betel nut
Quick Summary
The betel nut is the astringent seed of the betel palm (Areca catechu), first used in 1673. It is a key component of betel quid, a mixture popular in South and Southeast Asia, chewed by about one-tenth of the world's population.12
A betel quid is made by wrapping a piece of betel nut in a betel pepper leaf with slaked lime to stimulate salivation and release alkaloids. Other ingredients like cardamom or turmeric may be added for flavor. The chewing process produces red saliva and can stain teeth and gums.2
Betel chewing is addictive and provides a mild stimulant effect. However, it is linked to serious health issues, including oral and esophageal cancers, and is considered a public nuisance due to staining and spitting. The betel palm is cultivated for its fruit, which contains the hard seed or nut. The unripe fruits are processed for chewing, and the nut's alkaloid, arecoline, is used by veterinarians.2
