Valeriana Officinalis
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.
Uses
Valerian is used against sleeping disorders, restlessness and anxiety, and as a muscle relaxant. Valerian seems only to work when taken over longer periods (several weeks), though many users find that it takes effect immediately. Some studies have demonstrated that valerian extracts interact with the GABA and benzodiazepine receptors. Valerian is also used traditionally to treat gastrointestinal pain and spastic colitis.
