All parts of this plant (Monkshood, Aconitum napellus) are poisonous-The only form in which any one is likely to take it injuriously is that of the Tincture of aconite root, in overdose (the proper dose is one, two, or three drops), or by mistake for something else. Death has been caused in this way : two bottles are standing by a patient's bedside, one containing a medicine to be taken internally, and the other a liniment for external application ; an attendant, by mistake, rubs a painful part with the medicine, and gives him a tablespoonful dose 01 the aconite liniment.
Symptoms: burning, tingling, and numbness of mouth, throat, and stomach, extending afterwards through the whole body; sickness of stomach, dizziness, prostration, sometimes convulsions; no delirium, no stupor, unless in quite exceptional cases. Death, from a sufficient quantity, results in a few hours. Less than a half a teaspoonful of the tincture has proved fatal in some instances; a teaspoonful will always be likely to do so, if left long in the stomach.
There is no chemical antidote for aconite. Vomiting should be produced at once to get rid of it. In the household, do not wait to send to a druggist, but give immediately a teaspoonful of mustard, mixed in a teacupful of warm (not hot) water. Repeat this in ten minutes, with large draughts of warm water, if vomiting does not follow. If no mustard is at hand, a tablespoonful of salt, in a teacupful of warm, not hot, water, will answer the same purpose. Then mix powdered charcoal, a teaspoonful at a time, in water, and let it be drunk; and also very strong tea, freely taken, Let the limbs be briskly rubbed with warm hands, and place hot bottles or bricks alongside of the body and to the feet. If other treatment is used, it should be only at the judgment of a physician, who should be summoned as soon as possible. This remark will apply to all cases of poisoning ; and need not therefore be hereafter repeated.
