Betel leaf is a heart-shaped leaf from the Piper betle plant, commonly found in tropical regions of Asia. It is often used in traditional practices, particularly in countries like India, Bangladesh, and Indonesia. The leaf is typically chewed along with areca nut and slaked lime, creating a popular stimulant known as paan. In addition to its cultural significance, betel leaf is also recognized for its potential health benefits. It contains antioxidants and has antimicrobial properties. However, excessive consumption can lead to health issues, including an increased risk of certain cancers, making moderation important.
