and had a yellow 
 expectoration ; her appetite was variable, and 
 she had nausea, and a disgust for fatty food ; 
 felt chilly and hot occasionally, but her heart 
 and lungs were normal. It was found that she 
 had tender spots along the spine, and pressure 
 there increased the pain in the right side of the 
 chest. She was placed on tonic treatment, and 
 on the fifth of the following month she returned 
 
NEURALGIA 59 
 
 and reported herself no better. Theine injec- 
 tion in the back relieved the pain at once. At 
 this visit she also received the quinine and 
 ammonia mixture. She failed to present her- 
 self again. 
 
 Case xviii. — H. H. ; aged sixty-four; was 
 first seen March 25th, 1886, when he had pain 
 in chest ; cough and copious expectoration ; no 
 haemoptysis; malaria and rheumatism. Is 
 addicted to the use of alcohol, and gives evi- 
 dence of general bronchitis. Pressure along 
 left side of the spine in interscapular region 
 intensifies the pain in front of the chest. In- 
 jected half a grain of theine between shoulder 
 blades, left side. April ist: Better. Pain nearly 
 all gone. Gave him another theine injection 
 and prescribed a mixture for his cough. 
 
 Case XIX. — H. C. ; aged thirty ; on April 22d, 
 1886, applied for relief of a severe pain at base 
 of his right chest, which was aggravated by 
 a deep inspiration. Had some cough and 
 expectoration ; was losing flesh ; felt bad, but 
 
6o INTERCOSTAL NEURALGIA 
 
 never had malaria, rheumatism or syphihs. 
 Lungs and heart normal. Tender spots along 
 right side of spine. Injected one-half grain of 
 theine over latter area. April 24th : Pain 
 entirely gone. Also prescribed the quinine and 
 ammonia mixture. 
 
 Case xx. — May ist, 1886, L. M. ; aged fifty; 
 complained of constant pain in the cardiac 
 region, as well as of dyspnoea, and of some pal- 
 pitation of the heart. Coughed, and had a yel- 
 low expectoration. Heart and lungs normal. 
 Injected one-half grain of theine along left side 
 of spine at junction of fifth rib. May 4th : 
 Pain in region of heart much better. May nth : 
 Improved. Also gave him the quinine and 
 ammonia mixture. 
 
 Case xxi. — J. S.; aged twenty-four; was first 
 seen April 14th, 1887, when he had an ill- de- 
 fined pain in the left side of his chest — above 
 and in the cardiac area ; had some dyspnoea 
 and palpitation of the heart and also had 
 malaria and rheumatism. Heart and lungs 
 
DORSAL OR INTERSCAPULAR NEURALGIA 6l 
 
 normal. Injected one-half grain of theine in 
 left interscapular region. April 15th: Pain 
 was entirely relieved ; gave him another injec- 
 tion. April 20th : Still improving. Another 
 injection over anterior seat of pain. Also pre- 
 scribed quinine and ammonia, and with an occa- 
 sional injection afterward, he became well. 
 
 Case xxii. — Mr. B.; aged thirty; was entirely 
 relieved of intercostal neuralgia, accompanied 
 by a peculiar constant burning pain in the left 
 interscapular space, by one injection, which was 
 given over painful spot along left side of spine. 
 
 dorsal or interscapular neuralgia. 
 
 Case xxiii. — M. C. ; aged thirty. Pain only 
 between shoulder blades, at which point there 
 is a feeling as if she were in constant contact 
 with *' a lump of ice." Injected one-half grain 
 of theine over affected spot, and gave her the 
 quinine and ammonia mixture. She began to 
 improve at once, and the cold feeling did not 
 return as long as she was under observation. 
 
62 CERVICO-BRACHIAL 
 
 Case xxiv. — On the 27th day of April, 1886, 
 E. complained of interscapular pain, which was 
 relieved at once by the injection of one-half 
 grain of theine. 
 
 CERVICO-BRACHIAL NEURALGIA. 
 
