Action, Medical Uses, and Dosage.—This is a cathartic and tonic, but is seldom used on account of its disagreeable taste, aloes being preferred in the pill form. As a cathartic, the dose is from ½ to 1 ½ fluid ounces. As a local application, on lint, it has been found useful in old sores, ulcers, wounds, etc.
