                                Originating from the heartwood of the *Senegalia catechu* tree, black catechu has been a staple in traditional Asian medicine and chewing mixtures for centuries. Its numerous regional identities, including the very common names 'katha' and 'khair' in India, reflect its widespread use and cultural significance across the continent.
