    Elaterinum.  Elaterin, C20H28O5, U.S.P.
    Ecballium Elaterium, (Linne') A. Richard.  A substance obtained from the juice of the fruit.
    Habitat.  W. Asia, N. Africa, S. Europe -- Mediterranean Basin, dry waste places;  cultivated.
    Syn.  Squirting or Wild Cucumber, Wild Balsam Apple; Fr. Concombre sauvage,  Elaterine, Elatine; Ger. Eselsgurke, Springgurke, Elaterin.
    Ec-bal'li-um.  L. fr. Gr. ek, out, + ... , to throw -- i.e., the fruit expelling its contents  when fully ripe.
    El-a-te'ri-um.  L. fr. Gr...., driving out, , purging -- i.e., its medicinal property.  El-a-te- ri'num, Elat'er-in -- both simply derivative names.
    PLANT. -- Common perennial, squash-like vine; stem trailing, tendril-bearing, succulent, bristly, .6-1.3 M. (2-4 degrees) long; leaves cordate, 7.5-12.5 Cm. (3-5') long, lobed, hispid, pale green; flowers monoecious, yellow; fruit 5 Cm. (2') long, 2.5 Cm. (1') broad, oblong, pale yellowish-green, beset with fleshy prickles, 3-celled, containing bitter, watery, mucilaginous juice in which are many light brown seed.
    CONSTITUENTS. -- Elaterin 44 p.c., green resin 17 p.c., starch 6 p.c.; prophetin, ecballin (elateric acid), hydroelaterin, elaterid.
    Elaterinum.  Elaterin. -- Obtained by exhausting elaterium (a substance deposited by the juice of the fruit) with hot alcohol and precipitating with water, or treating with hot chloroform and precipitating with ether, washing with ether and recrystallizing from alcohol or chloroform.  It is in minute, white, hexagonal scales, prismatic crystals; odorless; slightly acrid, bitter taste, permanent, soluble in alcohol (325), boiling alcohol (100), chloroform (15.5), ether 450, benzene (310); insoluble in water; alcoholic solution neutral.   Tests: 1.  Solution of .01 Gm. in 5 cc. of melted phenol, + a few drops of sulphuric acid -- crimson, rapidly changing to scarlet; incinerate -- ash negligible.  2.  Shake .1 Gm. With distilled water 9 cc. + diluted hydrochloric acid 1 cc.; to separate portions of filtrate add .5 cc. mercuric potassium iodide T.S., or iodine T.S.--no turbidity (abs. of alkaloids).  Impurities: Alkaloids, readily carbonizable substances.  Dose, gr. 1/20-1/10 (.003-.006 Gm.).
    ADULTERATIONS. -- ELATERIUM: Starch, calcium carbonate, various minerals colored green.  Owing to this adulteration and the irregular treatment in collecting and curing, it becomes a very uncertain product, hence the official Elaterin is much to be preferred, which as a rule is pure.
    Commercial. -- Fruit when ripe is yellow and falls to the ground from its attachment, and at the instant of separation the entire contents are expelled violently (hence called squirting cucumber), through the socket or peduncle orifice -- due to osmosis from pericarp to central pulp, causing engorgement, therefore tension and rupture at weakest point.  Elaterium should be prepared from the fruit collected with the stalk, just before ripe, cutting fruit lengthwise, lightly pressing (best without pressure), straining, the juice, setting aside to deposit, and putting this (sediment) on porous tiles to dry by gentle heat, avoiding exposure to the sun.  Forty cucumbers without pressure yield 6 gr. (.4 Gm.), and 40 pounds (18 Kg.) yield only 240 gr. (15.5 Gm.).  Elaterium occurs in grayish fragments or scales, odor tea-like, taste bitter, acrid; should not effervesce with hydrochloric acid.  Dr. Clutterbuck's is considered best.
    PREPARATIONS. -- (Unoff.)  ELATERIN: Trituration, 10 p.c., gr. 1/2-3/4 (.03-.05 Gm.).  Pulvis Elaterini Compositus, 2.5 p.c., gr. 1-4 (.06-.26 Gm.).  ELATERIUM, dose, gr. 1/8-1/4 (.008-.016 Gm.).  Solution of Elaterium, 1/4 p.c., in alcohol + ½ p.c. nitric acid, dose, mxxx (2cc.).
