Catechu, also known as resin, is a natural substance derived from the Acacia tree and other plants, primarily used in the production of tannins, dyes, and various pharmaceuticals. It is a dark brown, amorphous powder that contains polyphenolic compounds, which give it its characteristic color and astringent properties. Catechu has been traditionally used in Ayurvedic and Unani medicine for its anti-inflammatory, antiseptic, and wound-healing properties. In addition, it is employed in the food industry as a flavoring agent and in the leather industry for tanning purposes. The resin's complex chemical composition, which includes catechin and other flavonoids, contributes to its diverse applications and potential health benefits.
