Betel leaves are the heart-shaped leaves of the betel vine, a climbing plant native to Southeast Asia. These leaves are commonly used in various cultural practices, particularly in countries like India, Bangladesh, and Thailand. They are often chewed with areca nut and slaked lime, creating a popular stimulant known as paan. In addition to their recreational use, betel leaves have traditional medicinal properties. They are believed to aid digestion, freshen breath, and possess antimicrobial qualities. The leaves are also used in religious and ceremonial rituals, symbolizing hospitality and respect in many cultures.
