The areca nut, or betel nut, is the fruit of the arcca palm tree, which is indigenous to Malaysia but is also grown in Sri
Lanka, India, Thailand and the Philli-pines. The betel nut has a red or orange outer skin and the actual nut is a light brown colour with white flesh. The people of South Asia chew this nut which is considered to aid the digestion and is a mild narcotic. The nut is often chopped into small pieces, wrapped in a betel leaf with lime and aromatic flavouring and chewed. Chewing the betel nut produces a flow of red saliva which temporarily stains the mouth and teeth.
