USES.—The small fruit known commonly as manzanitas has an agreeable taste, although ordinarily offered for sale before they are quite ripe. They are among the most popular dainties at the fairs and festivals in the provinces of Manila and are the only part of the plant used in medicine. They possess emollient qualities and are official in the codex. They enter in the composition of the so-called pectoral remedies (composed of equal parts of figs, dates, Corinthian raisins and manzanitas).

Rhamnus Wightii, W. & Arn. (Ceanothus Wightiana, Wall.; R. Carolianus, Blanco.) NOM. VULG.—Kabatiti, Tag.
USES.—The dried trunk bark is the part employed in medicine. Hooper analyzed it in 1888 and found a crystalline principle (0.47%), a brown resin (0.85), a red resin (1.15), a bitter principle (1.23), sugar, starch, calcium, oxalate, etc.
As the active principles exist in the resins, an alcoholic tincture of the latter is the best preparation for administration. In India it is used as a tonic and an astringent.
