Vettilai, paan in Hindi and tambula in Sanskrit, is the betel vine, a climbing pepper relative grown for its glossy, heart-shaped leaves. The leaves are chewed with areca nut and slaked lime as paan and offered at weddings, festivals and worship. Magahi paan from Bihar holds a geographical indication, and Banarasi paan is famous across India. The leaf itself is not the main hazard; areca nut and tobacco in paan cause mouth cancer.
