Felter's Materia Medica on Rheum

ÆSCULUS GLABRA
   The bark and fruit of Aesculus glabra, Willdenow (Nat. Ord. Sapindaceae). A small fetid tree common to the central portion of the United States. Common Names: Ohio Buckeye, Smooth Buckeye, Fetid Buc eye. Principal Constituents.—The glucoside aesculin (C15 H16 O9) (displays a blue fluorescence in water and more strongly in the presence of alkalies); aesculetin (C9H6O4); a peculiar tannin and saponin. Starch is abundant and a rich yellow oil is present. Preparation.—Specific Medicine Aesculus. (Made from the ripe fruit.) Dose, 1 to 15 minims. The smaller doses are to be preferred. Specific Indications.—Sense of constriction, tightness, or uneasiness in the rectum, with or without hemorrhoids; intestinal irritation with constriction and colicky pain near the umbilicus; dyspnea and constriction of the respiratory tract with spasmodic cough. Action.—The dried, powdered fruit of the buckeye causes violent sneezing. Buckeye acts powerfully upon the nervous and circulatory systems. Its action is probably strongest on the spinal nerves, and in some respects resembles that of strychnine. The cerebrum is also impressed by it. Toxic symptoms include dizziness, fixation of the eye, impaired vision, vomiting, wry-neck, opisthotonos, stupor, and tympanites. In lethal doses these symptoms are increased, coma comes on, and the victim dies. Cattle are often killed by eating buckeyes; if not fatal, a condition known as "blind staggers" is produced. Therapy.—Aesculus is sedative, somewhat narcotic, and has a special control over the portal circulation, relieving venous congestion. When the circulation is rapid and the constrictive sensation prominent and dyspnea prolonged, it relieves such conditions as continuous asthmatic breathing. There is a sense of constriction back of the upper portion of the sternum, with or without irritative cough, that is relieved by it. It is useful in intestinal irritability with the contractive colic-like pain centering in the umbilical region, probably dependent most largely upon hepatic or portal congestion and associated with chronic constipation. Its chief value, however, lies in its power to relieve hemorrhoids due to faulty hemorrhoidal circulation. The sense of fullness and tightness rather than marked pain is the indication for it. It often succeeds admirably, and as often completely fails to relieve. Its action upon visceral disorders is practically the same as that mentioned under Hippocastanum (which see). Aesculus sometimes relieves uterine congestion with full tumid and enlarged cervix and too frequent and profuse menstruation. This would suggest its possible value in uterine subinvolution. It has a domestic reputation for the cure of rheumatism, but this has not been verified to any great degree in professional practice. It has been suggested as a spinal stimulant in paralysis. If so used it should be used like strychnine after active symptoms have ceased, and to stimulate the unimpaired nervous tissue. Aesculus deserves further study to determine its status as a remedy for nervous disorders, and especially its control over visceral neuralgias. 1

ARNICA MONTANA
   The dried flower-heads of Arnica montana, Linné (Nat. Ord. Compositae). A perennial of Siberia and the cooler parts of Europe; also found in Northwestern United States (? —MM). Dose, 1 to 10 grains. Common Names: Arnica, Leopard's Bane. Principal Constituents.—Arnicine (C12 H22 02), a golden-yellow body, a volatile oil, and angelic and formic acids. Preparations.—1. Specific Medicine Arnica. Dose, 1/4 to 10 drops. 2. Tinctura Arnicæ, Tincture of Arnica. Locally. Specific Indications.—“Muscular soreness and pain from strain or overexertion; advanced stage of disease, with marked enfeeblement, weak circulation, and impaired spinal innervation; embarrassed respiration; lack of control over urine and feces; sleeplessness from impeded respiration; and dull praecordial pain from ‘heart strain’; muscular pain and soreness when the limbs are moved; tensive backache, as if bruised or strained; cystitis, with bruised feeling in bladder, as from a fall or blow; headache, with tensive, bruised feeling and pain on movement; hematuria, with dull, aching, lumbar pain; or from overexertion. Debility with enfeebled circulation." (American Dispensatory.) Action.—Arnica is a decided irritant to the skin, under some circumstances producing marked dermal irritation, deepening into an erysipelatous or acute eczematous inflammation, with pustules and blisters, and often grave constitutional symptoms. In this respect the alcoholic preparations of the flowers are most active, and for this reason full strength preparations should not be used upon the skin, nor as a rule should any preparation of arnica be used upon cuts or injuries causing a breaking of the skin. Under the latter conditions dangerous inflammation, with vesication, has occurred. Persons of sensitive skin, and it is said gouty subjects, are most susceptible to this untoward action of the drug. Medicinal doses of arnica slow the heart, slightly raise arterial pressure, and stimulate the vagi. Poisonous doses operate reversely and paralyze the vagal centers. Intermediate but large doses produce heat in the throat, nausea and vomiting, dyspnea, headache, lowering of temperature, and sometimes convulsive movements. With toxic doses these effects deepen into unconsciousness, motor, sensory and vagal paralysis, coma, and death. Death is said to have been caused by two ounces of tincture of arnica. Therapy.