What is an "areca nut"?

Areca nut, also known as betel nut, is the seed of the Areca catechu palm tree, native to Southeast Asia and the Pacific Islands. It is commonly chewed in many countries as a stimulant, often wrapped in a betel leaf along with slaked lime and sometimes tobacco. Areca nut has a slightly bitter taste and produces a mild stimulant effect when chewed, similar to caffeine. However, it is associated with various health risks, including addiction, oral health problems, and an increased risk of oral cancer. Despite its cultural and traditional use in some societies, the consumption of areca nut has declined in recent years due to increasing awareness of its harmful effects on health.
