Bark of the root of Simaruba amara.—South America.
Dose.—From five grains to half a drachm.
Therapeutic Action.—The Simaruba is said to be tonic, emetic, stomachic, cathartic, diaphoretic, and diuretic. It is tonic and stomachic when given in small doses, but in large doses it causes vomiting and purging, and is said to promote diaphoresis and diuresis. It is not used, however, to fulfill any indication except those of a tonic and stomachic.
