Quassia is a simple tonic, and can be used with safety by any one, as
it does not increase the animal heat, or quicken the circulation.
_Used internally_, in the form of infusion, it has been found of great
benefit in indigestion and nervous irritability, and is useful after
bilious fevers and diarrhoea.
_Dose_, of the _infusion_, from one and a half to two ounces, three
times a day.
