Uses

Since ancient times C. fistula has been used as a laxative throughout the tropics. In Papua New Guinea, Central Province, broken bones and tropical ulcers are bandaged with bark scrapings and leaf sap. In Thailand, the heartwood is traditionally applied as an anthelmintic. The wood is occasionally used e.g. for posts, carts and agricultural implements. The bark is used for tanning and as an ingredient in betel paste.