    PROPERTIES. -- Hydragogue cathartic (most powerful known), producing profuse watery evacuations with griping and much prostration; large doses nauseate, vomit, inflame stomach and bowels, increase flow of urine, and may kill.  Does not vomit nor purge dogs, rabbits, but kills them by convulsions.  Those working in it often have ulcerated fingers, eyes, etc.
    USES. -- The fruit was employed by the ancients, being recommended by Dioscorides in mania, melancholia.  Sydenham used it in dropsy, but it fell into disfavor through its severity, until brought forward again by Dr. Ferriar.  Useful in dropsy, Bright's disease with dropsy (as it is believed to eliminate more urea through the bowels than any other cathartic), brain and lung congestion, uremia, but never in heart disease.
    Poisoning.: Same as for aloe, etc.  Evacuate stomach, give demulcents, opium, stimulants.


    Brauner'ia pal'lida, or B. Angustifu'lia, Echinacea, Pale purple Cone-flower, N.F. -- The dried rhizome and roots with not more than 3 p.c. of foreign organic matter; S.

    ADULTERATIONS. -- SEED: Rare -- those of various varieties and allied species taken from the pericarp; ENTIRE FRUIT -- with orange seed, green coffee, etc.; POWDER: Starch, sodium carbonate, ginger (recognized by its larger starch grains), etc.
    Commercial. -- Plant grows wild but mostly by cultivation in Malabar (W. Mysore) and Ceylon, on spaces cleared in mountain forests affording shade, or on betel-nut plantations, and yields the fourth year and many thereafter.  Fruit is gathered mostly in dry weather, Oct.-Dec., preferably prior to maturity to minimize splitting, then dried artificially on tiers of trays in curing houses (brownish), or better in the sun, guarding against rain and excessive heat exposure, that cause the moist seed to swell and rupture pericarp (yellowish); the slower the drying, the less the splitting.  Bleaching is effected by exposing to sulphur fumes, or to dew and sunlight, the finest by washing with alternating solutions of lathery soap-berry and astringent acacia pods, finally drying in the sun.  Value is determined by size, color, plumpness, smoothness (the best being creamy white, smooth, silky) and are assorted through sieves into 4 kinds: (a) Shorts, 12 Mm. (1/2') long, 6 Mm. (1/4') broad, plump, heavy; (b) Mediums, 18-25 Mm. (3/4-1') long, 6 Mm. (1/4') broad, paler buff, finer ribbed; (c) Longs, 25-31 Mm. (1-1 1/4') long, 4 Mm. (1/6') broad, rarely imported; (d) Tiny, least desirable.  There are several varieties: 1, Mysore (Ceylon-Mysore, Alleppi), shorts, best, bleached and unbleached (greenish), exported from Alleppi, Calicut; 2, Malabar, shorts, mediums, high grade, preferred by some, exported from Ceylon, India (Bombay), brown, striated; 3, Madras, usually mediums, pale buff, exported from Madras, Pondicherry; 4, Mangalore; 5, Ceylon Mangalores, round valuable.  The Ceylons are the wild-grown fruits of Ceylon, and the Siam of Cochin, Annam, Tonquin (Tonking) combined; the shorts of all varieties are best and most desired; imported in chests, 60-100-200 pounds (27-46-91 Kg.).  The shelled seed, deteriorating rapidly, should never be used.
    CONSTITUENTS. -- Volatile oil 5 p.c., fixed oil 10 p.c., potassium salts 2.5 p.c., starch 3 p.c., nitrogenous mucilage 1.8 p.c., yellow coloring matter .4 p.c., ligneous fiber 77.3 p.c., manganese .8 p.c., ash 6-8-15 p.c.
    Oleum Cardamomi, N.F. -- This volatile oil (mostly in the testa) distilled from the seed, is a colorless, pale yellow liquid, characteristic, aromatic, penetrating, somewhat camphoraceous odor of cardamom, and persistent, pungent, strongly aromatic taste; soluble in alcohol, 70 p.c. alcohol (4), sp. Gr. 0.935, dextrorotatory; contains terpinene, C10H16, possibly dipentene, a body of the composition C10H18O (terpineol?), acetic and formic acids; also extracted by ether, giving a more durable oil mixed with fixed oil, this latter being easily separated.  The distilled oil readily deteriorates, and should be kept cool, dark, in small well-stoppered, amber-colored bottles.

