Jacobs analyzed the bark and isolated an amorphous resin of yellowish color and very bitter taste. It is soluble in alcohol, ether and chloroform, slightly soluble in sulphuret of carbon, insoluble in turpentine or benzin. He believes that it is the active principle of the root, and produces the anthelmintic action already mentioned: the proper dose is 0.20 centigrams to a child of 4 years, followed by a purge of calomel. Botanical Description.--A tree, 30-40° high, with leaves alternate, compound, odd-pinnate; leaflets opposite, ovate, pointed, dentate. Flowers in large axillary compound panicles. Calyx, 5 sepals. Corolla, 5 petals, rose-colored within, lilac-colored without. Stamens 10, united into a cylindrical tube, expanded at both ends, the mouth 15-toothed. Anthers inserted near the apex of the tube, short, fleshy, bilocular. Ovary free, of 5 biovuled cells. Style of equal length with the tube. Stigma button-shaped. Fruit a drupe, about the size of a small olive, yellow when ripe, with a dark brown pit of 5 one-seeded cells. Habitat.--Native of China; is cultivated in most gardens in the Philippines. _Dysoxylum Blancoi_, Vidal. (_D. salutare_, F. Villar; _Turroca virens_, Blanco.) Nom. Vulg.--_Igiw_, _Agiw_, _Taliatan_, Tag.; _Ananangtang_, _Bakugan_, _Makasili_, Vis.; _Malabangaw_, Pam.; _Basiloag_, Iloc. Uses.--The bark of the trunk, dry and finely powdered, is used in doses of 1 1/2-2 1/2 grams as an emetic, and, according to Padre Blanco, its effect is very certain. It is also a febrifuge, and Padre Mercado states that it cures "all forms of asthma, suffocative affections of the chest, and griping pains of the belly." He also states that it yields marvelous results in malarial fevers, given during the cold stage in doses of 4-8 grams in water or wine in which it has macerated 12 hours. He also recommends its use before breakfast as an anthelmintic in lumbricoids, and finally attributes to it virtues as an emmenagogue. Padre Blanco calls attention to the species _D. schizochitoides_, Turcz. (_Turroea octandra_, Blanco), _Himamaw_, Tag., as a substitute for _D. Blancoi_. The Tagalo "herb-doctors" pretend that the part of the bark near the earth is doubly efficacious, for which reason they administer only that portion which is within one meter of the ground, giving it in the doses already mentioned. Botanical Description.--Tree 16-20 meters high. Leaves glabrous, odd-pinnate, petioles very long; leaflets entire, opposite, short-petiolate, acute, oblique at the base. Flowers in axillary panicles. Calyx, 5 imbricated sepals. Corolla, 5 linear, lanceolate petals united at the base. Staminal tube, 10-toothed and 10-anthered. Ovary 5-celled, each cell containing two ovules. Style somewhat longer than the stamens. Stigma thick and depressed. Seed vessel globose, depressed, somewhat downy, 5-angled; with 5 compartments each containing 2 seeds. Habitat.--Batangas and Laguna. _Sandoricum Indicum_, Cav.