—External. Arnica, in tincture or fomentation, has long been a popular but by no means safe discutient to prevent and discuss inflammatory swellings, and to relieve the soreness of myalgia and the effects of sprains, bruises, and contusions. It is often serviceable to remove ecchymoses, and it gives grateful relief to sore muscles that have undergone much strain and exertion. A glycerite has been effectually used upon bites of mosquitoes and other insects. Preparations of the root are less liable to excite dermatitis, and the infusion of the flowers is less irritant than the tincture. After applying the latter, which should always be well diluted, the surface should not be covered or bandaged, so that evaporation may take place freely. Internal. Arnica is a greatly unappreciated medicine. It has a pronounced action upon the medulla and spinal cord which can be invoked to good advantage in states of depression. The keynote for arnica is spinal and vagal enervation. It should be brought into service when there is deficient nervous response, sluggish vascular power, and in almost all conditions in which prevails the triad-torpor, debility, and depressed function. In the advanced stages of exhausting diseases, where spinal innervation is poor, control over the sphincters lost, and there is feeble respiration due to central vagal impairment, it is a most important stimulant. It should be used when breathing can be carried on chiefly only by force of the will, and becomes weak and shallow when the patient drops into sleep; or when the sleeper awakens with a start on account of dyspnoea when automatic respiratory action alone is depended upon. Such a state occurs in the low stage of typhoid and other fevers, and in lobar pneumonia. In such conditions arnica is most useful and compares well with strychnine or atropine, or phosphorus, none of which are so safe as arnica. Arnica will prove useful in the depression occasioned by extreme forms of diarrhoea and dysentery when the discharges escape control. In so-called typhoid pneumonia—which is but pneumonia with typhoid conditions— marked asthenia, feeble circulation, great depression, low muttering delirium, picking at the bed clothes, and dry tongue loaded with foul mucus and sordes, it is a most valuable auxiliary to other treatment. In the hectic fever of phthisis, with exhausting diarrhoea and excessive sweating, it often proves the needed stimulant and antihydrotic. Arnica is a stimulant of great power in anemia, with weak heart and capillary feebleness, and marked depression, diarrhoea and dropsy, but no inflammation. During mild forms of so-called chronic rheumatism, with cold skin and general debility it will stimulate the nervous system, restore normal warmth, re-establish restrained secretion, and thus relieve pain. In painful, bruised or subacute inflammatory disorders arising from injury, with marked lowering of nerve tone, muscular aching and chilly sensations, arnica is a remedy of power to give comfort and hasten resolution. When myalgia is caused by exposure, or when muscular soreness and pain are due to strain, overexertion, or sudden jars or blows, the administration of arnica internally, in small doses of the specific medicine preferably, and the diluted tincture applied locally are among the most serviceable of measures. Arnica frequently relieves “heart-strain” due to exertion, overwork, or from long marching. It also benefits in the heart debility that follows severe strain, worry, or excitement. Dull aching pain in the praecordia, due to lifting or when working against vibrating machinery, 1

ASCLEPIAS SYRIACA
   The root of Asclepias syriaca (Asclepias Cornuti, in the original), Decaisne (Nat. Ord. Asclepiadaceae). Common in rich soils throughout the United States. Dose, 1 to 60 grains. Common Names: Milkweed, Common Milkweed, Silkweed, Wild Cotton. Principal Constituents.—The milky juice contains a caoutchouc-like body. The root contains a glucoside, not yet fully determined and a volatile oil and a bitter principle. Preparation.—Tinctura Asclepiadis Cornuti, Tincture of Asclepias Cornuti (8 ounces; Alcohol, 16 ounces). Dose, 5 to 60 drops. Action and Therapy.—External. It is a common practice among the laity to remove warts by the application of the fresh, milky juice of the plant. Krausi believed it effective in removing small epitheliomata. Internal. As the root possesses tonic, diuretic, and anthelmintic properties it may be used occasionally for the functions indicated. The heart-action is stimulated by it, and it has been suggested as a useful remedy in muscular rheumatoid affections, acting much like macrotys. Constipation is said to be favorably influenced by it, and in full doses it is recommended to expel intestinal worms. The drug deserves study. The young “shoots” or turiones are a favorite pot-herb or “greens” in some sections of our country. 1

AVENA SATIVA