    PLANT. -- Rye: culm 1.5-2 M. (5-6 degrees) high; leaves .25-.5 M. (10-20') long, upper surface rough; spike 10-15 Cm. (4-6') long, 2-sided, 2-flowered spikelet, June; fruit July; seed (grain) oblong, grooved on upper side, hairy at summit, brownish.  SCLEROTIUM (ergot), cylindraceous, obscurely 3-angled, fusiform, obtuse, somewhat curved, 1-4.5 Cm. (2/5-1 4/5') long, 3-5 Mm. (1/8-1/5') thick, purplish-black, longitudinally furrowed; fracture short, white, tinged with purple or gray; odor characteristic but free from mustiness of rancidity; taste oily, somewhat acrid, disagreeable.  POWDER, grayish-brown -- purplish and whitish fragments of outer tissue and thin-walled cells.  Tests: 1. Shake 1 Gm., for 5 minutes in a closed flask, with ether 20 cc. + 15 drops of 20 p.c. sulphuric acid, shake filtrate thoroughly with 15 drops of cold saturated sodium bicarbonate solution, the separated lower aqueous layer -- red or violet (pres. Of sclererythrin).  2. Hot water added to crushed or powdered -- no rancid or ammoniacal odor.
    Ergot that breaks with a sharp snap, devoid of pinkish fracture, hard, brittle between the teeth, odorless and tasteless, should be rejected.  Should be dried at a low temperature, and as it deteriorates with age should not be kept longer than one year.  Solvent: diluted alcohol.  Dose, gr. 15-60 (1-4 Gm.).
    Commercial. -- Rye is to Russia what corn is to America, its bread approximating nearer that of wheat than any other grain.  The origin of the sclerotium is the biennial thallophyte (fungus) Claviceps purpurea, parasitic during moist seasons on the ovary of grains, grasses, sedges -- Carex, Cyperus species, etc., (that of rye alone being collected for medicine), -- the development having three stages: 1, Mycelial -- when blooming a few ovaries in some grain heads become covered with sweet, yellow mucus, honey-dew of rye, whose disagreeable odor repels bees, but attracts ants, beetles, and flies -- the once supposed cause of the diseased grain, but now known only to aid its dissemination and thereby the spreading of the disease; the filamentous cells (hyphae), collectively forming the mycelium, spread over the lower portion of the ovary and cause decomposition of ovarian tissue, production of honey-dew (sugar), and innumerable reproductive bodies (conidia) imbedded therein; 2, sclerotial -- when this conidial formation is at its height the mycelium ceases its superficial gowth, presses into the ovary and begine to form a denser tissue at its base and central portion, and, growing upward, horn-like body, sclerotium (official ergot) -- the dormant or resting form of the fungus; 3, thalloidic -- when in the following spring ergot sprouts in many heads (stromata), consuming its fixed oil and other constituents, and becoming shriveled and worthless; have formed upon the head's surface spherical-topped excrescences, size of small pin's head, containing the orifices of flask-shaped cavities (conceptacles, perithecia) from whose base many cells (spore-sacs, asci) arise, each containing 8 filiform spores formed synchronous with rye flowers, so that the two (spores, flowers) acting together develop again the sphacelia (sclerotium), hence the necessity of using fresh ergot in medicine, at the end of the second stage, prior to the beginning of the third.
    Ergot must be dried (too much causing injury, too little moldiness) and stored (very dry, in well-stoppered bottles) with great care, as the fixed oil soon inclines to become rancid, and a mite ofttimes will attack it, in either case rendering the product worthless.  This deterioration may be prevented largely by either (1) deoleation -- extracting fixed oil with ether or petroleum benzin, drying (2) adding occasionally a few drops of chloroform to the closed container, (3) suspending in the container a tube of potassium sulphate saturated with formaldehyde, (4) keeping over unslaked lime, (5) coating with ethereal solution of Tolu or (6) mixing powdered drug with benzoin (5 pc.); in any event only the preservation of the sclerotium (entire) can be relied upon.  There are three varieties: 1, Spanish, largest, finest-looking, highest-priced, bluest; 2, Russian, reddish-purple, considered most active; 3, German, reddish-purple.
