Although th ere is no ethnobotanical usage recorded for this species, investigation on non-volatile isolates of this species was undertaken to help in the chemotaxonomy of the genus Heteropyxis. Heteropyxis natalensis is used by traditional healers to treat worms in stock, mental disorders and bleeding nose. It is also used during weaning and as a herbal tea. The chemical investigation of the leaves, stems and roots of Heteropyxis canescens afforded fourteen known compounds whereas that of the twigs and the roots of H. natalensis afforded ten known compounds. The current phytochemical investigation of the Psiloxyloideae has not revealed a significant variance from the chemical profile of the Myrtoideae.
