The volatile oil of matico probably has much the same action as that of cubeb, influencing chiefly the genito-urinary passages. It has been given for the same cases, but is now rarely used. The leaves are sometimes placed upon a bleeding surface. Their numerous hairs promote the clotting of the blood, and thus they are haemostatic.
