Resin of Kaladana.—Dose, 30–50 centigrams. It is prepared like resin of jalap and is a safe and sure purgative. In mass it has a dark color, but is gray when powdered. The odor is rather unpleasant, the taste sweetish and then acrid, nauseous, persistent, exciting the saliva and irritating the fauces. It was introduced into practice by Dr. G. Vidie.

Uses.—The dry, powdered leaves are dusted over bruises and ulcers. The entire plant is very mucilaginous and the bruised fresh leaves are applied like poultices to cancers and ulcerating tumors. In India the boiled leaves are applied locally in colic and in rheumatism; the juice is given internally in dropsy as a diuretic, the pounded leaves at the same time serving as a poultice to the œdematous parts.
