Acacia catechu: Health Benefits, Bioactive Compounds, and Traditional Uses Explained
Acacia catechu—also known as Khair or black catechu—is a medicinal plant widely used in traditional systems like Ayurveda and Traditional Chinese Medicine. Derived mainly from the heartwood and bark of the tree, it has been valued for its antimicrobial, anti-inflammatory, and antioxidant effects.
What Is Acacia catechu?
Acacia catechu is a deciduous tree native to parts of South and Southeast Asia. Traditionally, various parts of the tree have been used to treat wounds, digestive issues, oral infections, skin conditions, and inflammation.
