You will be astonished at the wonderful coldness running through this remedy. Coldness: Hardly a group of symptoms will arise without this accompanying coldness. Coldness of discharges, coldness of the body. You would also wonder at the remarkable prostration attending the various groups of symptoms, complete relaxation and exhaustion, coldness. Profuse sweat, vomiting and diarrhea. Profuse watery discharges. These conditions occur without apparent provocation. In cholera or cholera morbus, it seems that the fluids run out of the body. Lies in bed, relaxed prostrated, cold to the finger-tips, with corresponding blueness, fairly purple; lips cold and blue, countenance pinched and shrunken; great sensation of cold ness as if the blood were ice-water; scalp cold; forehead covered with cold sweat; headache and exhaustion; coldness in spots over the body; extremities cold as death. Full of cramps; looks as if he would die. This state comes out during the menses, during colic with nausea, with mania and violent delirium, with headache, with violent inflammations. Is it any wonder that Hahnemann predicted that Veratrum, Camphor, and Cuprum would become remedies in the cure of cholera; he saw in their nature the ability to cure. He saw the similitude. In cases of this sort which are characterized by superabundance of cramps, Cuprum is the simillimum. For those with coldness and blueness and scanty sweat, vomiting, and purging, Camphor is the remedy. These are called "dry cholera;" they sink down and die without exhaustive discharges. In proportion as there are coldness, blueness and scanty discharges, Camphor is indicated. In proportion as copiousness, blueness, and coldness are present, Veratrum is indicated. Secale has something of cholera in it. Podo. has exhaustive stools. Ars. anxious restlessness.
