Galangal

Galangal, Malay lengkuas, Mandarin (Traditional: 南薑/Simplified: 南姜, also termed as: T:高良薑/S:高良姜), Cantonese lam keong (藍薑, also known as blue ginger), is a rhizome with culinary and medicinal uses, best known in the west today for its appearance in Southeast Asia cuisine but also common in recipes from medieval Europe. Though it resembles ginger in appearance, it tastes little like ginger. In its raw form, galangal has a soapy, earthy aroma and a pine-like flavor with a faint hint of citrus. It is available as a powder from vendors of Oriental spices and is also available whole, cut or powdered from vendors of herbs. A mixture of galangal and lime juice is used as a tonic in parts of Southeast Asia. It is said to have the effect of an aphrodisiac, and act as a stimulant. Galangal is also known as laos (its Indonesian name), galanggal, and, somewhat confusingly, galingale, which is the name for several unrelated plants of the Cyperus genus of sedges, also with aromatic rhizomes.
