Felter's Materia Medica on Veratrina

VERATRINA
   Veratrine, Veratria. A mixture of alkaloids obtained from the seeds of Schoenocaulon officinale, Asa Gray (Sabadilla officinarum, Brandt; Asagrea officinalis (Chamisso and Schlechtendal) Lindley; (Sabadilla seeds) (Nat. Ord. Liliaceae). Tropical regions from Mexico to Venezuela. Description.—A white or grayish-white, non-crystalline powder, without odor, but causing violent irritation and sneezing when even a minute quantity comes in contact with the nasal mucosa. It should not be tasted. Veratrine is slightly hygroscopic, though very sparingly dissolved by water (1,760 parts). It is very soluble in chloroform, alcohol and ether. Action.—Locally, veratrine (or its salts) is a violent irritant closely resembling aconitine in action. Applied in alcoholic solution, ointment, or oleate, it excites a singular sense of heat and tingling, or prickling pain, which, however, does not last long, but is followed by coolness and more or less numbness; there is seldom redness or vesication unless the preparation is strong and applied with brisk friction. Inhaled, even in minute quantity, it occasions severe coryza and excessive sneezing. Muscular twitching has resulted from its application in ointment to the face, and sometimes it gives rise to headache, nausea, griping, slight diarrhea, and depression of the action of the heart. When swallowed it is a violent, irritant poison, causing great acrimony in the parts over which it passes, salivation, peculiar prickling numbness of tongue and mucous membranes, violent vomiting, profuse and sometimes bloody, and bilious diarrhea (sometimes constipation); weak, irregular and quick pulse; cardiac depression; pallor of face and great faintness; cold sweats; muscular twitching and aching pain along the spine; contracted abdomen and pupils; and occasionally extreme pruritus and tingling which may persist for weeks. In so-called medicinal doses it produces a feeling of warmth in the stomach and bowels, which extends to the chest and extremities. In poisoning by it, the stomach should be thoroughly evacuated, and tannin solutions freely given and pumped out. Stimulation should be resorted to to overcome the depression; for this purpose alcoholics, aromatic spirit of ammonia, ammonium carbonate, artificial respiration, etc., may be employed. Therapy.—External. Veratrine should be used only as an external application, and then rarely, in superficial functional neuralgia, myalgia, herpes zoster, chronic arthritis, acute gout, and other painful local inflammations. It is less effective than aconitine, but both are equally dangerous and great care should be exercised that it is not applied where the epiderm is denuded, nor should it be allowed to come into contact with or even be used near the eye, on account of the violent conjunctivitis caused by it. A 2 per cent solution in equal quantities of olive oil and oleic acid is usually employed. Internal. Veratrine should not be used as an internal medicine.1

VERATRUM VIRIDE
   The dried rhizome and roots of Veratrum viride, Aiton (Nat. Ord. Liliaceae). An indigenous plant of swamps, low grounds, and moist meadows. Dose, 1 grain. Common Names: American Hellebore, Swamp Hellebore, Green Hellebore, Indian Poke. Principal Constituents.—A powerfully toxic alkaloid veratrine (C32H49NO9), or cevadine, ocurring in both crystalline and amorphous forms; protoveratrine (C32H51NO11), also extremely poisonous; jervine, vertroidine, pseudojervine, rubijervine (sternutatory) and resin. Preparation.—Specific Medicine Veratrum. Dose, 1/20 to 5 drops. Specific Indications.—Pulse full, frequent, and bounding; pulse full, rapid, corded or wiry; pulse full, strong, and intense, with throbbing of the carotids; pulse rapid and beating so forcibly that sleep is prevented; tissues full, not shrunken, and surface flushed with blood; increased arterial tension, with bloodshot eyes; erysipelas resembling an ordinary inflammation; cerebral hyperaemia; sthenic fevers and inflammations; irritation of nerve centers due to an excited circulation; convulsions, with great vascular excitement, full pulse, and cerebral hyperaemia; puerperal eclampsia; red stripe down center of the tongue; weight in the epigastrium, with forcible circulatory pulsations. Action and Toxicology.