In Peninsular Malaysia, a decoction of the root bark is applied internally to treat dysentery. In Sumatra, a decoction of the bark and leaves is used to treat stomach-ache. Also in Indonesia, fresh sap is applied as an antidote to centipede bites. In Brunei a leaf decoction is also used as an antidote to poisoning of a general nature. The wood is used for building houses, and for implements. The bark has been used for tanning and dyeing. The resinous gum is applied as glue, and the leaves for wrapping up food.
