A perennial plant of the Valeriaceae family that grows in slightly moist grasslands in mountainous regions (illustration). It has a distinctive fragrance and is cultivated for its ornamental and medicinal properties. The root contains 8% essential oil and is called valerian root. In Japan, it is used as a substitute for the European Valeriana root. The essential oil contains various sesquiterpenes and monoterpenes and has a distinctive odor. It is used as a sedative for mental instability and hysteria. However, for medicinal purposes, Valeriana officinalis is superior to the European Valeriana officinalis L. from which the Valeriana root is taken.

山地のやや湿った草地に生えるオミナエシ科の多年草(イラスト)。特有の香りがあり,観賞用や薬用として栽培される。根には8%の精油が含まれ,吉草根(きつそうこん)と呼び,日本ではヨーロッパのワレリアナ根の代用品とする。精油は種々のセスキテルペンおよびモノテルペンを含み,特有の臭気があり,精神不安定やヒステリーの鎮静薬として用いられる。しかし,このワレリアナ根をとるヨーロッパ産のセイヨウカノコソウV.officinalis L.よりカノコソウの方が薬用としては優良である。
