Catechu is an herb. The leaves, shoots, and wood are used to make medicine. The two types of catechu, black catechu and pale catechu, contain slightly different chemicals, but they are used for the same purposes and at the same dose. Catechu comes with great anti-oxidant, therapeutic, and anti-bacterial properties. Whether you’re suffering from itchy skin, acne, or skin wounds, you can use Khadira in a variety of forms to get rid of skin issues.
