It is commercially available in dried, cured, and fresh forms. When the husk of the fresh fruit is green, the nut inside is soft enough to be cut with a typical knife. In the ripe fruit, the husk becomes yellow or orange, and as it dries, the fruit inside hardens to a wood-like consistency. At that stage, the areca nut can only be sliced using a special [[scissors]]-like cutter.{{cn|date=August 2024}} Usually for chewing, a few slices of the nut are wrapped in a [[betel]] leaf along with [[calcium hydroxide]] (slaked lime) and may include [[clove]], [[cardamom]], [[catechu]] resin (''kattha''), or other spices for extra flavouring. Betel leaf has a fresh, peppery taste, but it can also be bitter to varying degrees depending on the variety.{{cn|date=August 2024}} Areca nuts are chewed for their effects as a mild stimulant,<ref>{{cite journal|author1=Gupta Prakash Chandra |author2=Ray Cecily S |title=Epidemiology of betel quid usage |journal=Ann.

Grows wildly in all regions.{{cn|date=August 2024}} In parts of India, [[Sri Lanka]], and southern China, areca nuts are not only chewed along with betel leaf, but are also used in the preparation of [[Ayurvedic Medicine|Ayurvedic]] and [[Chinese herbology|traditional Chinese medicines]].
