Uses.—In the Philippines this plant has the same applications as the Lagundi or Vitex, soon to be described. In India they give a decoction of the leaves for chronic rheumatism, the action probably being diaphoretic. The juice is employed for the coughs of childhood and externally as a resolvent for enlarged cervical glands. The bark of the young branches has a purplish color; in Java it is considered a good emetic.

Uses.—The Filipinos are but slightly familiar with this plant and it has no place in their therapeutical armamentarium. In India, however, it is very common and enjoys much reputation in the treatment of catarrhs, the grip, asthma and non-febrile, especially chronic, bronchial affections. The flowers, leaves and roots, but especially the flowers, possess antispasmodic properties and are prescribed in certain forms of asthma; they are bitter and slightly aromatic, and are given in infusion or electuary.
Drs. Jackson and Dott have testified from their own experience to the usefulness of the drug in chronic bronchitis, asthma and afebrile catarrh. Dr. Watt states that the natives of Bengal find relief for asthma in smoking the leaves. In Bombay its expectorant action is commonly known and its juice is used, mixed with borax and honey.
The dose of the aqueous extract made by evaporating the juice of the leaves, is .25–1 gram. The tincture is preferable, made by dissolving this extract in alcohol; dose 2–4 grams. Its efficiency is increased by the addition of pepper seeds (Waring). The Sanscrit writers recommend for cough, 3.80 grams of the leaf juice with honey. “It is very desirable that further trials be made to test the value of this remedy.”—Pharmacopœia of India.