 Case xxv. — H. K. ; aged nineteen ; was first 
 seen February 9th, 1886, when she suffered with 
 intermittent pain in right shoulder and in arm 
 along the ulnar nerve. Injected one-half grain 
 of theine at base of neck, and internally gave 
 her the quinine and ammonia mixture. April 8th: 
 No return of pain and feels good. 
 
 Case xxvi. — Dec. 17th, 1885, Mrs. M.; aged 
 fifty ; suffering from cervico-brachial neuralgia 
 on right side since the previous August. Two 
 injections of half a grain each, a week apart, 
 were sufficient to relieve the pain. 
 
 The following cases were reported by Dr. 
 William Hall, of Conshohocken, Pa.: — 
 
 Case xxvii. — I have used theine in three 
 cases; two of cervico-brachial and one of in- 
 
NEURALGIA 63 
 
 tercostal neuralgia. The case of intercostal 
 and one of cervico-brachial neuralgia were en- 
 tirely relieved. In the other case theine failed, 
 as did all other remedies. This last case is a 
 woman, whose father died of, and whose sister is 
 suffering from, a similar form of pain. I am 
 well pleased with the remedy in a fair case. 
 
 Dr. G. D. Bennett, of Newton, Kansas, re- 
 ports the following case : — 
 
 Case xxviii. — In regard to my patient treated 
 with theine, I would say that Mr. G. fell from 
 his wagon in the early part of November, 1885, 
 and dislocated his shoulder downward into the 
 axilla, and also injured the brachial plexus of 
 nerves, in the fall. The injury was followed by 
 some pain, which grew to such severity that 
 one-half grain doses of morphine gave him but 
 partial relief. Some six weeks after receiving 
 the injury, and when the pain in the shoulder 
 was steadily growing worse, I commenced 
 using theine hypodermatically, by injecting one- 
 third of a grain in the morning. The result of 
 
64 OCCIPITAL NEURALGIA 
 
 the first injection was some redness and pain at 
 seat of injection, and in fifteen minutes numb- 
 ness of finger ends appeared, which gave way, 
 in half an hour, to a condition explained by 
 patient as "arm being asleep." In a short 
 time, probably forty minutes, pain in shoulder 
 all gone. Next day visited patient, and found 
 return of pain, but not so severe as before, and 
 again injected one-third of a grain, which re- 
 lieved him to such an extent that he had a 
 comfortable day and an easy night. This treat- 
 ment, for the next twenty days, was combined 
 with tonics, at the end of which time my patient 
 had complete use of his arm and no pain. I 
 feel that we now have a remedy which is cer- 
 tainly far superior, at least was in this case, to 
 morphine and cocaine, for they both had been 
 tried thoroughly here. 
 
 OCCIPITAL NEURALGIA. 
 
 Case xxix. — O. C; aged forty-five; com- 
 plained of severe pain in the region of the oc- 
 
RHEUMATIC NEURALGIA 65 
 
 ciput, on April 29th, 1886. The pain was par- 
 oxysmal, and appeared about every three weeks. 
 Injected half a grain of theine on each side of 
 head, which relieved her. May 8th. No return 
 of pain. 
 
 RHEUMATIC NEURALGIA. 
 
 Case xxx. — Mrs. J. E.; aged fifty; consulted 
 me, June loth, 1886, concerning a pain and 
 swelling in right knee. She had been subject 
 to rheumatism, off and on, for the last twenty 
 years, but eleven months ago she fell and hurt 
 her knee, since which time she limps when she 
 walks. Examination shows a tender spot in 
 right hip joint. Injected half a grain of theine 
 there, and, internally, gave her the soda sali- 
 cylic mixture. Returned on the 12th, and stated 
 that the pain in the hip had disappeared, but 
 the knee still pained as before. Injected half 
 a grain of theine above and below the knee, 
 which relieved the pain in the latter place so 
 much that she could walk without limping. 
 
