Valerian is well known for its sedative qualities and its ability to relax the central nervous system and the smooth muscle groups. It has been used as a sleeping aid for hundreds of years especially when there is excitation or difficulty in falling to sleep due to nervousness. Over 120 chemical components are found in valerian and although a very complex herb, it has not been found to have any negative side effects with moderate use. At least two double-blind studies have demonstrated that valerian extract can significantly reduce the amount of time it takes people to fall asleep without changing the normal stages of sleep.*
