Khasi woman preparing her Betel nuts (India)
The woman is removing the husk of an Areca nut.
The Areca nut is then wrapped with Betel leaf and chewed for its exhilarating lift. Betel chewing has been claimed to produce a sense of well-being, euphoria, heightened alertness, sweating, salivation, a hot sensation in the body and increased capacity to work.
Just like alcohol, tobacco, coffee and sakau, Areca nut and Betel leaf are culturally-approved psychoactive drugs.
The Areca nut, by association, is sometimes inaccurately called the "Betel nut" or "Betel Quids".