   The unripe seed of the Avena sativa, Linné, and the farina derived from the ripened seed (Nat. Ord. Graminaceae). Probably indigenous to Sicily and to an island off the coast of Chili. Cultivated everywhere. Common Names: Oat, Common Oat. Principal Constituents.—Starch, oil, albumen, potassium and magnesium salts, silica, and a nitrogenous body, avenine. Preparations.—1. Avenae Farina, Oatmeal. Chiefly a food and to prepare oatmeal water. 2. Tinctura Avenae, Tincture of Avena. (Cover best unripe oats [in “milk”] with strong alcohol.) Dose, 1/2 to 2 fluidrachms. 3. Specific Medicine Avena. Dose, 1/2 to 2 fluidrachms. Specific Indications.—Nervous exhaustion; nervous debility of convalescence; cardiac weakness of nervous depression; nocturnal losses following fevers and from the nervous erethism of debility; nervous headache from overwork or depression. Action and Therapy.—Oatmeal water is sometimes useful to dilute “baby foods” and milk when children are not well nourished and suffering from summer diarrhoeal disorders. It is also used as a demulcent drink in diarrhea and dysentery of adults. When so used, it should be about the consistence of milk. Oatmeal gruel, when not otherwise contraindicated, as in diabetes mellitus or amylaceous indigestion, is an excellent and easily digested food in convalescence from exhaustive illness. It may be sweetened if desired. A paste, made by moistening a small quantity of oatmeal, held in the hands, with water, will soften roughened skin of the palms and fingers; and also remove the odor of some substances, as iodoform. Tincture of Avena is a mild stimulant and nerve tonic. It is regarded by many as a remedy of some importance for nervous debility, and for affections bordering closely upon nervous prostration. It seemingly acts well in the exhaustion following typhoid and other low fevers and is thought to hasten convalescence, particularly where there is much nervous involvement and enfeebled action of the heart. In the nervous erethism or the enervated conditions following fevers and giving rise to spermatic losses it is sometimes effectual, but it seldom benefits such a state when due to prostatic irritation, masturbation, or sexual excesses. It may be given to relieve spasms of the neck of the bladder; and in some cases of relapsing rheumatism. Webster asserts it is useful, not as an antirheumatic, but for the debility underlying the rheumatic diathesis, so that the patient is less affected by meteorologic influences. Probably its chief value as a medicine is to energize in nervous exhaustion with or without spasms. It is useful in headache from exhaustion or overwork, or the nervous headache of menstruation. It is not a remedy of great power and will be found effective, probably, in but few of the conditions mentioned. However, many agents of this type sometimes, in exceptional cases, accomplish that which no other remedy seems to do. To fortify some of the claims made for this remedy is to unwisely challenge the credulity of physicians of bedside experience. The much-heralded reputation of this drug to enable the morphine habitué to throw off the habit has not been sustained. In our own experience we have utterly failed to accomplish any good with it in any form of drug habit. 1

BELLADONNA (Atropa belladonna)ATROP
   The (1) dried root and the (2) dried leaves and tops of Atropa Belladonna, Linné (Nat. Ord. Solanaceae). Europe and Central Asia; also cultivated. Dose, (1) 1/4 to 1 grain; (2) 1/4 to 2 grains. Common Names: Deadly Nightshade, Dwale. (1) Belladonna Root (Belladonnae Radix); (2) Belladonna Leaves (Belladonnae Folia). Principal Constituents.—The poisonous alkaloids atropine, hyoscyamine, belladonnine, and hyoscine. There is much confusion concerning the constituents of belladonna, hyoscyamine, with conversion products, probably being the chief alkaloid. This is readily convertible in atropine. The alkaloids probably exist as malates. Preparations.—1. Specific Medicine Belladonna (prepared from the root). Dose, 1/20 to 1 drop. Usual method of administration: Rx Specific Medicine Belladonna, 5- 10 drops; Water, 4 fluidounces. Mix. Sig.: One teaspoonful every 1 to 3 hours. 2. Unguentum Belladonnae. Ointment of Belladonna. (This is prepared from the Extract of Belladonna, which in turn is prepared from Belladonna leaves. Tincture of Belladonna is also prepared from the leaves, while the fluidextract is prepared from the root.) Specific Indications.—Dull expressionless face, with dilated or immobile pupils, dullness of intellect, drowsiness with inability to sleep well whether there is pain or not; impaired capillary circulation either in skin or mucous membranes; dusky, deep-red or bluish face and extremities, the color being effaced by drawing the finger over the parts, the blood slowly returning in the whitish streak so produced; circulation sluggish, with soft, oppressed, and compressible pulse; cold extremities; breathing slow, labored, and imperfect; hebetude; the patient sleeps with eyes partially open; coma; urinal incontinence; free and large passages of limpid urine; fullness and deep aching in loins or back; spasm of the involuntary muscles. In 3x dilution the indications are: Pallid countenance, with frequent urination; nervous excitation, with wild and furious delirium. Large doses: mydriatic. Action.—The action of Belladonna depends largely upon its chief alkaloid Atropine. Therapy.