Combretum molle has been used in traditional medicine since time immemorial for the treatment of a wide range of diseases. Indeed, almost every part of this plant (roots, leaves, seeds, twigs, and stem bark) has been used in African traditional medicine for the treatment of various ailments and diseases. An infusion or decoction of the roots, stem bark or leaves is taken to treat a large variety of health complications including abdominal pain, colic, constipation, intestinal worms, dysentery, fever, malaria, oedema, headache, backache, leprosy, HIV infections, cough, angina, tuberculosis, and other chest complaints. The plant is used for treating jaundice and yellow fever, diarrhoea, blennorrhoea, anuria, and sometimes administered to women in childbirth to hasten the expulsion of the afterbirth. It is also taken to induce abortion and to treat post-partum bleeding.
The bark is used medicinally in many parts of Africa. Combined with cereal foods, the bark is administered for the treatment of dysentery, and is used in ceremonial preparation for young children to prevent sickness and other troubles. An infusion of the inner bark is taken orally or as an enema to relieve various stomach ailments. The bark exudes a mumuye gum that can be used to treat wounds. An aqueous suspension of the powdered bark together with the mumuye gum obtained from its bark is used as a gargle and in draught for treating sore throat. The powdered bark is applied to body sores. In some communities, the stem bark of Combretum molle has a long-standing reputation for the treatment of liver diseases, malaria, and tuberculosis.
