Such as false mushrooms, belladonna, henbane, or anything a child may have eaten, or taken in mistake by any person. Vegetable poisons act either as an irritant, acro-narcotic, or narcotic. If it is an irritant, the symptoms are an acrid, pungent taste, with more or less bitterness, excessive heat, great dryness of the mouth and throat, with sense of tightness there, violent vomiting, purging, with great pain in the stomach and bowels, breathing often quick and difficult, appearance of intoxication, eye frequently dilated, insensibility resembling death. The symptoms of narcotic poisons are described under opium.
TREATMENT. -- If an irritant and vomiting does occur and continues, render it easier by large draughts of warm water, but if symptoms of insensibility have come on without vomiting, empty the stomach with any emetic that may be at hand,--sulphate of zinc, mustard; and after the operation of the emetic give a sharp purgative. After as much as is possible of the poison is got rid of, very strong coffee, or vinegar diluted with water, may be given with advantage. Camphor mixture with a little ether may be taken frequently, and if the insensibility is considerable, warmth, frictions, and blisters may be employed. For the narcotics proceed as in opium.
