 Haronga bark and leaves (Harunganae madagascariensis cortex et folium) are mainly used traditionally to treat stomach ailments like dyspepsia, and mild pancreatic insuffiency, and to stimulate the production of gastric juices and bile. "In African countries the reddish sap obtained from the bark is used as a styptic and is applied topically to treat various skin diseases, wounds, leprosy and itch... Studies have shown that bark and leaf extracts are choleretic and cholekinetic. Furthermore, the drug stimulates secretion of digestive juices from both the pancreas and the stomach." \\