—External. Belladonna, and more rarely atropine, may be applied for the relief of pain and spasm, and especially for spasmodic pain. A lotion of belladonna (5 to 10 per cent) may be used to allay itching in general pruritus, eczema, and urticaria. The tincture, painted upon the feet, controls local bromidrosis. A weak lotion is effectual in general hyperhydrosis and in the colliquative sweating of phthisis and other debilitating diseases. The ointment and liniment may serve a similar purpose. This use of belladonna is less desirable, however, than other medication on account of the dryness of the throat and mouth, and the ocular disturbance it is likely to occasion. Ointment of belladonna and the liniment are extremely useful in local inflammations and swellings, having a wide range of efficiency. Thus they may be applied to painful and swollen joints, forming abscesses, incipient and recurrent boils, buboes, hemorrhoids and fissures, inflamed glands, and in neuralgia, chronic rheumatism, lumbago, myalgia, pleurodynia, the chest pains of pulmonary tuberculosis, and in acute mastitis. In many of the surface conditions mentioned the plaster may prove most effectual. The liniment is especially useful to alleviate cramps in the calf of the leg. The ointment is effectual in relaxing rigid os during labor, and carried into the urethral canal of male or female it relaxes spasmodic constriction of that canal and cystic spasm and relieves pain. Rubbed on the under surface of the penis it has given marked relief in chordee. A suppository of belladonna relieves spasmodic dysmenorrhea and may be applied either in the vagina or the rectum. A similar application, with or without tannin or geranium, may be inserted into the vagina for painful menstruation, with leucorrhoea. The liniment and the ointment may be used as antigalactagogues and are especially serviceable after weaning the child or when mastitis threatens. All local applications of belladonna should be made with judgment and carefully watched lest poisonous absorption take place. In many of the conditions mentioned the conjoint internal use is advisable—provided the specific indications for the drug are present. Therapy.—Internal. Belladonna is employed in Eclectic Therapeutics in doses which produce exactly the opposite effects from the gross or physiologic and toxic action. Large doses paralyze; small doses stimulate. While employed for its physiological effects in some instances, the chief use of the drug with us is in conditions showing impairment of the capillary circulation in any part of the body with congestion or tendency to blood stasis. The size of the dose is of great importance in administering belladonna. Ordinary drachm doses of a dilution of 5 to 10 drops of the specific medicine in four ounces of water meet conditions of dullness, hebetude, and congestion, as first pointed out by Scudder. Others claim that the use of infinitesimal doses, of the 3x dilution, acts promptly in conditions of nervous exaltation, with great irritability and impressionability of all the senses; in some cases the hyperaesthesia amounts to delirium and it is then claimed to be most efficient to control both mild and furious outbreaks of delirium. Others again (and this agrees with our personal experience) find marked pallor of the surface, with contracted pupils, the indication, for minute doses of the drug. Following a law which appears to be commonly borne out in therapeutics, that opposite effects are produced by large or by minute doses respectively, belladonna seems a possible therapeutic agent in many varied conditions. The cases, however, in which belladonna appears to have rendered the best service are in those in what might be called medium doses, as advised by Scudder, in which the drug is employed to overcome dullness, hebetude, expressionless countenance1

CAMPHORA
   A stearopten (having the nature of a ketone) derived from Cinnamomum Camphora. (Linné), Nees et Ebermeier (Nat. Ord. Lauraceae). China and Japan. Common Names: Camphor, Laurel Camphor, Gum Camphor (it is not a gum). Description.—Tough, translucent white lumps or granules, having the pungent taste known as camphoraceous, and an aromatic penetrating odor. It dissolves freely in alcohol, chloroform, ether, and fixed and volatile oils; very slightly in water. Camphor is readily pulverized by triturating it with a few drops of alcohol, chloroform, or ether. Dose (by mouth), 1 to 5 grains; (hypodermatically) 1 to 3 grains. Preparations.—1. Spiritus Camphorae (10 per cent), Spirit of Camphor. Dose, 1 to 30 drops. 2. Aqua Camphorae. Camphor Water. Dose, 1 to 4 fluidrachms. 3. Linimentum Camphorae. Camphor Liniment (Camphorated Oil) (Composed Of Camphor, 200 parts; Cottonseed Oil, 800 parts). Dose, 10 to 30 drops. For external use chiefly. 4. Ceratum Camphorae. Camphor Cerate. (Composed of Camphor Liniment, White Wax, White Petrolatum, and Benzoinated Lard.) For external use. Action.—Camphor causes a local dilation of the capillaries of the skin, producing warmth, redness, and sometimes itching. Slight anesthesia follows. It causes smarting and hyperaemia of the mucosa, and if applied strong may cause considerable irritation. In this manner it has produced gastric ulceration. In small doses camphor warms the stomach, stimulates secretion, increases peristalsis, and expels flatus. Large doses may induce vomiting. Camphor is readily absorbed, both from application and inhalation. It is largely changed in the body and is eliminated in the urine as campho-glycuronic acid. In moderate doses camphor directly stimulates the heart-muscle, causing slower and stronger contractions and increased arterial pressure, but after large doses the pressure falls. Respiration is slightly stimulated by it, large doses causing slower and deeper breathing. In general it may be said that small doses of camphor stimulate, while large quantities depress, or even paralyze. This is true of all the functions it affects. The action of small doses upon the nervous system is to produce a feeling of slight exhilaration or contentment. Large doses excite the higher cerebral and medullary centers and then paralyze them; poisonous doses occasioning more or less of the following symptoms: esophageal and gastric pain, vomiting, headache, dizziness, mental confusion, drowsiness, delirium, and stupor; feeble, running, or intermittent pulse, cold skin, cold sweat, and muscular weakness followed by rigidity and epileptiform. convulsions, collapse and death. The type of convulsions shows its effects to be chiefly upon the cerebral cortex, though it acts also progressively on the medulla, causing death by respiratory paralysis. Camphor does not affect all persons alike. Some may pass directly into drowsiness, insensibility, and stupor, followed by death. If taken for long periods, even in moderate doses, camphor gives rise to a state of mental confusion. Opium and repeated small doses of alcohol are the best antagonists of the untoward effects of camphor. Therapy.