Nux Vomica.—See [Strychnine].
Oleandrin.—See [Digitalis].

Oxalic Acid—Binoxalate of Potash—Sodic Oxalate.
Unless the patient has already vomited freely, empty the stomach at once by emetics of zinc sulphate or mustard; or the stomach-pump or tube may, in most cases, be used. If the acid has been taken, neutralise by chalk, lime water, or, better, by saccharated lime water; but on no account neutralise by carbonate of soda or any alkali, for the alkaline oxalates are extremely poisonous.
Assist elimination by the kidneys by giving plenty of water; apply hot fomentations to the loins.
An enema may be given, if necessary, to empty the bowels well.
Phosphorus.
Empty the stomach by tube or pump, and, at the same time, wash the organ out with water to which has been added a drachm of French turpentine, or give emetics. The best emetic for phosphorus is said to be sulphate of copper, 4 or 5 grains dissolved in water, and given every ten minutes until vomiting is produced.
