Cubeb, Piper cubeba. Official in all standards, the oil in the British and U. S. The oil (average dose, 8 minims) is the preferable form for its use in genito-urinary affections. The action is that of copaiba (q. v.), but the secondary effects are even more annoying than are those of copaiba. While an active remedy, there are so much better resources in the treatment of gonorrhea that cubeb is falling into disuse.
Cubeb possesses some value in the treatment of chronic bronchial affections, being commonly used in the form of a lozenge or inhalations of the vaporized oil.