—External. Camphor is stimulant, rubefacient, antipruritic, and feebly antiseptic. Owing to its agreeable odor and pleasant stimulating effects it is largely used, as a powder, in lotions, and ointments, or rubbed up with other solids to produce anodyne and antiseptic liquids. In this manner, when triturated with chloral hydrate, menthol, phenol, thymol, and similar bodies, ideal liquid antiseptics are obtained for use upon wounds, neuralgic and other painful areas. Powdered camphor is an ingredient of tooth powders and pastes and dusting powders for skin diseases. Alone or with zinc oxide, talc, or precipitated chalk it may be used upon bed-sores with decided relief. Such combinations are valuable in intertrigo, chronic eczema, urticaria, and zoster. Many snuffs contain powdered camphor, and it is useful to stimulate sluggish ulcers. Sprinkled upon the face it is used to control itching and to prevent pitting in small-pox. The spirit is a household embrocation for the relief of pain and itching, and it is used largely, alone, or in liniments and embrocations, for the relief of pain, stiffness, soreness and swelling, as in myalgia, facial and other neuralgias, and upon rheumatic joints, deep inflammations, chronic indurated glands and other indurations, sprains, contusions, and inflammatory swellings. An ethereal tincture of camphor is said to give relief in erysipelas. Inhaling the spirit, or camphor dropped into hot water, gives relief in nervous headache, and often aborts acute colds, coryza, and influenza, giving respite from the excessive secretion and the accompanying headache. A solution of camphor in liquid petrolatum (usually with menthol) is a popular spray for similar uses, and for laryngitis, pharyngitis, chronic nasal catarrh and hypertrophic rhinitis. The spirit, the liniment, or camphorated oil are favorite applications for tenderness and pain, chilblains, toothache, and acute mastitis: in the latter it tends to suppress the milk. The spirit is in common use as a lotion for headache in nervous individuals with feeble circulation, and tendency to fainting. The oil, by injection, is sometimes effectual in removing seatworms. So-called “camphor-ice” is a soothing, camphorated petrolatum preparation for labial herpes. Internal. Camphor is used to allay nervous excitement, subdue pain, arrest spasm, and sometimes to induce sleep. It is an important remedy in many disorders of neurotic women and children, being frequently most effective as a nerve sedative, antispasmodic, and carminative in nervous nausea and vomiting, flatulence, hiccough, and tendency to spasms or fainting. It is especially serviceable in palpitation of the heart due to gaseous distention of the stomach, or to nervous irritability. In occipital headache, from mental strain, or overstudy, small doses of 1

CAPSICUM
   The ripe fruit, dried, of Capsicum frutescens, Linné (Nat. Ord. Solanaceae). Tropical America; also cultivated in most tropical countries. Dose, 1 to 2 grains. Common Names: Cayenne Pepper, Guinea Pepper, Red Pepper, African Chillies, Bird Pepper. Principal Constituents.—Fixed oil, resin, fats, and the rubefacient and acrid principle capsaicin (C9H14NO2) and a volatile oil, capsicin. Preparations.—1. Specific Medicine Capsicum. Dose, 1/10 to 2 drops, very largely diluted. 2. Tinctura Capsici, Tincture of Capsicum. Dose, 1/10 to 10 minims. 3. Emplastrum Capsici. Capsicum Plaster (Composed of Oleoresin of Capsicum and Rubber Plaster). Rubefacient. Specific Indications.—Marked depression and debility, with feeble pulse and repressed secretions; pale membranes with scanty, viscous secretion; tongue dry, harsh, and mouth and salivary secretions suppressed or scanty; atonic dyspepsia of drunkards; alcoholic delirium of the depressive type; congestive chill; colic, with abdominal distention; debility with faulty gastro-intestinal functioning in the aged. Action.—Locally capsicum is decidedly irritant, causing dermal heat and redness. It does not vesicate, however, unless long and closely applied to the mucosa. The oleoresin is much more active and causes sharp burning pain and may destroy the epidermis. Capsicum is a pure, energetic and permanent stimulant. In large doses it produces vomiting, purging, pains in the stomach and bowels, gastro-enteritis, giddiness, strangury, and a species of intoxication and enfeeblement of nerve power. Smaller doses give warmth to the stomach and excite a hyperaemic state of the gastric mucosa, with increased secretion and accelerated movement of the musculature of the stomach and bowels. It slightly increases the urine, and is mostly eliminated by the kidneys. Therapy.