Areca nut palm, also known as betel nut palm or supari tree, is a tropical tree native to India and the South and Southeast Asian regions. It is widely cultivated for its edible nuts, harvested from the tree’s fruit. Areca nuts are commonly consumed in many parts of the world, either on their own or in a mixture of other ingredients such as tobacco, lime, and other herbs. The areca nut is known for its mild stimulant effects, which are caused by alkaloids such as arecoline in the nut. It is also used in the production of betel quid. It is also used in traditional medicine in some cultures for its astringent and digestive properties.
