BEBEE′RINE (from bebeery, the native name of the tree). A bitter alkaloid occasionally used in medicine, in the form of its sulphate, as a substitute for quinine, and, on account of its stimulating action on the stomach, as a stomachic. It is obtained from the bark of the Greenheart-tree (Nectandra rodiœi of the order Laurineæ), indigenous to British Guiana.
