Jambosa root. Jambosa vulgaris. Rose-apple.
Jambosa Root.—This is the root of Jambosa vulgaris DC., of the Fam. Myrtaceae, which is widely cultivated in the tropics under the name of the rose-apple. It has been found by A. W. Gerrard to contain an oleoresin, besides a crystalline principle, jambosin, C10H15NO3. Lyons has also found in it minute quantities of an alkaloid. The decoction of the bark of the root is used as an astringent in dysentery, gonorrhea, and leucorrhea. (P. J., March, 1884.)
