Betel<unk>  merchant.Betel<unk>  saleswoman (Vanimo, Papua New Guinea) The<unk>  is not a true<unk> , 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<unk>  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<unk>  can only be sliced using a special scissors-like cutter. Usually for chewing, a few slices of the<unk>  are wrapped in a betel leaf along with calcium hydroxide (slaked lime) and may include clove, cardamom, catechu (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.<unk> s are chewed with betel leaf for their effects as a mild stimulant, causing a warming sensation in the body and slightly heightened alertness, although the effects vary from person to person. The<unk>  contains the tannins<unk> tannin and gallic acid; a fixed oil gum; a little terpineol; lignin; various saline substances; and three main alkaloids—arecoline,<unk> idine, and guvacine—all of which have vasoconstricting properties. The betel leaf chewed along with the<unk>  contains eugenol, another vasoconstrictor. Tobacco leaf is often added to the mixture, thereby adding the effect of nicotine. In parts of India, Sri Lanka, and southern China,<unk> s are not only chewed along with betel leaf, but<unk> lso used in the preparation of Ayurvedic and traditional Chinese medicines. Powdered<unk>  is used as a constituent in some dentifrices. Other traditional uses include the removal of tapeworms and other intestinal parasites by swallowing a few teaspoons of powdered<unk> , drunk as a decoction, or by taking tablets containing the extracted alkaloids. According to traditional Ayurvedic medicine, chewing<unk>  and betel leaf is a good remedy against bad breath.
