Convolvulaceæ.
Convolvulus Family.
Ipomœa hederacea, Jacq. (I. nil, Roth.; Convolvulus nil, L. and Blanco.)
Nom. Vulg.—Bulakan, Tag.; Kala-Danah, Indo-Eng.
Uses.—This plant is not used as a medicine by the Filipinos, but is official in the Pharmacopœia of India from which we copy its indications and official preparations.
The seed is the part employed, its cathartic properties being much like those of jalap, though less energetic. An excellent substitute for the latter is 2 or 3 grams of kala-danah seeds in powder form, and no unpleasant effects attend its operation.
The official preparations are:
Extract of Kaladana.—Dose, 30–60 centigrams in pill.
| Powdered seeds | 500 grams. |
| Alcohol | 2 liters. |
| Water | 4½ liters. |
Tincture of Kaladana.—Dose, 8–12 grams.