    CONSTITUENTS. -- Alkaloids .38-.6 p.c.: Ergotoxine, Parahydroxyphenylethylamine (Tyramine), Histamine, Isoamylamine, Ergamine, Enzymes (2).  Fixed oil 30 p.c., sclererythrin (coloring matter), scleromucin (mucilage); ergotininic acid, clavine, ergotinine, all three more or less inactive; ash 5 p.c.  Such names as cornutine, sphacelotoxine, ergotinic acid, etc., only represent indefinite substances and should be abandoned.
    Ergotoxins. -- This, the essential active constituent, produces the true therapeutic effect of ergot (bluing of the cock's comb, contracting uterus, etc.): it is amorphous, but forms crystalline salts, phosphate,  sulphate, tartrate, suitable for hypodermic injection; its presence in the other constituents often contribute its marked properties; action may largely be due to the amino group, in which fresh ergot is richest -- just before rye is ripe.
    Para-hydroxyphenylethylamine (Tyramine). -- This and other amines (ammonia from putrefaction) may stimulate the uterine muscular wall (nerve-endings) and raise blood pressure, while histamine stimulates uterine action, but lowers decidedly blood pressure, both serve chiefly as synergists to the action of ergotoxcine.
    Enzymes. -- These (one diastasic, the other hydrolyzing fats) rapidly deteriorate and reduce the physiological activity of ergot that has been dried slowly and imperfectly, forming a rancid, fatty odor (tramethylamine); both enzymes lose hydrolytic power by prolonged keeping or complete drying of the ergot, hence the necessity of proper care in this process.
    Fixed Oil. -- This is a dark brown liquid containing eleic acid 68 p.c., oxyoleic acid 22 p.c., palmitic acid 5 p.c., sp. gr. 0.925, and when removed by ether or petroleum benzin the ergot retains full alkaloidal strength which remains unimpaired for years if kept with care.
    PREPARATIONS. -- 1. Fluidextractum Ergotae, Fluidextract of Ergot.  (Syn., Fldext. Ergot., Fluid Extract of Ergot; Br. Extractum Ergotae Liquidum; F. Extrait fluide d'Ergot de Seigle; Ger. Extractum Secalis cornuti fluidum, Mutterkornfluidextrakt.)
    Manufacture: Percolate 100 Gm., with sufficient purified petroleum benzin to remove fixed oil, discard benzin percolate; remove ergot from percolator, expose it to air, when dry moisten with sufficient 1st menstruum (diluted alcohol 98 cc. + hydrochloric acid 2) to keep damp while macerating 6 hours in a tightly covered container, pack in percolator, add remainder of 1st menstruum, then 2d menstruum (diluted alcohol) to saturate and cover; macerate 48 hours, percolate with 2d menstruum until exhausted; reserve first 85 cc., reclaim alcohol from remainder, concentrate residue at 60 degrees C. (140 degrees F.) to soft extract, which dissolve in the reserved portion, mix thoroughly, add 2d menstruum q.s. 100 cc.  When administered by intramuscular injections to single-comb, white Leghorn cocks, in doses of .5 cc. for each Kg. Of body weight of cock--the comb becomes darkened in degree as by same dose of standard fluidextract; contains alcohol 37-42 p.c.  Dose, mxv-60 (1-4 cc.).
    2.  Extractum Ergotae Aquorum, Ergotine, N.F. -- Ergot 200 Gm., chloroform water q.s. to exhaust, evaporate to 100 cc., cool, add alcohol 100, evaporate to pilular consistence.  Dose, gr. 1-5 (.06-.3 Gm.) + water, hypodermically.
    Unoff. Preps.: Emmenagogue, ecbolic, parturient, astringent, hemostatic, excitomotor, poisonous.  Value depends upon (1) bluing (gangrene) of the cock's comb. (2) contracting the uterus, (3) raising the blood pressure: contracts all unstriped (involuntary) muscle, especially uterus and intestine, expelling their contents.  Depresses heart muscle, hence slows pulse, contracts arterioles (hemostatic), thus increasing arterial pressure; diminishes sweat, saliva, milk, urine.  In large doses gastro-intestinal irritant, causes nausea, vomiting, colic, thirst, purging, convulsions, "acute ergotism," or by many small doses may have "chronic ergotism:' this last may be in two forms: 1. Convulsive, causing tetanoid spasms of the flexors, respiratory muscles, death by asphyxia.  2.  Gangrenous, causing cold, numb limbs, loss of sensibility, gangrene of lower extremities, buttocks, etc., epileptic convulsions, coma, death.
