Areca nut

The areca nut (/ˈærᵻkə/ or /əˈriːkə/) is the seed of the areca palm (Areca catechu), which grows in much of the tropical Pacific, Asia, and parts of east Africa. It is commonly referred to as betel nut, as it is often chewed wrapped in betel leaves (paan). The term areca originated from a South Asian word during the 16th century, when Dutch and Portuguese sailors took the nut to Europe. The habit has many harmful effects on health. The International Agency for Research on Cancer concluded after reviewing the published medical research that chewing areca nut is carcinogenic to humans. Various compounds present in the nut, most importantly arecoline (the primary psychoactive ingredient), contribute to histologic changes in the oral mucosa. As with chewing tobacco, its use is discouraged by preventive efforts, such as awareness of the risks of chewing buai.

Description

The areca nut is not a true nut, but rather a fruit categorized as a drupe. 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 (known as aḍakattera in Telugu, adake kattari in Kannada,bajjeai in Tulu, adakitta [अडकित्ता] in Marathi, puwak [පුවක්] in Sinhala, shupari [সুপারি] or jaanti in Bengali, adakka അടക്കാ in Malayalam, pakku (பாக்கு) in Tamil, sarautaa in Hindi, Khilikaati in Odia, sudi in Gujarati) and Su'aro سوئڙو in Sindhi.
