Its fruits (called areca nuts or betel nuts) are chewed together with slaked lime and betel leaves for their stimulant and narcotic effects. Taxonomy edit 19th century drawing of Areca catechu Common names in English include areca palm, areca nut palm, betel palm, betel nut palm, Indian nut, Pinang palm and catechu.[1] This palm is commonly called the betel tree because its fruit, the areca nut, which are often chewed along with the betel leaf, a leaf from a vine of the family Piperaceae. The species was first published by Carl Linnaeus in his book Species Plantarum on page 1189 in 1753.[2] Description edit Areca catechu is a medium-sized palm tree, growing straight to 20 m (66 ft) tall, with a trunk 10–15 cm (4–6 in) in diameter. The leaves are 1.5–2 m (4.9–6.6 ft) long, pinnate, with numerous, crowded leaflets. Chemical composition edit The seed contains alkaloids such as arecaidine and arecoline, which, when chewed, are intoxicating and slightly addictive. The seed also contains condensed tannins (procyanidins) called arecatannins,[6] which are carcinogenic. The antibacterial activity of the seed has been studied.[7] Uses edit Intensive farming of Areca catechu at a spice plantation in Curti, Goa. Betel nut chewing edit Main articles: Betel nut chewing and Areca nut Areca catechu is grown for its commercially important seed crop, the areca nut, which is the main component of the practice of betel nut chewing. It is popular throughout Southeast Asia, South Asia, Taiwan, Papua New Guinea and some nearby islands, parts of southern China, Madagascar, and the Maldives. The nut itself can be addictive and has direct link to oral cancers.[8][9] Chewing areca nut is a cause of oral submucous fibrosis, a premalignant lesion which frequently progresses to mouth cancer.[10][11] The practice of chewing areca nuts originate from Island Southeast Asia where the plant ingredients are native. The oldest evidence of areca nut chewing is found in a burial pit in the Duyong Cave site of the Philippines (where areca palms were originally native to), dated to around 4,630±250 BP. Its diffusion is closely tied to the Neolithic expansion of the Austronesian peoples. It was spread to the Indo-Pacific during prehistoric times, reaching Micronesia at 3,500 to 3,000 BP, Near Oceania at 3,400 to 3,000 BP; South India and Sri Lanka by 3,500 BP; Mainland Southeast Asia by 3,000 to 2,500 BP; Northern India by 1500 BP; and Madagascar by 600 BP. From India, it was also spread westwards to Persia and the Mediterranean. It was also previously present in the Lapita culture, based on archaeological remains dated from 3,600 to 2,500 BP, but it was not carried into Polynesia.[3] Other uses edit The areca palm is also used as an interior landscaping species. It is often used in large indoor areas such as malls and hotels. It will not fruit or reach full size if grown in this way. Indoors, it is a slow growing, low water, high light plant that is sensitive to spider mites and occasionally mealybugs. In India, the dried fallen leaves are collected and hot-pressed into disposable palm leaf plates and bowls.[12]
