Medicinal and toxic plants from Equatorial Africa: a pharmacologic approach.
The pharmacological approach to the study of plants used in traditional medicine is discussed. On the basis of personal experience in the Republics of Congo and Central Africa the author finds only a very small percentage of non-active plants among those used in traditional medicine. Some previously unknown plants are reported.
