Medicinal

A decoction of the root bark is used to treat indigestion, diarrhoea, fever, snakebites, infertility and venereal diseases[].

A decoction of the root is used to treat a variety of complaints including chronic cough, pneumonia and pulmonary tuberculosis; rectal prolapse; diabetes; testicle inflammation; and to facilitate giving birth[]. Combined with salt, it is used to treat cough[].
Te root powder is taken with food to treat anorexia and is added to porridge in order to treat pain in the digestive tract[].
It is applied externally to treat sore eyes[]. The body is washed with an infusion of the root to treat measles[].

A leaf infusion is used to treat headache and stomach problems[].

The latex is smeared on cuts to heal them[]. It is believed to stimulate milk flow in nursing mothers, a few drops of the latex being sprinkled over the breasts[].

Alkaloids are present in both the stem bark and root bark, the latter being a richer source[]. These alkaloids belong to 3 main groups: yohimbine and its isomer β-yohimbine; nor-macusine B (tombozine or diplorrhyne), stemmadenine and condylocarpine; and 14-hydroxy-akuammicine (mossambine or diplorhyncine) and nor-fluorocurarine. Most of these compounds also occur in other members of Apocynaceae[].
An aqueous extract of the roots and stems is reported to be a useful sympatholytic. Ethanolic extracts of the roots did not show a significant antiplasmodial activity in vitro[].

Other Uses

A fibre obtained from the bark is used for weaving in a similar way as the bark fibre of baobab (Adansonia digitata)[].

A latex obtained from injuries to the plant is used to repair bicycle tyres[]. It is also used as glue to stick feathers and metal tips to arrows[]. The latex is also smeared on hides of drums to improve the tone[].

The wood is suitable for ornaments, furniture, fencing and firewood and to make charcoal[].
