Ipomoea Hederacea

This plant is not used as a medicine by the Filipinos

USES.—This plant is not used as a medicine by the Filipinos, but is official in the Pharmacopoeia 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.

Seeds 75 grams.

Alcohol 500 grams.

COMPOUND POWDER OF KALADANA.—Dose, 3–3½ grams.

Powdered seeds 150 grams.

Acid tartrate of potassium 270 grams.

Powdered ginger 30 grams.

The last is an excellent substitute for the corresponding preparation of jalap.

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.

BOTANICAL DESCRIPTION.—A twiner with round, downy stem. Leaves heartshaped, 3-lobed, the middle one broad-lanceolate, the lateral ones rather rectangular with petioles of equal length with the leaves. Flowers large, rose color or pale blue, in axillary cymes of 2 or 3 flowers each. Calyx, 5 long, downy parts. Corolla bell-shaped, 5 faint lobes. Stamens 5, free, inserted in the corolla. Ovary free, 3 biovulate locules. Style simple. Stigma trilobed. Seed vessels globose with 3 locules each containing 2 seeds. Seeds convex on dorsum, 1/2 cm. broad by 1 cm. long, testa black.

HABITAT.—Manila. Blooms in August.
