Bebeeru bark is an aromatic bitter, stomachic and tonic in its effects, like orange and cascarilla; the alkaloid possesses the properties of a pure bitter.
Like all other substances of this class, beberia is antiseptic, and to a small extent antipyretic and antiperiodic; but these effects being comparatively insignificant, its use in fever and ague has now been abandoned.