—External. Tincture of Capsicum is an important topical stimulant, rubefacient and counter-irritant. By its revulsive action it often relieves local pain. Painted upon chilblains it quickly gives relief. The pure tincture alone, or mixed with glycerin or mucilage of acacia, may be used. Applied to an aching tooth it either relieves or aggravates, according to the sensitiveness of the nerve or the degree of inflammation present. We have used it with great satisfaction for pain coursing along the spermatic cord in the lower quadrant of the abdomen. It must not, however, be allowed to come in contact with the tender skin of the scrotum. The tincture has been painted upon the scalp to excite the growth of hair in alopecia. With or without glycerin or mucilage of acacia it may be used to clear up ecchymoses. Dry capsicum in the shoes was one of Scudder's favorite means of warming cold feet. Diluted tincture of capsicum, or capsicum with vinegar, and sometimes with salt, is a common and useful stimulating gargle for sluggish forms of sore throat, and sometimes apparently aborts tonsillitis. Capsicum may be used for many of the revulsant effects required of mustard. It does not blister nor cause strangury when so applied. Either the tincture painted upon the part or the capsicum plaster may give relief to so-called chronic rheumatic pains, and be applied in lumbago, pleurodynia and intercostal neuralgia. A stupe of hot water and capsicum applied to the nape of the neck sometimes relieves the headache of debility. Internal. Capsicum is a pure stimulant to the heart and circulation, giving increased force and slightly augmented frequency to the pulse. One thoroughly acquainted with the action of capsicum can scarcely comprehend why physicians seek for habit-forming stimulants which do infinite harm when so simple and efficacious and pure a stimulant as capsicum may be had. Used within proper dosage it can scarcely do harm, and generally results in incalculable good. Not merely for temporary purposes is capsicum efficient, but its effects are more or less permanent. Naturally it should be selected for atonic conditions and avoided where irritation or active inflammation is present. Nevertheless, in low grades of inflammation and fever, with sluggish blood current, it is a most efficient and necessary stimulant when given in small doses. The infusion of capsicum is a simple domestic remedy for acute colds, sore throat and hoarseness. Small doses of the tincture are of the utmost value in debility with deficient gastric action. When the membranes are pale, relaxed or flabby, and secretion is impaired or scanty and viscous, capsicum will do more than any other agent to rectify the condition and prepare the way for the action of other medicines. Even where the tongue is dry and elongated and parched from lack of secretion, and the glands of the mouth are inactive, no agent is superior nor safer than capsicum. It has, therefore, wide usefulness in disease-acute, subacute, or chronic. For chronic gastric catarrh it may be used occasionally, but should not be long continued lest it increase the malady sought to be improved. It is invaluable in some cases of atonic dyspepsia, with deficient secretion. It is often promptly effective in gastric flatulence, and is an agent of great value to prevent the accumulation of gases in both stomach and intestines. A mixture of capsicum, vinegar, and salt will sometimes prove a good antiemetic if given in small doses diluted with cold water. Capsicum should be largely used in low forms of fever-the more depressed the type the more it is needed. It is then of great advantage to maintain the equilibrium of the secretions and the circulation. Capsicum stimulates the appetite, aids digestion, facilitates peristalsis, and is, therefore, both stimulant and tonic to the gastro-intestinal tract. It thus maintains the integrity of those functions-an important desideratum during fevers and in convalescence therefrom. In grave cases of typhoid fever, with almost complete suppression of natural secretions, we would be at a loss without capsicum. It sometimes checks a congestive chill, and1

CAULOPHYLLUM
   The rhizome and roots of Caulophyllum thalictroides (Linné, Michaux (Nat. Ord. Berberidaceae). In rich woods in the eastern half of the United States. Common Names: Blue Cohosh, Squaw-root, Pappoose-root. Principal Constituents.—An indifferent alkaloid caulophylline (not to be confused with the resinoid "caulophyllin,") and an active glucoside of the saponin type, leontin. Preparations.—1. Specific Medicine Caulophyllum. Dose, 1 to 10 drops. 2. Leontin (Lloyd's) , a 1 per cent solution of leontin, the emmenagogue principle of caulophyllum. Dose, 5 to 15 drops in syrup or sweetened water. 3. Syrupus Mitchellae Compositus, Compound Syrup of Mitchella (Compound Syrup of Partridge berry). Dose, 1-4 fluidounces. Specific Indications.—Uterine pain with weight and fullness and pains in the legs; sense of pelvic congestion; sluggish labor pains; as a partus praeparator. Action and Therapy.