Burma (Myanmar), Thailand and Indo-China; cultivated in Malesian gardens as an ornamental.

In Thai traditional medicine, the roots are employed in the treatment of abscesses, gonorrhoea, as an alterative and anthelmintic. The leaves are used in the treatment of wounds, as an antipyretic, and against dysentery. The sapwood is used in the treatment of threadworm. The seeds or the whole plant are used in the treatment of roundworm, and gastro-intestinal ailments associated with intestinal parasitism in children. The whole plant is further employed against abscesses in paediatrics, and against stomach-ache. In Indo-China, the roasted seeds, bark or the leaves are used as an anthelmintic against Ascaris. It was formerly planted for raising a scale insect Laccifer lacca to produce lac, a raw material for the production of shellac.
