Supari

The areca nut is not a true nut but rather a drupe. It is commercially available in dried, cured and fresh forms. While fresh, the husk is green and the nut inside is so soft that it can easily be cut with an average knife. In the ripe fruit the husk becomes yellow or orange and, as it dries, the fruit inside hardens to a wood-like consistency. Usually a few slices of the nut are wrapped in a Betel leaf along with lime and may include clove, cardamom, catechu (kattha), etc. for extra flavouring. Betel leaf has a fresh, peppery taste, but it can be bitter depending on the variety.

Areca nuts are chewed with betel leaf for their effects as a mild stimulant, causing a mild hot sensation in the body and slightly heightened alertness, although the effects vary from person to person. The effect of chewing betel nut is relatively mild and could be compared to drinking a cup of coffee. The areca nut contains tannin, gallic acid, a fixed oil gum, a little terpineol, lignin, various saline substances and three main alkaloids: Arecoline, Arecain and Guracine which have vasoconstricting properties. The betel leaf chewed along with it contains eugenol, also a vasoconstrictor. Many chewers also add small pieces of tobacco leaf to the mixture, thereby adding the effect of the nicotine, which causes greater addiction than the drugs contained in the nut and the betel.

In the Indian Subcontinent the chewing of betel and areca nut dates back to the pre-Vedic period Harappan empire. Formerly in India and Sri Lanka it was a custom of the royalty to chew Areca nut and betel leaf. Kings had special attendants carrying a box with the ingredients for a good chewing session. There was also a custom to chew Areca nut and betel leaf among lovers because of its breath-freshening and relaxant properties. Hence there was a sexual symbolism attached to the chewing of the nut and the leaf. The areca nut represented the male and the betel leaf the female principle. Considered an auspicious ingredient in Hinduism, the Areca nut is still used along with betel leaf in religious ceremonies and also while honoring individuals in most of Southern Asia.

Chewing the mixture of areca nut and betel leaf is a tradition, custom or ritual which dates back thousands of years from South Asia to the Pacific. It constitutes an important and popular cultural activity in many Asian and Oceanic countries, including Taiwan, Myanmar, Cambodia, the Solomon Islands, Thailand, Laos, and Vietnam. It is not known how and when the areca nut and the betel leaf were combined together into one psychoactive drug.