—Veratrum is a powerful circulatory depressant. The exact action of the individual alkaloidal constituents is yet undetermined, as well as the effect each produces in the sum total of the effects of the root. According to Wood, the drug is a spinal and arterial depressant having no direct action upon the spinal centers; the direct action of jervine upon the heart-muscle, and the stimulation of the inhibitory nerves by veratroidine lower the pulserate; the force of the heart-beat is lowered by the direct action of jervine upon the heart-muscle, while the same constituent, according to dose, produces a more or less complete vaso-motor paralysis. The depression of the spinal motor centers is attributed to jervine. The emetic action of veratrum is said to be due to the combined action of veratroidine and the resin. All vaso-motor depressants and all agents which diminish the vital force, favor the action of veratrum. Nausea is always the signal for suspension of the administration of the drug. Death from veratrum is caused by asphyxia. Veratrine and cevadine are identical. The veratrine of commerce, however, is variable in composition, but its action is probably mostly due to the amount of true cevadine present. Late investigations show that most of the action of veratrine is that of cevadine, though veratrum does not furnish the veratrine of commerce (see Veratrina). One of the peculiar effects of veratrine is that of muscular contracture produced when in contact with the heart and the voluntary muscles. It is exhibited in a prolongation of relaxation following the contraction of the muscle, appearing almost like a tetanic effect, but it is free from any rigidity or spasmodic quality—in reality a prolonged contraction in which there is a long and gradual relaxation several times longer in duration than that occurring in the unpoisoned muscle. American hellebore exerts an influence upon the system quite similar to that of White Hellebore (Veratrum album). Veratrine does not represent the action of this plant, which contains but a small proportion of this body. Applied to the skin, veratrum is rubefacient; and to the nose, excites sneezing. Small doses of veratrum appear at first not to affect the frequency of the pulse, but to lower its force; it afterwards slows the pulse, it becoming moderately full and soft, and remaining so, unless the patient, during this stage of depression, attempts to rise or make any exertion, when the pulse becomes very rapid, small, thready, and sometimes almost imperceptible. During the stage of depression there is marked muscular weakness and relaxation, and nausea and vomiting take place, the contents of the stomach being evacuated first, and then those of the gall-bladder. Occasionally a watery diarrhea is caused by veratrum, sometimes amounting to hypercatharsis, but as a rule purging is not produced. The nausea produced by veratrum is intense, and the vomiting severe and often persistent, making it, therefore, an unsafe emetic. The most characteristic action of veratrum is its effects upon the movements of the heart and upon vascular tonus. The pulse-rate has been lowered to thirty-five beats -a minute with this agent, a corresponding depression of force accompanying this action. When such depression is reached, it is seldom that emesis can. be prevented. In large doses it is a very dangerous agent, yet, singularly, fatalities from its use are rare. Toxic doses produce an exceedingly weak heart-action, almost indistinguishable, running pulse, reduced temperature, cold, clammy sweat, extreme retching and incessant vomiting, dizziness, faintness, failure of sight, pupillary dilatation, complete muscular prostration, slow, shallow breathing, sleepiness, coma, and unconsciousness, with sometimes stertorous breathing. The prompt emesis induced by this agent undoubtedly prevents lethal effects. In poisoning by veratrum, withdrawal of the drug and free stimulation will quickly overcome the depression. Large draughts of warm water may be given to encourage and assist emesis until the stomach has been thoroughly washed out. This should be followed by undiluted whiskey or brandy to check the vomiting. Opium or morphine may be given by mouth or otherwise, ammonia and alcoholics may be used by enema or hypodermatically, and strychnine or digitalis may be given by the latter method. External heat, sinapisms, friction, etc., must be utilized, and under no circumstances must the patient be allowed to rise from the recumbent position, not even to raise the head to vomit. Therapy.—External. Painted upon boils, felons, carbuncles, abscesses, inflamed acne, cellulitis, and other local inflammations, veratrum wi1
