Action and Medical Uses.—This forms a stimulant and anodyne application in contusions, sprains, bedsores, rheumatic, neuralgic, and other pains. In glandular enlargements it is used as a resolvent, being particularly employed in the forming stage of mastitis, both as a resolvent and to assist in checking the secretion of milk. For the latter purpose, it should be applied as warm as can be borne.
