一種芳香性植物。常綠性小型亞灌木，有木質(zhì)莖，葉子灰綠色，花藍(lán)色至藍(lán)紫色。原產(chǎn)于歐洲南部與地中海沿岸地區(qū)。鼠尾草有許多不同的用途與功效，部份同屬植物也有相同的效用，它常常栽培來做為廚房用的香草或醫(yī)療用的藥草，有時(shí)也被稱為庭園鼠尾草、廚房鼠尾草、達(dá)爾馬希亞鼠尾草。在南歐，有時(shí)候也會(huì)種植一些和鼠尾草類似的植物，來做為香草與藥草使用，這些和鼠尾草同屬的植物常會(huì)和真的鼠尾草弄混淆。在歐洲的部分地區(qū)，特別是在巴爾干半島，會(huì)栽種鼠尾草用來萃取精油，不過其他種類的鼠尾草，例如三裂鼠尾草有時(shí)也會(huì)被拿來萃取精油。（中國(guó)進(jìn)出口網(wǎng)）
Sage is a small perennial evergreen sub shrub, with woody stems, grayish leaves, and blue to purplish flowers.
It is native to the Mediterranean region, though it has naturalized in many places throughout the world. It has a long history of medicinal and culinary use, and in modern times as an ornamental garden plant. As a kitchen herb, sage has a slight peppery flavor. The strongest active constituents of sage are within its essential oil, which contains cineole, borneol, and thujone.
