The dark reddish brown wood of Bischofia javanica is heavy and very hard, with a fine structure, and is used for bridges, vehicles, and structural timbers. The bark is a source of a red dye, used to stain rattan baskets. The fruits are mostly used for making wines. The seeds yield 30%-54% oil. The roots are used as a medicine for rheumatalgia and malaria.