66 RHEUMATIC NEURALGIA 
 
 June 17th. Says she has less pain than she 
 had for eleven months. Gave her two more 
 injections, above and below knee, and same 
 internal treatment. 
 
 August 30th. Feels good. There can be no 
 doubt that, considering the age of this patient, 
 as well as her predisposition to rheumatism, that 
 the pain will return some time. 
 
 Case XXXI. — April 22d, 1886, S. E.; aged fifty; 
 an old rheumatic; complains of pain in left 
 wrist, arm and ankle joint. Injected half a 
 grain in arm and above ankle. Gave her, in- 
 ternally, the sodium salicylate mixture. 
 
 27th. Feels good. Pain in arm and joints 
 gone. Continued same internal treatment. 
 
 Case xxxii. — (Reported by Dr. Washington 
 H. Baker.) March 8th, 1886, a gentleman, fifty- 
 eight years old, told me that he had been suffer- 
 ing for several weeks with a pain in the left 
 shoulder. He supposed it was rheumatism. 
 He had been kept awake the greater part of 
 the last three nights, on account of the pain. 
 
SPINAL IRRITATION 67 
 
 The pain was getting worse from day to day. 
 I injected twenty-five minims of a two per cent, 
 solution into the shoulder, with immediate relief. 
 That night he slept comfortably, and has not 
 had any pain in shoulder up to date (March 
 20th, 1886). After the injection, a burning, 
 tingling sensation was complained of at site of 
 injection. The theine had no appreciable effect 
 on the mental faculties. 
 
 Case xxxiii. — Dec. 5th, 1885, V.; chronic 
 rheumatic pain of left shoulder joint and whole 
 arm. Pain very severe. No relief rendered 
 previously by salicylates, ammonium chloride, 
 iron, quinine, or potassium iodide. Half a 
 grain of theine above shoulder joint made him 
 comfortable at once. 
 
 spinal irritation. 
 
 Case xxxiii. — February 3d, 1886, W.; aged 
 thirty. This was a most aggravated case of 
 neuralgia of both lumbo-sacral and left cervico- 
 brachial plexuses, associated with irritability of 
 the spine along its whole course. The pain had 
 
68 SPINAL IRRITATION 
 
 been coming on for two months or more. It 
 was intermittent, very intense, and accompanied 
 by muscular contractions of both legs below 
 the knee, and left forearm. It was impossible 
 for the patient to stand erect when he suffered 
 from the pain — in fact, he was confined to his 
 bed most of the time. Four injections, of one- 
 sixth grain each, in the evening, made him 
 comfortable during the night and next day 
 until evening, while with other remedies, like 
 potassium iodide, iron, ammonium chloride, 
 quinine, phosphoric acid, strychnine and cod- 
 liver oil, have been kept up for nearly three 
 weeks, and now (March ist) the patient is in a 
 good condition, able to walk twenty-five squares 
 in one stretch, and only requires an occasional 
 injection. The injections were all made on 
 each side of the spine, in the interscapular and 
 lumbo-sacral region, and never failed to give 
 him instantaneous relief, no matter how severe 
 the pain was at the time. 
 
NEURASTHENIA 69 
 
 NEURASTHENIA. 
 
 Case xxxiv.— (Reported by Dr. H. Wod- 
 drop, Loag, Pennsylvania.) M. ; married ; aged 
 forty ; was found, last December 4th, with con- 
 siderable pain, of intermittent character, in left 
 leg. For a month previous he had been suffer- 
 ing with occasional twitches of pain, and was 
 now confined to his couch. He also had stiff- 
 ness as well as oedema in his other limb. He 
 was treated with morphine (by the mouth and 
 subcutaneously), ammonium chloride, quinine, 
 iron, strychnine, and arsenic, until the last of 
 December, when the swelling had entirely dis- 
 appeared, but there were considerable pain and 
 stiffness left in the limbs. About this time I 
 saw your article on theine, procured some, and 
 injected one- fifth of a grain deep into the calf 
 of the left leg. This caused some pain, and 
 succeeding symptoms were very near your de- 
 scription. Continued internal treatment and 
 subcutaneous injection of theine occasionally. 
 On January 19th changed internal treatment 
 
