Symptoms: Acrid, metallic taste in the mouth, immediate constriction and burning in the throat, with anxiety and tearing pains in both stomach and bowels, sickness, and vomiting of various-colored fluids, and sometimes bloody and profuse diarrhea, with difficulty and pain in urinating; pulse quick, small, and hard; faint sensations, great debility, difficult breathing, cramps, cold sweats, syncope, and convulsions. Treatment: If vomiting does not already exist, emetics must be given immediately—white of eggs in continuous large doses, and infusion of catechu afterwards, sweet milk, mixtures of flour and water in successive cupfuls, and to check excessive salivation put a half ounce of chlorate of potash in a tumbler of water, and use freely as a gargle, and swallow a tablespoonful every hour or two.
Symptoms: Intense pain and vomiting, and purging of blood, mucus, and shreds of mucous membranes; and if these stand they become dark. Treatment: Give freely of a solution of common salt in water, which decomposes the poison, and afterwards flaxseed or slippery-elm-bark tea, and after a while a dose of castor oil.
