''[[Solanum hastifolium]]'' Hochst. ex Dunal occurs from Sudan south to Tanzania. In Kenya a root decoction was used to treat children with smallpox and a root infusion is drunk against abdominal pain, diarrhoea and as a laxative or emetic. The Maasai people administer a root decoction to cattle as a remedy for anthrax. Goats and sheep sometimes browse on it in the dry season.

''[[Solanum taitense]]'' Vatke occurs in Kenya, Uganda and Tanzania and ''[[Solanum zanzibarense]]'' Vatke is a coastal species occurring from Kenya to South Africa. Of both species, the roots are chewed and the sap is used as a mouthwash against toothache. The Maasai people boil the roots of ''Solanum taitense'' and the resulting liquid is sieved and drunk as a cure for arthritis, malaria, typhoid and stomach-ache.
