In Indo-China and the Philippines the bark of the trunk and root are used in the same way as in Myanmar. On the Malay Peninsula the bark is used for dysentery. A decoction of the leaves is drunk for stomach disorders, rheumatism, and wounds; and is made into hot fomentations to treat cholera, fever, and rheumatic swellings. The cooked leaves are used as poultices for various ailments during and after childbirth; also for dysentery, and to relieve headache and toothache. In Indonesia the bitter bark serves as a remedy for stomach problems, and also as a tonic and appetizer. Additionally, the bark is chewed as a depurative, especially after parturition. The flowers are used as a remedy for inflammation of the eyes. The pith serves as a styptic. In the Philippines the juice from the crushed bark is rubbed on the back to relieve the ache accompanying malaria ( Perry 1980).

Oroxylin, isolated from the bark and seeds, has been found to be a mixture of three flavones, baicalein, 6-methylbaicalein, and chrysin. Oroxylin-A consists of phtalic and benzoic acids, and phloroglucinol ( Perry 1980).
