Uses

The wood is easy to work but liable to crack unless very carefully seasoned. The fruits and seeds are eaten by the natives. The bark is used by the ab­origines for stupefying fish. The pulped leaves are considered a sure and safe cure for ulcers. Pulverized leaves are supplied as fermentations. The plant is suspected of causing death in cattle characterised by posterior paralysis and death in several days. Leaves of P. careya have been traditionally used in the treatment of wounds by the indigenous people of northern Australia, although the compounds responsible for the medicinal properties have not been identified. The isolation of six antibacterial compounds from the leaves of P. careya validates the use of this species as a topical wound-healing remedy ().
