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, Indonesia, and Thailand. The leaf is known for its aromatic qualities and is typically chewed with areca nut and slaked lime, creating a popular stimulant known as paan. In addition to its cultural significance, betel leaf has been used in traditional medicine for its potential health benefits. It is believed to have antimicrobial properties and may aid in digestion. However, excessive consumption can lead to health risks, including an increased risk of certain cancers.
