Distribution
Tropical Africa, tropical Asia and the Pacific region. Common throughout South-East Asia but not reported for New Guinea and Borneo; reports for Peninsular Malaysia are contradictory. Widely cultivated in other tropical and subtropical regions.
Uses
In Indonesia, a poultice of the roots is used as a remedy for rheumatism, paralysis, tumours, toothache (as a counter-irritant) and swollen glands. The root-bark is used as a vesicant. To this end, the fresh root is cut into very thin slices, which are tied on the skin. Similarly these slices may also be applied to the forehead against headache. The leaves are also used in the treatment of rheumatism and headache. Locally, P. indica is used as an abortifacient, either internally by topical application for its vesicant properties, or by chewing the roots for some time. In veterinary medicine, it is given as a vermifuge to horses only. In Malaysia, leaves and roots are externally applied in the treatment of rheumatism, glandular swellings and leprosy. In the Philippines, the bark is used as vesicant and the roots are employed in poultices to treat headache. The bark is also said to be an antidyspeptic. In Thailand, the dried root is credited with emmenagogue, stomachic and carminative activities, and it is reported to be used in the treatment of haemorrhoids, as an abortifacient and as a means to purify the blood and stimulate digestion. P. indica is widely cultivated for its ornamental value.
