Baup obtained several principles from it: (1) A resin, _brein_, fusible at 187°, soluble in cold alcohol, crystallizable in oblique rhombic prisms; (2) another crystalline substance, _bryoidin_, soluble in 360 parts water at 10°, and melting at 13°; (3) a small amount of _breidin_, a body soluble in 260 parts water and melting at 100°+; (4) another resin soluble in boiling alcohol, called _amyrin_. White pitch is used in the Philippines to make plasters which they apply to the back and breast of patients suffering from bronchial or pulmonary complaints; it is also applied to indolent ulcers. We believe that elemi possesses the same properties as copaiba, and that its indications for internal use are the same. Botanical Description.--A tree 30-40 meters high, with leaves alternate, odd-pinnate; leaflets opposite, coriaceous. Flowers yellowish-white in axillary, compound panicles, hermaphrodite. Calyx 3-toothed. Corolla, 3 oblong, concave petals. Stamens 6, inserted on the base of the disc. Ovary free, of 3 lobules each containing 2 ovules. Style simple. Stigma, 3 lobules. Drupe oblong, size of large prune, fleshy, containing a hard, 3-sided pit. Habitat.--Very common in all Philippine woods especially in Camarines. MELIACEÆ. Melia Family. _Melia Azedarach_, L. Nom. Vulg.--_Paraiso_ (_Paradise_), Sp.-Fil.; _Pride of India_, _China Tree_, Eng. Uses.--The root was official in the U. S. P., 1880, as an anthelmintic; it is administered in the following form: Fresh root bark 120 grams. Water 1 liter. Boil till reduced one half. Dose.--For a child 1 soup-spoonful every 15 minutes till nausea is produced. In view of the narcotic effects produced by this drug, the foregoing method of administration seems to us imprudent; we prefer to give 30-70 grams of the decoction and follow with a purgative such as castor oil. This drug is also tonic, febrifuge and astringent, and a decoction of its leaves and flowers is used as a wash for ulcers. Some believe that the leaves and fruit contain toxic principles, which may well be true considering the effects of large doses of their preparations. It has also been observed that the bark collected in March and April may cause dilatation of the pupil, stupor, etc.; this may be explained by the fact that at this season the sap is rising in the tree and the bark contains an increased amount of active ingredients. The fruit yields a fixed oil, and by fermentation and distillation produces alcohol. The root bark referred to is bitter and nauseous, if taken from the superficial roots--the part usually employed; the bark of the deeper parts is astringent by virtue of the contained tannin.