    USES. -- In labor to increase the power and duration of uterine contractions--tetanic spasm; these are continuous while natural labor-pains are intermittent, hence ergot is dangerous in thoughtless hands.  Should never be used until after head is born, when it simply promotes firm uterine contraction; it is still wiser to withhold it until after birth, to prevent postpartum hemorrhage and aid uterine contraction (fluidextract 3j (4cc.) by mouth, or better, hypodermically.  A small dose (one-third) often controls uterine inertia in labor, where nerve-stimulants (coffee, strychnine, etc.) fail; this does not bring on constant tetanic contraction, but simply the "to-and-fro" movements.  Effect lasts half an hour, being felt in 15 minutes, and should be repeated every 15 minutes until action manifest.  Used also in epistaxis, night-sweats, dysentery (bloody), diarrhea (serous), hemorrhoids (bleeding), chronic metritis, dysmenorrhea, menorrhagia, fibroids polypi, plethoric amenorrhea, atonic spermatorrhea, atonic arterial hemorrhage (males and females), spinal congestions, splenic enlargement, lax sphincters, incontinence of urine, aneurisms, diabetes.  Externally to hemorrhoids.
    For hypodermic injection -- employ "Ergot Aseptic," or "Ergone," or solid extract deprived of alcohol and dissolved in water -- introduce near seat of trouble; results here much better than by mouth; should have bladder and bowels freely open.  The ergot formed on grasses is often sufficient to cause grazing animals to abort, and flour made of grain containing much of it will also sometimes act medicinally.
    Poisoning: Have gastric disturbance, vomiting, diarrhea, thirst, burning pain in feet, tingling in fingers, cramps in extremities, dilated pupils, cold surface, dizziness, small and feeble pulse, convulsions.  Evacuate stomach (pump, emetics, purgatives), use tannic acid, stimulants, amyl nitrite (inhallation), strychnine, digitalis, friction, hot baths.
    Incompatibles: Cardiac and motor depressants (aconite, veratrum, lobelia, etc.), caustic alkalies, metallic salts.
    Synergists: Digitalis, belladonna (circulation), strychnine (nerves), ustilago, cotton root bark, hydrastine, emmenagogues.

    Commercial. -- Coca, although not introduced into England until 1870, was used in S. America prior to the Spanish conquest, 1569, by the aborigines, who extolled it as a God-given plant ("The Divine Plant of the Incas") that satisfied hunger, strengthened the weak, and banished man's misfortunes; but the invaders, intolerant of such homage, forbade its use and cultivation until they observed that it enabled the conquered to perform better work and service.  Previous to 1884 the alleged properties were thought legendary and imaginative, when, being considered simply a mild stimulant like tea, Koeler proclaimed its local anesthetic power.  Species differ when wild and under cultivation, and escaping this soon degenerate and show marked changes in leaf-characteristics.  It is cultivated extensively in the Andes on terraced plantations, cocales, cleared from the forests on the warm declivities, thriving best in a moist atmosphere and amid scattered trees, but not deep shade, which, as well as low elevation, develops bitterness, consequently any variation in this or in the prescribed soil, exposure and curing may affect quality.  Propagation is similar to our peach, yielding leaves the second year and continuing for fifty thereafter.  Leaves when bright green above and yellow-green below are picked carefully to avoid breaking, or injuring young leaf-buds that form the next crop, removed in baskets, spread on unroofed floors, and dried quickly for a few hours in the sun, if too rapidly losing odor and green color, if too slowly acquiring disagreeable odor and taste; after remaining 2-3 days in the coca-house, in loose piles, they are exposed again for a short time to the sun, to drive off developed sweat, and then compressed into bales (cestos), 25-50 pounds; 11.6-23.3 Kg., or better, tin-lined boxes that prevent likely deterioration in shipping through fermentative decomposition.  Irrespective of the care in drying and keeping impairment begins at once, cocaine decreasing materially, especially in dampness, owing to which they should be discarded after a few months.  Although in some localities collection is almost continuous there are at least 2-3 yearly harvests, the September being best, the April next, each yielding when dried 60-80 pounds (27-37 Kg.) per acre; the annual production is about 80,000,000 pounds (37,383,177 Kg.), exported largely from Huanuco, Lima, Truxillo, etc. There are two varieties: 1, Huanuco (Cuzco--E. Coca, short-styled), after cities of S. Peru, has best aroma, most cocaine, and less isatrophyl-cocaine; grown mostly in Bolivia, S. Peru, thriving and yielding maximum product at 1,050-1,800 M. (3,500-6,000 degrees), in 18 degrees south, and inferior grades at lower elevations; the true Bolivian (E. Bolivia'num, long-styled) is prized most highly, has larger fruit, smaller leaves, and owing to home demand seldom is exported; 2, Truxillo (Trujillo--E. Truxillense, short-styled), leaves ovate-oblanceolate, 1.6-5 Cm. (2/3-2') long, one-half as broad, pale green, thin, brittle, usually much broken, smooth, shining, petiole short and stout, slight point at apex, entire, the two collenchyma lines underneath frequently incomplete or obsure; odor more tea-like than preceding; taste and numbing effect similar; powder pale green; grown more northward, thriving well at lower elevations and preferred by natives for chewing.  Java and India coca (E. Coca, var. Sprucea'num, long-styled, styles exceeding stamens) seems identical with this variety but owing to inferiority is not exported.
