Medicinal

The plant is often used in traditional medicine in Africa, where it is valued especially for its febrifugal and analgesic properties[]. Research has demonstrated the presence of medically active compounds in the plant.
The N-glycoside 4-oxonicotinamide-1-(1’-β-D-ribofuranoside) has been isolated from the fruits, branches and leaves[]. This compound had previously only been known from human urine, and had never been isolated from other higher plants. It is an interesting compound, particularly in influencing enzymatic processes[].
The fruits contain monomethyl fumarate, which is used to treat psoriasis[].
The fruits contain D-mannitol, which is used as a nutrient, dietary supplement and a texturizing agent[]. Due to its low hygroscopicity, it is often used as a dusting powder to protect products against moisture pick-up. A major use of D-mannitol is in chewing gum and it is also widely used in intestinal permeability tests[].

A decoction of the leaves, twigs, bark and roots is applied internally or externally in lotions, washes and baths[].

The roots are used to treat bowel complaints[]. A root infusion is applied as a treatment for throat abscesses, toothache and leprosy[].

Drinking the leaf juice is said to help during labour and childbirth[].

The fruit pulp is said to be emetic[].

Other Uses

The fruits are commonly used to make blue-black markings on the hands, face and body, sometimes to imitate tattooing[]. Plant fibres are coloured by soaking them in swamp mud to which the fruits and leaves of this plant have been added[].
A dye and an ink-like extract known as 'katambiri' is made from finely crushed seeds[]. To make a stronger dye and ink, the extract is sometimes mixed with leaves of Gardenia, Indigofera, Nauclea or Vitex and sugar or honey[].
A black dye can be prepared from the flowers[].

The twigs are used as chewsticks[].

The stems are used to make shafts of a long-handled chisel that is used for harvesting fruit bunches of oil palm, and elsewhere to make spear handles[].