70 OTHER PAINFUL DISEASES 
 
 to small doses of phosphorus, beef peptonoids 
 and milk. On January 23d could move his 
 limbs freely, had no pain, and appeared, ex- 
 cepting debility, a well man. He received, in 
 all, twenty-four injections, sometimes twice a 
 day. I attribute his recovery, in great part, to 
 theine, but the constitutional treatment was 
 also very important. I have no doubt that, by 
 the use of theine, I shortened the case materi- 
 ally. The burning which was occasioned by 
 the injections lasted about fifteen minutes, after 
 which the pain in the limbs ceased. The pain 
 returned at varying periods, not as severe after 
 the injections as before, and it always subsided 
 directly after the use of theine. I believe theine 
 to be a perfect analgesic, and have noticed no 
 narcotic effects from its employment. 
 
 THEINE IN THE TREATMENT OF OTHER PAIN- 
 FUL DISEASES. 
 
 I think sufficient evidence has now been ad- 
 duced to show the usefulness of theine in pure 
 and uncomplicated nerve pain, or in diseases in 
 
OTHER PAINFUL DISEASES 7 1 
 
 which the pain is strictly hmited to the sensory 
 nerves. In the succeeding pages, proof will be 
 offered to show that it is also a true analgesic in 
 those kinds of pain which are not supposed to 
 be absolutely confined to nerve tissue, viz. : 
 muscle pain. On the whole, it may be said, how- 
 ever, that the distinction between nerve and 
 muscle pain is more artificial than genuine. 
 Although the organs of sensation and of motion 
 are intimately associated, and are both evolved 
 out of the same fundamental tissue, practically, 
 there can be no sensation or pain independent 
 of nerve tissue. Hence, while it is true that in 
 myalgia there is a diffusion of pain rather than 
 localized spots of pain along the trunk of a 
 nerve, as in neuralgia ; that the pain of myalgia 
 is more aggravated by movement than that of 
 neuralgia ; and while it is true that there are 
 other clinical differences between the two affec- 
 tions, there is reason for believing that the pain 
 of myalgia is as truly nervous as that of 
 neuralgia. 
 
72 MYALGIA 
 
 Below will be presented the histories of some 
 cases of myalgia and of lumbago, as well as of 
 other non-neuralgic diseases, in which theine 
 yielded as good service as it did in those of 
 neuralgia. 
 
 MYALGIA. 
 
 Case xxxv.— (Reported by Dr. Castle, of 
 Cincinnati, Ohio) Myalgia of the deltoid 
 muscle. Pain severe. Had had one-quarter 
 grain of morphine every two hours the night 
 before, without bringing sleep. Could not raise 
 arm. 
 
 9 p. M. One-sixth grain of theine subcu- 
 taneously about the anterior margin of the 
 trapezius, just above the shoulder ; pulse, 102. 
 
 9.04. Very little pain, unless she moved her 
 arm. Still marked tenderness on pressure. 
 
 9.05. Pulse 96. Diminished sensibility about 
 seat of injection. 
 
 9.10. Seat of pain seemed to be only in lower 
 half of its former area. 
 
MYALGIA 73 
 
 9.13. Numb feeling in arm as far down as 
 elbow. Very little pain on moving arm. 
 
 9.15. Can now bear pressure over former 
 exquisitely tender spot. 
 
 9.20. Pulse 96. Only tenderness is now over 
 acromion. No pain at all on pressure over 
 anterior part of arm. 
 
 9.30. Numbness not so marked. Says, if only 
 had as much pain as she now has, she could 
 easily bear it. 
 
 9.37. Pain now only about insertion. 
 
 9.40. Numbness in arm diminishing, but pain 
 not increasing. Says she could go to sleep. 
 
 11.00. Pain, has returned, but in a much less 
 degree. Needs no morphine. 
 
 Since then has not complained. 
 