    CONSTITUENTS. -- Cocaine (1860) .5-1 p.c., cinnamyl-cocaine, truxilline (truxil-cocaine, isatrophyl-cocaine, cocamine), C19H23O4N -- all three upon hydrolysis yielding ecgonine and methyl alcohol; pseudotropine, ecgonine, coca-tannic acid, wax, volatile oil, ash 8-10 p.c.; hygrine (volatile aromatic liquid) is doubted by some, while cocainidine, probably isomeric with cocaine, but weaker, has not yet been studied thoroughly.
    Cocaina. Cocaine, C17H21O4N. -- This alkaloid, composed of methyl alcohol, benzoic acid, and ecgonine, into which it separates by heating with strong sulphuric acid, is obtained by moistening leaves with sodium hydroxide solution, treating with benzin (kerosene), from which the alkaloids and cocaine are precipitated (hygrine, etc., remaining in solution); cocaine may now be separated by filtering and expressing, and purified by crystallizing from alcohol.  It is in colorless crystals, white crystalline powder, odorless, permanent, soluble in water (600), hot water (270), alcohol 6.5), chloroform (.7), ether (3.5), olive oil (12), liquid petrolatum (30-50), very soluble in warm alcohol, melts at 97 degrees C. (207 degrees F.); forms salts (hydrochloride, nitrate, sulphate, etc.).  Dose, gr. 1/8-2 (.008-.13 Gm.).
    PREPARATIONS. -- 1.  Cocainae Hydrochloridum.  Cocaine Hydrochloride, C17H21O4NHCl.  (Syn., Cocain.  Hydrochl., Cocainum hydrochloricum, Cocaine Chloride, Cocainae Hydrochloras, Cocaine Hydrochlorate; Fr. Chlorhydrate de Cocaine; Ger. Cocainum hydrochloricum, Kokainhydrochlorid.)
    Manufacture: Dissolve pure alkaloid, cocaine, in alcoholic solution of hydrochloric acid, and allow anhydrous salt to crystallize.  It is in colorless, transparent crystals, lustrous leaflets, white, crystalline powder, permanent, odorless, soluble in water (.4), alcohol (3.2), warm alcohol (2), chloroform (12.5), glycerin, insoluble in ether; aqueous solution (1 in 20) neutral, levorotatory; melts at 183-191 degrees C. (362-376 degrees F.), the higher point indicating greater purity.  Tests: 1.  Aqueous solution (1 in 20) + silver nitrate T.S. -- white precipitate, insoluble in nitric acid.  2.  Aqueous solution (1 in 50) 5 cc. + 5 drops of chromium trioxide solution (1 in 20) -- yellow precipitate, redissolved on shaking; now add hydrochloric acid 1 cc. -- permanent orange crystalline precipitate.  3. Dissolve .5 Gm. in sulphuric acid 1 cc. -- not more than slight yellow tint (abs. of readily caronizable substances) -- add cautiously distilled water 2 cc. -- aromatic odor of methyl benzoate, on cooling -- crystals of benzoic acid separate; incinerate .5 Gm. -- ash negligible.  4. Aqueous solution (1 in 50) 5 cc. + N/1 sulphuric acid .3 cc. + N/10 potassium permanganate .1 cc. -- violet color does not disappear entirely in half hour (abs. of cinnymyl-cocaine).  Impurities: Cinnamyl-cocaine, isatropyl-cocaine, readily carbonizable substances.  This salt is dispensed generally under the name of cocaine in (hypodermic) solutions, 2-4-5-10 p.c.  Dose, gr. 1/8-2 (.008-.13 Gm.).

