A decoction of the inner bark and fresh leaves is used as a treatment for diarrhoea. A brew of small sections of the bark is taken to treat stomach-ache. An infusion of the leaves is used as a laxative. The pods can be eaten and the pulp can be made into drink. Grounded up seedpods used as raw material for making biofuels.