 Case xxxvi. — April 7th, 1886. M. G., aged 
 32, suffered from severe pain in and below left 
 shoulder joint. Injected half a grain of theine, 
 which relieved him before he left the office. 
 Never saw him again. 
 
74 LUMBA.GO 
 
 LUMBAGO. 
 
 Case xxxvit. — March 25th, 1886. D. O.; 
 aged 44 ; laborer ; complained of severe pain in 
 back, which was almost exclusively confined to 
 the lumbar region. Cannot bend body, or sit 
 down without a great deal of pain. Walks 
 very stiffly. These attacks occur periodically. 
 Injected one-third of a grain of theine on each 
 side of the sacrum, and in a few minutes he 
 was able to stoop, and sit down without any 
 inconvenience. He expressed himself as being 
 well pleased. 
 
 Case xxxviii. — April 29th, 1886. G. T.; aged 
 33 ; laborer ; suffers from pain and weakness in 
 the lumbar muscles. Injected half a grain of 
 theine on each side of painful region. 
 
 May 8th. Less pain since injection. Injected 
 another half- grain. 
 
 Oct. 9th. No pain in back since last injec- 
 tion. 
 
 Case xxxix. — March 30th, 1886. S. M.; aged 
 45. Has had fever and ague and complains of 
 
LUMBAGO 7 5 
 
 pain in the lumbar region. She says, " The 
 pain catches me in the back when I rise." 
 Gave her quinine and iron. 
 
 April 1st. Pain in back very severe. She now 
 received half a grain of theine over painful 
 spot, and she felt better at once. Same internal 
 treatment. 
 
 April 17th. No return of pain. 
 
 Case xl. — (The two following cases were 
 reported to me by Dr. Baker.) J. B. came to 
 me in December, 1885, complaining of a severe 
 pain in the lumbar region, which almost inca- 
 pacitated him for work. Injected twenty-five 
 minims of a two per cent, solution of theine in 
 lumbar region above painful part. He was 
 relieved at once, and has not been troubled 
 with it since. 
 
 Case xli. — J. R. W.; aged thirty years ; brake- 
 man ; suffered from pain in the lumbar region, 
 which troubled him, particularly when he bent 
 over to wash his hands. I injected twelve 
 minims of a two per cent, solution of theine 
 
^6 MUSCULO-RHEUMATIC PAIN 
 
 under the skin above the painful spot, with 
 immediate and entire rehef of pain. It was 
 really ludicrous to see the astonished expres- 
 sion on his countenance, and the contortions 
 he went through to assure himself that he was, 
 in truth, relieved. I also gave him two and a 
 half grains of potassium iodide thrice daily. 
 
 Dec. 22d. Injected twenty-five minims of 
 theine, as there was a suspicion of pain in the 
 back. This visit was one week after the first. 
 
 Jan. 1 2th, 1886. Reports no trouble with his 
 back. 
 
 MUSCULO-RHEUMATIC PAIN. 
 
 Case xlii. — (Reported by Dr. Castle.) The 
 patient was the subject of those ill defined' 
 dragging, musculo-rheumatic pains of the 
 extremities, found not infrequently in such a 
 damp climate as is ours. About one year ago 
 he had obtained marked relief from an electric 
 bath, taken in Chicago, and at the time I 
 encountered him he was on a search for a 
 similar electropathic institution in Cincinnati. 
 
PAIN OF LOCOMOTOR ATAXIA "J^ 
 
 I persuaded him to allow me to use one-sixth of 
 a grain of theine upon him hypodermically. The 
 pain was severe in the anterior muscular masses 
 of both thighs and in the calves of both legs. 
 I made my injection slightly below the popliteal 
 space, and toward the inner side of the leg. 
 The effect was striking and almost instanta- 
 neous. The point of injection, though angry- 
 looking, was quite ansesthetic, and as little 
 tinghngs shot down the leg toward the foot, the 
 pain vanished and the analgesia of the in- 
 jected leg was in marked contrast to the pain 
 in the thigh of the same extremity and the 
 thigh and leg of the opposite extremity. This 
 beneficial effect was maintained for a few days, 
 at which time I last saw the patient, and I 
 exceedingly regret that we have neither of us 
 had the time or opportunity to relieve the still 
 suffering fragments of his body of their aches. 
 
