VALERIAN

Valerian is the Valeriana genus of plants of the family Valerianaceae having small fragrant flowers of white, purple or pink. The root was formerly used in medicine as a nerve sedative and antispasmodic. Common Valerian (Valeriana officinalis) is a perennial herb with a massive root system and a short rhizome, which bears angular, erect, furrowed, usually unbranched stems. It is native to Britain and Europe, where it grows on rough grassy and bushy places, often on damp soils.
