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 name Valerian comes from the Latin word valere, meaning "to be strong or healthy", generally thought to refer to its medicinal use, though many references suggest that it also refers to the strong odor.

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.

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 species including Grey Pug.

Valerian has uses in herbal medicine as a sedative. It has in the past been recommended for epilepsy but that has not been supported by modern research. The main current use of valerian is as a remedy for insomnia. Large doses are known to cause withdrawal symptoms when stopped, as it is mildly addictive. Those with liver disease are advised not to use valerian. Valerian is the source of valeric acid.

The volatile oils that form the active ingredient are extremely pungent, somewhat reminiscent of well-matured cheese or well-matured milk. Valerian tea should not be prepared with boiling water, as this may drive off the lighter oils.

An unusual feature of valerian is that the dried root affects the domestic cat in a similar way as that of catnip. If valerian root is left in a place to which cats have access, they will roll in it, drool on it and chew it. Burmese cats are attracted to the dried herb and will deliberately destroy containers to obtain it. However, some cats will not go near valerian root.

Rats are also attracted to valerian.

Valium neither contains nor is derived from valerian. [1]