 PAIN OF LOCOMOTOR ATAXIA. 
 
 Case xliii.— April 4th, 1886. J. P.; aged 50. 
 Suffering for three years from locomotor ataxia. 
 
y2> PAIN OF 
 
 Has been unable to walk or move his arms for 
 three months, and on account of the pain in 
 the back, arms and legs he is compelled to pass 
 days and nights without sleep. Has well- 
 marked constriction around the base of his 
 chest and suffers from oedema and spasmodic 
 contractions of both extremities. This patient 
 received two and a half grains of theine every 
 other day, in different spots along the spine, with 
 the effect of giving him relief to his pain. This 
 course was pursued for about four months, and 
 while it did not ameliorate his general condi- 
 tion, it gave him sleep, relieved the pain and 
 contractions in the back and extremities, 
 removed the thoracic constriction, and, on the 
 whole, it made the patient feel more comfort- 
 able than he was before. 
 
 It is but fair to state here that, in another case 
 of locomotor ataxia, the theine injections sig- 
 nally failed to relieve the pain. This patient 
 was, however, addicted to the protracted use of 
 large doses of morphine, and the pain of which 
 
LOCOMOTOR ATAXIA 79 
 
 he complained was chiefly referred to the 
 stomach, and, no doubt, partook of the nature 
 of opium pain. This was promptly relieved by 
 the subcutaneous administration of morphine. 
 
APPENDIX. 
 
 Dr. Charles K. Mills, President of the Phila- 
 delphia Neurological Society, made the following 
 remarks on a paper entitled " Theine in Pain," which 
 I had the pleasure of reading before that Society, De- 
 cember 19th, 1887 [copied irova Jozirnal of Nervous 
 Diseases^ January, 1888] : — 
 
 "A few months ago I began the use of theine, or- 
 dering it in nearly every case of neuralgia, superficial 
 neuritis or lumbago that came to the Polyclinic service, 
 and also using it at the Philadelphia Hospital. I 
 have used the drug probably in about fifteen cases, 
 but I have not had time to prepare notes of them for 
 this meeting. I recall three cases of sciatica, two of 
 which were of long standing. These cases were all 
 m proved, but none of them were cured, by the use 
 of theine alone. The pain was usually much relieved 
 by the hypodermatic use of theine, but it would re- 
 turn after a shorter or a longer time. In connection 
 with the theine, I used galvanism to the nerve and 
 muscles, and internally Donovan's solution, or iodide 
 of potassium. Two of the cases of sciatica were 
 cured under this conjoint treatment. 
 81 
 
82 APPENDIX 
 
 *' In a case of facial neuralgia, or neuritis, I used a 
 hypodermic of theine in the face ; following this, the 
 patient became pale, sick at the stomach, and seemed 
 to be in a slightly dazed condition for a time. Whether 
 this was due to the drug or simply to the slight oper- 
 ation, I cannot say. The injection entirely relieved 
 the pain for three days. The patient then returned, 
 and another injection was given, without bad effect. 
 In another facial case the patient was certainly re- 
 lieved by theine, and, so far as I know, remained 
 well. 
 
 " I have used it in the back with great benefit in 
 so-called myalgia, including under that term muscular 
 rheumatism, and possibly true lumbar neuralgia. 
 
 " I believe that theine is an analgesic ; that it re- 
 lieves pain in cases of recent and superficial neuritis, 
 or neuralgia. In chronic, painful nerve troubles, par- 
 ticularly where the nerves are deeply situated, it seems 
 to be simply a helping remedy, and sometimes fails."
