The wood is little used for fuel. The raw or cooked seeds are sold in the market and eaten in the Mossi area of Burkina Faso. The dry pods are readily eaten by cattle. The Peuhl of Burkina Faso prescribe a decoction of the leafy branches against flatulence. The Mossi consider the macerated roots taken in water with honey as an aphrodisiac. The flowers are a valuable source of pollen and nectar for bees.
