Medicinal Actions & Uses

Black catechu is a strong astringent and clotting agent. It helps reduce excess mucus in the nose, the large intestine, or vagina. It is also used to treat eczema, hemorrhages, diarrhea, and dysentery. It may be used as an infusion, tincture, powder, or ointment. A small piece of cutch dissolved in the mouth is an excellent remedy for bleeding gums and canker sores. The powder and tincture are also applied to infected gums and have been used to clean the teeth. In Ayurvedic medicine, decoctions of the bark and heartwood are used for sore throats.
