Swietenia. Swietenia febrifuga Roxb. (Soymida febrifuga Juss.) Rohan Bark. (Fam. Meliaceae.)—The bark of this East Indian tree contains a bitter principle and is said to be much used as an antiperiodic in half drachm (2 Gm.) doses. The extract is used in dysentery like kino.

Swietenia Mahogoni Jacq., or mahogany tree, which grows in the West Indies and other parts of tropical America, has also a bitter, astringent bark, containing catechin. (Bull. Soc. Chim. Paris, xxiv, 118.) The oil of the seeds is said to be used as a purgative in the West Indies. The bark of S. senegalensis Desr. (Khaya senegalensis A. Juss.), Juribali bark, is used on the coast of Africa in the cure of intermittents, and Caventou extracted an alkaloid from it. (Am. J. M. S., N. S., xx, 168.)
