Catechu
( or ) is an extract of acacia trees used variously as a food additive, astringent, tannin, and dye. It is extracted from several species of '' Acacia'', but especially '' Senegalia catechu'' (''Acacia catechu''), by boiling the wood in water and evaporating the resulting brew. It is also known as cutch, black cutch, cachou, cashoo, terra Japonica, or Japan earth, and also in Hindi, in Marathi, in Odia, in Assamese and Bengali, and in Malay (hence the Latinized ''Acacia catechu'' chosen as the Linnaean taxonomy name of the type-species Acacia plant which provides the extract). Uses As an astringent it has been used since ancient times in Ayurvedic medicine as well as in breath-freshening spice mixtures—for example in France and Italy it is used in some licorice pastilles. It is also an important ingredient in South Asian cooking paan mixtures, such as ready-made paan masala and gutka. The catechu mixture is high in natural vegetable tannins (which accounts fo ...

Senegalia Catechu
''Senegalia catechu'' is a deciduous, thorny tree which grows up to in height. The plant is called ''khair'' in Hindi, and ''kachu'' in Malay, hence the name was Latinized to "catechu" in , as the type-species from which the extracts cutch and are derived.

Paan
Betel nut chewing, also called betel quid chewing or areca nut chewing, is a practice in which areca nuts (also called "betel nuts") are chewed together with slaked lime and betel leaves for their stimulant and narcotic effects. The practice is widespread in Southeast Asia, Micronesia, Island Melanesia, and South Asia. It is also found among the indigenous peoples of Taiwan, Madagascar and parts of southern China. It has also been introduced to the Caribbean in colonial times. The preparation combining the areca nut, slaked lime, and betel leaves is known as a betel quid (also called ''paan'' or ''pan'' in South Asia). It can sometimes include other substances for flavoring and to freshen the breath, like coconut, dates, sugar, menthol, saffron, cloves, aniseed, cardamom, and many others. The areca nut itself can be replaced with or chewed with tobacco, and the betel leaves can be excluded altogether. The preparation is not swallowed, but is spat out afterwards. It results ...

White Cutch
Gambier or gambir is an extract derived from the leaves of '' Uncaria gambir'', a climbing shrub native to tropical Southeast Asia. Gambier is produced in Indonesia and Malaysia where it was an important trade item into the late nineteenth century. It can be used as a tanning agent, a brown dye, a food additive and as herbal medicine. Also known as pale catechu, white catechu or Japan Earth, it is often confused with other forms of catechu. History Gambier production began as a traditional occupation in the Malay archipelago. By the middle of the seventeenth century, it was established in Sumatra and in the western parts of Java and the Malay peninsula. It was initially used as medicine and chewed with betel. Local Chinese also began to use gambier to tan hides. Chinese first got involved in gambier production at Riau, using coolie labor and growing black pepper as a supplemental crop. Bugis merchants traded the gambier for rice from Java and Siam, helping the Bugis to become a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gutka
Gutka, ghutka, guṭkha or betel quid is a chewing tobacco preparation made of crushed areca nut (also called betel nut), tobacco, catechu, paraffin wax, slaked lime (Calcium hydroxide) and sweet or savory flavourings, in India, Pakistan, other Asian countries, and North America. It contains carcinogens, is considered responsible for oral cancer and other severe negative health effects and hence is subjected in India to the same restrictions and warnings as cigarettes. Highly addictive and a known carcinogen, gutkha is the subject of much controversy in India. Many states have sought to curb its immense popularity by taxing sales of gutkha heavily or by banning it. Gutka is manufactured in the sub-continent and exported to a few other countries, often marketed under the guise of a "safer" product than cigarettes and tobacco. Reported to have both stimulant and relaxation effects, it is sold throughout South Asia and some Pacific regions in small, individual-sized foil packets/sa ...

Tannin
Tannins (or tannoids) are a class of astringent, polyphenolic biomolecules that bind to and precipitate proteins and various other organic compounds including amino acids and alkaloids. The term ''tannin'' (from Anglo-Norman ''tanner'', from Medieval Latin ''tannāre'', from ''tannum'', oak bark) refers to the use of oak and other bark in tanning animal hides into leather. By extension, the term ''tannin'' is widely applied to any large polyphenolic compound containing sufficient hydroxyls and other suitable groups (such as carboxyls) to form strong complexes with various macromolecules. The tannin compounds are widely distributed in many species of plants, where they play a role in protection from predation (acting as pesticides) and might help in regulating plant growth. The astringency from the tannins is what causes the dry and puckery feeling in the mouth following the consumption of unripened fruit, red wine or tea. Likewise, the destruction or modification of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uncaria Gambir
''Uncaria gambir'', the gambier or gambir, is a species of plant in the genus '' Uncaria'' found in Southeast Asia, mainly Malaysia and Indonesia. Extract Gambier extract is used or has been used as a catechu for chewing with areca and betel, for tanning and dye A dye is a colored substance that chemically bonds to the substrate to which it is being applied. This distinguishes dyes from pigments which do not chemically bind to the material they color. Dye is generally applied in an aqueous solution and ...ing, and as herbal medicine. Gambier extract was also used by native people as a medical treatment or prevention of diseases that were believed to be spread by the now obsolete medical theory of miasma. The Indians invented ''paan'', a gambir paste, that was believed to help prevent miasma; it was considered as the first antimiasmatic application. The gambir tree is found in Southern India and Sri Lanka. References * * gambir {{Cinchonoideae-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fishing Net
A fishing net is a Net (device), net used for fishing. Nets are devices made from fibers woven in a grid-like structure. Some fishing nets are also called fish traps, for example #Fyke nets, fyke nets. Fishing nets are usually meshes formed by knotting a relatively thin thread. Early nets were woven from grasses, flaxes and other fibrous plant material. Later cotton was used. Modern nets are usually made of artificial polyamides like nylon, although nets of organic polyamides such as wool or silk thread were common until recently and are still used. History Fishing nets have been used widely in the past, including by stone age societies. The oldest known fishing net is the net of Antrea, found with other fishing equipment in the Karelian town of Antrea, Grand Duchy of Finland, Finland, in 1913. The net was made from willow, and dates back to 8300 BC. Recently, fishing net sinkers from 27,000 BC were discovered in Korea, making them the oldest fishing implements discovered, ...

Astringent
An astringent (sometimes called adstringent) is a chemical that shrinks or constricts body tissues. The word derives from the Latin ''adstringere'', which means "to bind fast". Calamine lotion, witch hazel, and yerba mansa, a Californian plant, are astringents. Astringency, the dry, puckering or numbing mouthfeel caused by the tannins in unripe fruits, lets the fruit mature by deterring eating. Ripe fruits and fruit parts including blackthorn (sloe berries), ''Aronia'' chokeberry, chokecherry, bird cherry, rhubarb, quince and persimmon fruits (especially those which are unripe), banana skins (or unripe bananas), cashew fruits and acorns are astringent. Citrus fruits, like lemons, are somewhat astringent. Tannins, being a kind of polyphenol, bind salivary proteins and make them precipitate and aggregate, producing a rough, "sandpapery", or dry sensation in the mouth. The tannins in some teas, coffee, and red grape wines like Cabernet Sauvignon and Merlot produce mild ast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
