Valerian is a perennial flowering plant in the honeysuckle family which is native to Europe and parts of Asia. In North America valerian has escaped gardens and has become naturalized in many area of Canada and the USA. The genus name "valeriana" comes from the medieval Latin name, possibly derived from the Latin word 'valere' meaning to be healthy in reference to the plant's medicinal uses in nervousness and hysteria. The species name "officinalis" means medicinal in reference to herbal/medicinal uses. The amino acid valine is named after this plant.
The plant yields about 1% of an essential oil from the roots which is used in perfumery to provide a 'mossy' aroma. Crude extract of valerian root is sold as a dietary supplement in the form of capsules. Plants are cultivated in Europe for producing an over-the-counter tranquilizer.
Within the realm of naturopathic medicine and folklore, valerian is a well-known and frequently used medicinal herb that has a long and proven history of efficacy. It is noted especially for its effect as a tranquillizer and nervine, particularly for those people suffering from nervous overstrain. Valerian has been shown to encourage sleep, improve sleep quality and reduce blood pressure. Valerian is also used internally in the treatment of painful menstruation, cramps, hypertension, and irritable bowel syndrome. Externally, valerian is used to treat eczema, ulcers and minor injuries.

Valerian is a perennial which can grow 90cm to 150cm tall featuring a clump of deeply lobed basal foliage from which a tall and slender stem grows topped by highly fragrant pink, or white, flowers. Leaves of the valerian plant are odd-pinnate, each leaf having seven to ten pairs (plus terminal) of serrate, lanceolate leaflets. Leaves are aromatic when bruised. Flowers grow in branched panicles growing 5cm to 10cm wide. The flowers are frequently visited by many fly species, especially hoverflies of the genus Eristalis. It is consumed as food by the larvae of some Lepidoptera (butterfly and moth) species including the grey pug.
