Nom. Vulg.--_Mangit_, _Alangitngit_, Tag., Vis. Uses.--The leaves dried in the shade are used in some Visayan towns, in infusion to take the place of tea. The root is used by the Hindoo physicians as an alterative. Dr. R. Ross has employed it for that purpose in a decoction of 60 grams to 500 cc. of water; 60 cc. a day of this preparation gave him good results in secondary and constitutional syphilis. The Mohammedans of India consider the root an antidote for vegetable poisons. Botanical Description.--Small tree, 5-6° high, trunk straight. Leaves alternate or bunched in 3's or 4's at the nodes, lanceolate or spatulate, 3-toothed at apex, sometimes serrate toward the apex, set with short, stiff hairs. Petioles very short. Flowers axillary, in racemose panicles of a few flowers each. Common peduncle long, pedicel short. Calyx free, bell-shaped, persistent, divided almost to base into 5 narrow, downy parts. Corolla bell-shaped, 5 oval lobules. Stamens 5. Ovary oval, within the flower. Style bifid. Stigmas simple, truncate.

Convolvulus Family. _Ipomoea 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 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 4 1/2 liters. Tincture of Kaladana.--Dose, 8-12 grams. Seeds 75 grams. Alcohol 500 grams. Compound Powder of Kaladana.--Dose, 3-3 1/2 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.
