Betel nut tree

Ancient food from asia...

Areca nuts are chewed with betel leaf for their effects as a mild stimulant, causing a hot sensation in the body, heightened alertness and sweating, although the effects vary from person to person. 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.[1] 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. The effect of chewing betel nut is relatively mild and could be compared to drinking a strong cup of coffee.
