A tree of the wooded savannas of southern and central Africa, Diplorhynchus has long been known to traditional healers for its milky latex and bitter bark. Its wood, often used in carving, should not overshadow the more discreet use the elders made of it in the local pharmacopeia. Little studied outside its native range, it remains a plant of oral tradition, passed down from generation to generation.
The bark and sap were traditionally used against intestinal worms and various digestive disorders, in several southern African pharmacopeias.
The latex, applied locally, was traditionally used to promote the closing of minor wounds or to treat certain skin conditions.
A root or bark decoction was sometimes drunk to ease diffuse pain, according to uses reported by traditional healers.
In some regions, a bark-based preparation was traditionally used for stubborn coughing or mild respiratory conditions.
Diplorhynchus latex contains compounds related to those of other Apocynaceae, a family known for its potentially toxic alkaloids: any internal use must be supervised by a qualified professional. Internal use is strongly discouraged for pregnant or breastfeeding women, as well as young children, for lack of sufficient safety data. Do not exceed occasional, external, traditional uses without the advice of a practitioner familiar with the plant and its native region. In case of contact with the latex, avoid any prolonged contact with mucous membranes and the eyes.
