Mustard is a stimulant, local emetic. It acts promptly and efficiently. In emergencies, other emetics not being available, it may be employed in narcotic and other forms of poisoning. As an emetic it is especially adapted to depressed conditions of the system— for, while it causes vomiting, it stimulates the action of the heart. When, therefore, an emetic is indicated, and at the same time the circulation is feeble, the surface cold, and the functions of animal life oppressed, mustard should be used.

Administration

A tea- to a dessert-spoonful of powdered mustard should be stirred up in a tumblerful of tepid water, and quickly swallowed. The irritant action of the mustard may be limited, and its emetic action promoted, by the free use of diluents.
