Valerian (herb)

Valerian (Valeriana officinalis, Valerianaceae) is a hardy perennial flowering plant, with heads of sweetly scented pink or white flowers. This "sweet" smell is quite overpowering when the flower is placed into a vase. The flowers are in bloom from June to September. Valerian was used as a perfume in the sixteenth century.

Native to Europe and parts of Asia, Valerian has been introduced into North America. It is consumed as food by the larvae of some Lepidoptera (butterfly and moth) species including Grey Pug.

Other names used for this plant include garden valerian (to distinguish it from other Valeriana species), garden heliotrope (although not related to Heliotropium) and all-heal.

Valerian, in Pharmacology and Phytotherapic Medicine, is the name of a herb or dietary supplement prepared from roots of the plant, which, after maceration, trituration, dehydration processes, are conveniently packaged, usually into capsules, that may be utilized for certain effects including sedation and anxiolytic effect.
