Oroxylum indicum is a species of flowering plant belonging to the family Bignoniaceae. It is a tree which can reach a height of 12 m (40 ft). The large leaf stalks wither and fall off the tree and collect near the base of the trunk, appearing to look like a pile of broken limb bones. Oroxylum indicum is native to the Indian subcontinent, in the Himalayan foothills with a part extending to Bhutan and southern China, in Indo-China and the Malesia ecozone. It is visible in the forest biome of Manas National Park in Assam, India. It is found, raised and planted in large number in the forest areas of the Banswara district in the state of Rajasthan in India. 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.
