Cassia singueana, or African cassia, is a small tree that’s native to tropical Africa, particularly in countries like Ethiopia, Angola, Namibia, Zambia, Malawi, Zimbabwe and Mozambique. A plant with a variety of uses, the African cassia tree is often grown in these parts as an ornamental plant as well as a source of food and medicine. While the seeds and leaves of this tree are edible, its root bark, stem bark and leaves are widely used for medicinal purposes. In a recent study, researchers in Nigeria investigated the phytochemical composition of the root bark of the African cassia tree. They noted that parts of the tree are traditionally used for the treatment of pain and body aches associated with malaria, but the specific components responsible for its therapeutic effects have not been identified.
