Overview
Valerian (Valeriana officinalis) is an herb native to Europe and parts of Asia. Valerian root has a long history of use as a sedative.
Valerian can grow to be just over 6 feet tall and has a strong odor. It seems to act like a sedative in the brain and nervous system. Valerian has been used as a traditional medicine dating back to ancient Greek and Roman times.
People commonly use valerian for sleep disorders, especially insomnia. Valerian is also used for anxiety, stress, and many other conditions, but there is no good scientific evidence to support most of these uses.
