A resinous substance, from the styrax, an East Indian tree. The compound tincture of Benzoin is a good medicine for bronchial cough. Dose, fifteen to twenty drops, on a lump of sugar, every three or four hours ; or at the beginning of a spell of coughing. The same tincture, applied with a camel's-hair pencil, is very healing to a sore nipple or a cracked lip, or even a fissure of the anus.