—Caulophyllum was at one time largely used as an antispasmodic, emmenagogue, parturient, diuretic, diaphoretic and expectorant, all of which properties it possesses in greater or less degree, according to its manner of use. It unquestionably acts with some force upon the reproductive organs of women, overcoming pain and tenderness in debilitated subjects. It seems best adapted to uterine debility arising from chronic inflammatory conditions. In many respects it resembles macrotys (cimicifuga), both upon the reproductive organs and in controlling rheumatoid pain. For many years it was a favorite remedy for false pains and afterpains. It, like macrotys, facilitates child-birth. Both agents produce contractions most like those of the natural labor process. In this respect they were often used to replace tetanic-acting ergot when that agent was so popular and so damaging as an oxytocic. It may be used to assist labor when delay is due to weakness, fatigue, or lack of uterine power, or when the tissues feel full, as if congested. The skillful use of forceps has largely supplanted drugs of this type, yet there are many cases in which they might still be used with greater safety than forceps. As an ingredient of the Compound Syrup of Mitchella (Mother's Cordial), it is still relied upon by some physicians as a good partus praeparator. Caulophyllum is a good emmenagogue. It may be used where there is congestion with irritation, and the natural functions are badly performed. In troubles dependent upon such irregularities, it has given fair results, though macrotys has supplanted it for most conditions. Metritis, endo-metritis, amenorrhea, dysmenorrhea, ovaralgia, ovaritis, rheumatism of the uterus, menstrual cramps, uterine subinvolution, and spasmodic retention of urine have all been favorably influenced by caulophyllum. It is of some, though minor, value in spasmodic urinary and gastro-intestinal disorders. Leontin (1 per cent solution of the emmenagogue principle of caulophyllum) has been successfully prescribed for amenorrhea, dysmenorrhea, and chlorosis. The dose of leontin is 5 to 15 drops in syrup or sweetened water. Compound Syrup of Mitchella may be given for weeks as a uterine tonic preceding labor. It seems to have both a real and a psychic influence that will redound to the benefit of the prospective mother. It is also a good uterine tonic for debility and uterine feebleness in the childless, and assists in the recuperation of strength and rapid involution of the womb following labor. The dose of the syrup is from 2 fluidrachms to 1/2 fluidounce, 2 or 3 times a day.1

COLCHICUMCOLCH
   The dried (I) root and (II) seed of Colchicum autumnale, Linné (Nat. Ord. Liliaceae.) England and other parts of Europe. Dose, Corm, 1 to 5 grains; seed, 1 to 5 grains. Common Names.-I. Colchicum Corm (Colchici Cormus); II. Colchicum Seed (Colchici Semen). Principal Constituent.—The powerful alkaloid Colchicine (see below.) Derivative.—Colchicina, Colchicine. A very toxic alkaloid occurring as pale yellow scales or powder, practically odorless. It should not be tasted. Soluble in water. The salicylate is sometimes employed. Dose, 1/300 to 1/100 grain. Preparation.—Specific Medicine Colchicum. Dose, 1 to 10 drops. Specific Indications.-Acute gout; rheumatism, without much fever, occurring in gouty individuals; tearing pain, aggravated by heat. Action and Toxicology.—Upon the skin and mucosa colchicum is irritant, causing smarting and redness, sneezing and conjunctival hyperemia. Small doses increase the secretions of the skin, kidneys, liver, and bowels. Large doses are dangerous, producing gastric discomfort, nausea and vomiting and purging, and violent peristalsis with much intestinal gurgling. Poisonous doses produce a violent gastro-enteric irritation, with symptoms much like those of choleraagonizing griping, painful muscular cramps in the legs and feet, large but not bloody evacuations of heavy mucus and serum, thready pulse, collapse, and death. Toxic doses are almost sure to kill in spite of efforts to save life, the patient dying a slow, painful, and agonizing death, the final act of which is respiratory paralysis. Consciousness remains to the end. The reputed antidote is tannin freely administered with plenty of water and followed by the use of emetics or the stomach pump. Opium may be given to relieve pain, atropine to sustain breathing, and artificial heat to maintain bodily warmth. Therapy.—Colchicum is an extremely dangerous medicine and should be used with the greatest of caution. It is the remedy for acute gout, temporarily giving quick relief if administered short of purgation. For some unknown reason attacks recur more frequently when colchicum has been used, though it almost magically relieves the paroxysms. It is useful for disorders depending upon a gouty diathesis, though it is less effectual in chronic gout than in the acute form. In rheumatism, pure and simple, it usually has little or no value, though we have had excellent results after failure with the usual antirheumatics, in cases where pain persisted in one part for longer periods than usual, in acute articular rheumatism with but little fever. These cases resembled gonorrheal arthritis and were accompanied by a leucorrheal discharge, but were not gonococcic. In most cases the fingers, wrists, and abdomen were the most painful locations. Some have advised it in socalled chronic rheumatism when the patient is known to have occasional gouty attacks. We have seen it do good in rheumatoid arthritis; a condition much more prevalent in this country than genuine gout, a disease rarely encountered in America. In rheumatoid headache and in rheumatic iritis colchicum is sometimes of value when occurring in one with swollen joints, with or without effusion, and attended by tearing, muscular pain, aggravated by heat. Subacute and chronic sciatica are asserted to have been relieved by colchicum when the pain is sharp, shooting, tearing, or dull, from back to hips and down the legs, fever being absent. In rheumatic conditions colchicine salicylate in doses of the 1/128 grain is often more serviceable than colchicum.1

COLLINSONIA