(.0013 Gm.).
    PROPERTIES. -- Cerebral stimulant, bitter tonic, diuretic, mydriatic, diaphoretic, anaphrodisiac, narcotic.  Locally, has little action upon the unbroken skin, but acts upon mucous membranes and subcutaneous tissue as anesthetic and analgesic, producing also its constitutional effects.  It increases digestion, respiration, heart action, temperature, arterial tension, and the irritability of the sensory nerves, followed by mental, moral, and muscular depression.  It anesthetizes the gastric mucous membrane, thereby temporarily deadening the sensations of hunger and thirst, which, however, seem all the greater as the effects wear off; the brain is stimulated by increasing the blood supply, producing wakefulness, a sense of hilarity and well-being (similar to cannabis), increased muscular strength and endurance.  Acts as a diuretic by checking waste processes, lessening the quantity of urea, but increases that of urine; dilates the pupil by stimulating the ends of sympathetic nerve in the iris.  When full amount (leaves) chewed one works cheerfully as long as the effect lasts, irrespective of meal hour, which may continue 3-4 days from repeated doses -- usually, however, food is taken at night, and only the meal of mid-day bridged over.  Natives drink its tea like Chinese tea elsewhere, and carry a bag of leaves and one of ashes or lime; after forming a quid of the leaves deprived of ribs (3j-4 Gm.), a little ash or lime is added to give pungency and to aid the secretion of saliva; each chew lasts an hour, when a new one follows.  Cocaine, in general action, resembles atropine; causes little injury to native, but strangers soon become haggard-looking and idiotic.
    USES. -- In melancholia, hysteria, epilepsy, spinal paralysis, insanity, diabetes, headache typhoid state, opium-habit, uterine inertia, vomiting of pregnancy, gastric irritability, cholera morbus, spermatorrhea, debiity, poisoning by chloral hydrate, opium, or bromides.  Locally, to burns, painful ulcers, fissures of anus, hay fever, sore throat, laryngitis, hemorrhoids, bronchitis, coryza, and in surgical operations; hypodermically in fingers, toes, small tumors--for amputation; for spinal anesthesia not as safe as novocaine, stovaine, eucaine; no more than gr. 3/4 (.045 Gm.) should be applied at once.
    Poisoning: Have nervous excitement, oppression, and fullness of head, sometimes nausea and vomiting, pulse and respiration at first rapid, then slow, breathing labored, face cyanotic, pupils dilated, extremities cold, convulsions, coma, death; may have delirium and unconsciousness early, or only asphyxia.  Place in horizontal position and fresh air, empty stomach, stimulants -- strong coffee, etc., and if circulation fails -- strychnine, ether, alcohol, amyl nitrite, caffeine, atropine, oxygen and ammonia inhalations; chloral hydrate (gr. 30-60 (2-4 Gm.), paraldehyde, sulphonal, chloroform, ether or morphine injections; artificial respiration; nitroglycerin (hypodermically) for convulsions.  Chronic poisoning (cocainism or habit), marked by loss of flesh, disordered circulation, insane delusions and hallucinations, collapse, is more rapid and nearly as degenerative and serious as that of opium, and may be treated similarly, but usage does not create nerve irritation to the same extent, consequently one with strong will power may desist abruptly its use without suffering other than the denial of mental satisfaction and pleasures, the craving for which it tends to establish.
    Incompatibles: Alkalies, alkaline carbonates and bicarbonates, mercuric chloride, iodine, iodides, ammonia, zonc chloride, borax.
    Synergists: Cerebral effects -- alcohol, cannabis, belladonna; analgesic--atropine, phenol, conium, opium; mydriatic--atropine.

    Commercial. -- The blue-gum tree of Tasmania (exuding blue-gum), discovered by Labillaradiere, French botanist, 1792, and introduced into Europe, 1856, is sensitive to cold, but under favorable conditions attains the height of 15 M. (50 degrees) in 6 years; there are 135 species, the wood of many being hard, resinous and valuable.  The aborigines knew something of its virtues, while the Spaniards used it for fever and ague, 1867, but Drs. Brunel and Ramel extolled and proved its antiperiodic properties, 1868-1869.  Leaves are picked, dried carefully, and enter trade very little broken, those that are ovate, equilateral, thin and sessile, "junior," being rejected; only the Australian variety should be used, as they vary less in the yield of oil; however, most of our supply comes from California.
