The first regular proving of *Crot. was made by Hering and under his direction. Stokes also contributed a proving, but the most complete account of the remedy is to be found in the monograph of *J.W. Hayward, forming part of *Materia Medica Physiological and Applied. This includes provings made by Hayward and his provers. *Crot. Produces profound nervous shock and prostration with trembling, mental alienation, and disorganisation of the fluids and tissues. It causes bleeding from all orifices and surfaces, and it corresponds to the haemorrhagic diathesis, to diseases caused by previous low states of system, by zymotic or septic poisoning, by abuse of alcohol, etc. Low, typhoid states, with oppressed nervous system, and degraded blood-supply often require it. Neuralgia occurring as a sequel of septic toxemic, or even miasmatic disease, or chronic bilious, climacteric, or albuminuric conditions. Broken- down constitutions. The *Crotal. patient is readily moved to tears. Weeping mood, agony, despair. In one prover perception was so clouded that she was in danger of being run over in the street, and memory was so impaired that on entering a shop she forgot what she had come for. Sleepy, but cannot sleep. Grinds teeth. “*Crotal. is preferable in fluid haemorrhages, yellow skin (hence in yellow fever with black vomit), epistaxis of diphtheria. *Naja has more nervous phenomena. *Lachesis has skin cold, clammy rather than cold and dry, haemorrhage, with charred-straw sediment, and more markedly ailments of the left side. *Elaps. is preferable in otorrhea and in affections of the right lung. The cobra poison (*Naja) coagulates blood into long strings. *Crot. poison is acid, the *Viper neutral. The Rotten-snake (“Birri”) causes more sloughing than any other ” (Hering). But Hayward observed that sloughing is a strong indication for *Crotal., and the cure by this remedy of his own daughter of scarlatina maligna, with gangrenous-looking sore- throat, was a dramatic outcome of his researches. A case of rattle-snake bite and its isopathic cure, related by Dr. ***J.S.M. Chaffee, in *Hom. *News, Sept., 1892, gives a good general idea of the action of the venom: “I was called to see James Wright, aged 54 years, who, while binding wheat, was bitten on third finger of right hand by a rattlesnake. I found him bleeding from the bitten finger, and from eyes, nose, ears, mouth, rectum and urethra, pulse 110, small, wiry, respiration 40, temperature 105, haggard expression, whole body bathed in hot perspiration, delirium. This patient had had the regular routine treatment of whisky, quinine and carbonate ammonia for ninety-six hours, when the attendants withdrew and pronounced the case beyond the reach of medical aid. A marked characteristic symptom was a *mouldy smell of breath, with scarlet red tongue, and difficult swallowing. Great sensitiveness of skin of *right half of body, so much so that the slightest touch would produce twitching of muscles of that side. I prescribed *Crot. hor. 30th trituration, 30 gr. in four ounces of water, a teaspoonful every hour, until my return visit, twenty-four hours later, when I found marked improvement. Temperature normal, pulse full, soft and regular, delirium gone, saliva and urine slightly tinged with blood, appetite returning, he having asked for food for the first time since the accident.” The medicine was continued for two more days, when recovery was practically complete. The action on the right side is noteworthy, as *Crotal. is predominantly a right- side medicine (*Lachesis is more left), it acts strongly on the liver and corresponds to jaundice and yellow fever. *Crot. has been used with great success in the treatment of yellow fever, and also as a prophylactic against it. For this, inoculation with diluted virus has been practised.

The *pains of *Crot. alternate rapidly with each other, and frequently recur, also (except headache) appear and disappear suddenly after lasting some time. Swelling of whole body. Fetor of evacuations and discharges. Haemorrhages from all the orifices and even pores of the skin. Peculiar sensations are: as from a blow on occiput, as if tongue and all round throat were tied up, as of a plug in throat to be swallowed, of choking, as if the heart turned over like a tumbler pigeon. Periodicity marks many of the symptoms. Metastasis of erysipelas to brain. Many symptoms are worse in morning on waking, or wake the patient up in the night. Orbital pains worse in evening. Rest better, and motion and exertion worse. Open air better head and stomach symptoms.Cold air worse throat and respiratory symptoms. Dry air worse cough.
