Oroxylum indicum is a species of flowering plant belonging to the family Bignoniaceae.
The Oroxylum indicum seed is used in the traditional Indian ayurvedic medicine. The root bark is also used, administered as astringent, bitter tonic, stomachic and anodyne. It is included in famous tonic formulations, such as Chyawanprash. The bark of O. indicum (Singhala / Sri Lanka: Totila, Totilla) is one of main ingredients in Sri Lankan indigenous medicine (in decoctions) as a remedy for pains in joints or rheumatism.
The leaf contains chrysin and baicalein. Tetuin, the 6-glucoside of baicalein, is reported in the seeds. Other flavonoids, known for their anti-inflammatory and anti-allergy effects, are also present, though it may need to be used in high doses to get a response. Oroxindin has also been isolated from Oroxylum indicum whereas oroxylin A is reported in the root bark.