   The fresh root and plant of Collinsonia canadensis, Linné (Nat. Ord. Labiatae.) Damp and rich soils of woods from Canada to Florida. Common Names: Stone-root, Rich-weed, Horse-balm, etc. Principal Constituents.—Resins and volatile oil. Preparations.—1. Specific Medicine Collinsonia. Dose, 1/10 to 30 drops. 2. Aromatic Collinsonia (prepared from the plant). Dose, 1 to 30 drops. Specific Indications.—Irritation, with a sense of constriction in the larynx, pharynx or anus; sense of constriction with tickling in the throat, with cough arising from use of the voice; a sensation as if a foreign body were lodged in the rectum, with a painful contraction of the sphincter and perineum; sense of contraction in the rectum, with constipation due to vascular engorgement of the pelvic viscera; scybalous feces; sticking pains in the heart, larynx or bladder; contracted abdomen; vesical tenesmus; hemorrhoids; varicocele; follicular tonsillitis, with chronic hypertrophy of the faucial glands; any condition with weight and constriction, with or without heat. Action.—Collinsonia affects chiefly the venous system and the mucous membranes, particularly the hemorrhoidal venous circulation. It also stimulates the vagi, relieving irritation of the parts to which they are distributed, and is believed to strengthen the action of the heart. Small doses of the green root produce emesis, and sensible doses of the fluid preparations cause an increase in urine and slightly that of the skin. Therapy.—Collinsonia is a remedy for venous stasis and for irritation of the mucosa. Chiefly it meets one prime condition and the many disorders dependent thereon. This is atony of the venous circulation, whether due to relaxation of the blood vessels or to lack of tone in the venous side of the heart. Therefore its best results are obtained in conditions showing feeble or sluggish venous and capillary flow. Under these conditions it specifically improves impairment of the mucous membranes, appearing to be most active in disorders of the throat and rectum, though venous stasis in any organ or part is corrected by it. Collinsonia is the most effective medicine we have for that form of laryngitis known as “minister's sore throat”—a hyperaemic or congestive state, with tenderness, hoarseness, and cough brought on by intensive speaking or singing. It is common among public speakers, singers, auctioneers, hucksters, and others compelled to use the voice beyond the ordinary. It is also valuable in other forms of laryngitis, with congestion or hyperaemia of the vocal apparatus, in chronic bronchitis, pharyngitis, tracheitis, and aphonia, all depending upon irritation associated with venous debility. Rx. Specific Medicine Collinsonia, 2 fluidrachms to 1 fluidounce; Simple Syrup, to make 4 fluidounces. Mix. Sig.: One teaspoonful every 3 or 4 hours. Foltz advised it in the early stage of middle ear disorders, with free nonpurulent secretions, and when complicated by follicular pharyngitis and hypertrophied Luschka's glands. For many of the throat disorders Aromatic Collinsonia is preferred by some prescribers. The second great use for collinsonia is in rectal venous debility. Here the smaller doses are more effectual. In hemorrhoids it usually does not cure, though it may do so early in their course. It is to be used when there is vascular engorgement of the pelvic viscera, with a sense as if a foreign body were lodged in the rectum, causing constant uneasiness and affecting the nervous system profoundly. There is weight, heat, and dull pain, with or without scybalous constipation, or sometimes with partly semifluid and partly scybalous feces. The only rational procedure is to have the disturbing hemorrhoids surgically removed, but if this cannot be done, or the patient will not consent, then recourse to collinsonia will give us much relief as can be obtained from any safe medicine. Collinsonia relieves, to a lesser extent, subacute proctitis, the tenesmus of mild types of dysentery and diarrhoea and rectal pain following operations, as well as that of fissures, fistulae, and allied conditions, though much reliance cannot be placed upon it for any of these conditions, except in the hemorrhoids of the type described. It does, however, relieve discomfort in the rectum without apparent lesion other than that of vascular engorgement. Many value collinsonia in gastro-intestinal irritation with torpor of the portal circulation, irritation of the mucous membranes, and loss of appetite. Indigestion, spasmodic pain, gastric catarrh, and irritative dyspepsia, all with more or less constipation, appear to be benefited by collinsonia. By increasing innervation and relieving irritability it proves useful in atonic dyspepsia, with poor abdominal circulation. Irritation of parts supplied by the vagi is relieved by small doses of collinsonia. Thus it ameliorates some cases of asthma, chronic cough, and the cough attendant upon disorders of the heart. Some value it in mitral regurgitation and in rheumatism of the heart. In all conditions the dilated capillaries showing passive engorgement will guide to its use. It was formerly regarded a remedy for gravel, but is little valued for that purpose now further than to relieve irritation and discomfort when gravel gives rise to pelvic vascular debility. Cases of varix of the vulva have been reported as modified, but not cured by it; the same is true of varicocele and varicose veins of the legs. In whatever disorder collinsonia is helpful, there is always a sense of weight and constriction, venous engorgement, dilated capillaries, and muscular atony.1
