An oleoresin derived from one or more South American species of Copaiba.

Properties : Copaiba is a pale yellow to brownish-yellow liquid, having a peculiar, aromatic odor, and a persistent, bitter and acrid taste. It is practically insoluble in water, partially soluble in alcohol, and freely soluble in fixed and volatile oils.

Action and Uses: Copaiba is a mild stimulant, laxative and diuretic. It is chiefly excreted by the kidneys, partly by the bronchial mucous membrane, both of which it stimulates. It is also excreted by the skin and some-times produces an eruption closely resembling that of measles. It is slightly antiseptic.

Copaiba is sometimes used in chronic bronchitis as a stimulating expectorant. It is chiefly used in gonorrheal urethritis, being applicable only in the chronic form of the disease. It may be given in conjunction with oil of sandal or the oleoresin of cubeb.

Dosage: 1 c.c. or 15 minims in capsule or emulsion, four or five times a day.