    CONSTITUENTS. -- Volatile oil 6 p.c., tannin, cerylic alcohol, 3 resins (1 acid, crystallizable), eucalyptic acid.
    Oleum Eucalypti.  Oil of Eucalyptus, U.S.P. -- (Syn., Ol. Eucalypt., Eucalyptus Oil; Fr. Essence d'Eucalyptus; Ger.

Eucalyptolum, Eukalyptol, Zineol.)  This substance obtained from oil of eucalyptus and other sources (cajuput, canella, curcuma, laurus, mentha, rosemary, salvia, santonica) is the most valuable constituent of eucalyptus oil, being neutral and with a definite chemical composition, which is not true of the oil, and may be obtained by distilling the volatile oil and placing in a freezing mixture that portion coming over between 150-176 degrees C. (302-347 degrees F.), from which it crystallizes in long, colorless needles; a more satisfactory method is to treat the oil with hydrochloric acid gas or phosphoric acid, add warm water to separate eucalyptol on the surface, then wash with dilute alkali solution and distil.  It is a colorless liquid, characteristic, aromatic, distinctly camphoraceous odor, pungent, spicy taste; slightly soluble in water, miscible with alcohol, chloroform, ether, glacial acetic acid, fixed or volatile oils, sp gr. 0.922, boils at 176 degrees C. (349 degrees F.), congeals at 0 degrees C. (32 degrees F.).  Tests: 1. Optically inactive (dist. from oil of eucalyptus, many other volatile oils); alcoholic solution (1 in 10) -- neutral.  2. Place 1 cc. in freezing mixture, add gradually phosphoric acid (1) -- solid, white, crystalline mass (eucalyptol-phosphoric acid), + warm water -- eucalyptol separates.  3. Shake 5 cc. with sodium hydroxide T.S. (5) -- eucalyptol volume not diminished (abs. of phenols, etc.).  4. Shake 1 cc. with distilled water (20), after liquids separate, add to aqueous layer 1 drop ferric chloride T.S. -- no violet color (abs. of phenols).  Impurities: Oil of eucalyptus, volatile oils, saponifiable oils, phenols.  Dose, mv-15 (.3-1 cc.).

    PROPERTIES. -- Antiperiodic, antipyretic, expectorant, stimulant, astringent, antiseptic, disinfectant, diaphoretic; like quinine arrests white blood corpuscle movement; increases flow of saliva, gastric juice, heart action, appetite, digestion; large doses produce indigestion, diarrhea, vomiting, muscular weakness, low temperature, renal and cerebral congestion, paralyzed respiration, death; destroys low forms of life, reduces arterial tension and enlarged spleen.  It antagonizes malaria thus: 1, its dead leaves elevate the low moist soil; 2, being a rapid grower, its leaves roots, etc., absorb much malarial soil-water and noxious germs, thus causing the surrounding country to become dry, thereby purifying the atmosphere; 3, its enormous foliage protects large areas from direct sun-rays which favor the generation of animalculae; 4, its aseptic emanations purify the air.  Owing to these properties it is cultivated largely in malarial districts, to render them sanitative, and to reclaim infected localities, as portions of Australia, Jamaica, Roman Campagna, etc.  It is eliminated by skin, bronchia, kidneys, lungs, with more or less irritation, imparting odor to breath and urine.
    USES. -- Intermittent fever, genito-urinary and pulmonary catarrh, chronic bronchitis, mucous membrane affections, asthma (smoked with stramonium).  Used when quinine is contra-indicated, intermittents, typhoid, scarlatina, whooping-cough, cancer, hemorrhages; externally--as antiseptic in ulcers, gonorrhea, spongy gums, gleet, deodorizer in diseases with disagreeable odor, preventive of putrefaction; spray beneficial in diphtheria, gangrene of lungs, fetid bronchitis.  Tincture (1) added to cod-liver oil (100) removes fishy flavor; the leaves deter moths entering woolen cloth; bark used for tanning, dyeing.
    Incompatibles: Agents aiding waste, alkalies, mineral acids, salts.
    Synergists: Aromatic bitters, antispasmodics, copaiba, cubeb, oil of turpentine, etc.
