Arsenic demands oil or melted fat, with magnesia or lime water in large quantities, till vomiting occurs.
Corrosive Sublimate, (often used to kill vermin,) and any other form of mercury, requires milk or whites of eggs in large quantities. The whites of twelve eggs in two quarts of water, given in the largest possible draughts every three minutes till free vomiting occurs, is a good remedy. Flour and water will answer, though not so surely as the above. Warm water will help, if nothing else is in reach. The same remedy answers when any form of copper, or tin, or zinc poison is taken, and also for creosote.
Lead and its compounds require a dilution of Epsom or Glauber salts, or some strong, acid drink, as lemon or tomatoes.
Nitrate of Silver demands salt water drank till vomiting occurs.
Phosphorus (sometimes taken by children from matches) needs magnesia and copious drinks of gum Arabic, or gum water of any sort.
Alcohol, in dangerous quantities, demands vomiting with warm water.
When one is violently sick from excessive use of tobacco, vomiting is a relief, if it arise spontaneously. After that, or in case it does not occur, the juice of a lemon and perfect rest, in a horizontal position on the back, will relieve the nausea and faintness, generally soothing the foolish and over-wrought patient into a sleep.
Opium demands a quick emetic. The best is a heaping table-spoonful of powdered mustard, in a tumblerful of warm water; or powdered alum in half-ounce doses and strong coffee alternately in warm water. Give acid drinks after vomiting. If vomiting is not elicited thus, a stomach pump is demanded. Dash cold water on the head, apply friction, and use all means to keep the person awake and in motion.
Strychnia demands also quick emetics.
The stomach should be emptied always after taking any of these antidotes, by a warm water emetic.
