The palm is originally native to the Philippines , [ 1 ] [ 2 ] but was carried widely through the tropics by the Austronesian migrations and trade since at least BCE due to its use in betel nut chewing.
It is not to be confused with betel Piper betle leaves that are often used to wrap it. The practice of betel nut chewing, often together with other herbs as a stimulant drug , dates back thousands of years, and continues to the present day in many countries. Betel nut chewing is addictive due to the presence of the stimulant arecoline , and causes adverse health effects, mainly oral and esophageal cancers , and cardiovascular disease. When chewed with additional tobacco in its preparation like in gutka , there is an even higher risk, especially for oral and oropharyngeal cancers.
With tobacco it also raises the risk of fatal coronary artery disease , fatal stroke , and adverse reproductive effects including stillbirth , premature birth , low birth weight. The term areca originated from Dravidian languages , cognates of which are: [ 3 ] [ 4 ].
The terms dates back to the 16th century when Dutch and Portuguese sailors took the nut from India to Europe. The areca nut is not a true nut , but rather the seed of a fruit categorized as a berry.
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. 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.
