The cinchona tree (also Cascarilla, Hoja de lucma, Quina) is a native of Central America and the western South America bush family. The name has nothing to do with it China and probably comes from the Quechua word "kina-kina" = "bark of the bark".
The alkaloids and bitter substances contained in the bark are conducive to gastric secretion and are therefore used today primarily as a means of appetite stimulation and indigestion. Previously, the resulting quinine was used as the main drug in the treatment of malaria. Products made from cinchona bark, such as spices or tea, have a characteristic extreme bitter Taste.
Chinese bark spices are used in many special wines, wine-based drinks and liquors to flavoring used, among others at Bitter soda. Bitter Vino. Byrrh, Dubonnet (brand wine), Marsala, as well as many Aperitif-. Liqueur- (for example Lillet ) and Vermouth brands (for example Martini & Rossi with the China Martini).
