Poison: Toxic to livestock and also used as a fish poison.

Erosion control: In Africa, it is appreciated for its dense foliage hence annual cover crop.

Medicine: Leaf juice is used to treat dropsy and diabetes in India.

Soil improver: Used as green manure and annual cover crop in Africa, tested in Indonesia.
