About Betel Leaf
Betel leaf has been chewed after meals in India for over 2,000 years, and it holds a central place in weddings and rituals. Varieties such as Banarasi, Magahi (with a GI tag from Bihar), Calcutta and Mysore differ in pungency and texture. On its own, the leaf is a mild digestive and antiseptic. The serious health risk comes from what is wrapped in it — areca nut and tobacco.
Botanically known as Piper betle, it belongs to the Piperaceae family. It is native to South & Southeast Asia and grows best in a tropical/humid climate. The parts most often used are the leaves.
