Valerian (Valeriana officinalis) is a perennial flowering plant native to Europe and Asia. In the summer when the mature plant may have a height of 1.5 metres, it bears sweetly scented pink or white flowers that attract many fly species, especially hoverflies of the genus Eristalis.
Medicine is made from the root. Valerian is most commonly used for sleep disorders, especially the inability to sleep (insomnia). Valerian is also used orally for anxiety and psychological stress, but there is limited scientific research to support these uses.
To make Valerian root tea, steep a teaspoon of the dried root in one cup of hot water for 10 minutes (roots need to steep longer than the aerial parts of a plant). Strain and drink. If you are using this as a sleep aid, consume 30 to 60 minutes before bedtime.
