Valerian Root Extract
Valerian root (Valeriana officinalis) is commercially grown in Holland and other European countries. Valerian root extract is prepared from dried valerian roots that have been coarsely ground and washed. A liquid extract of the herb is prepared by percolation, concentrated into a paste, and spray dried. Major constituents of Valerian root include valtrates, didrovaltrates, and isovaltrates.1 Herbal extracts are typically standardized to valerenic acid levels.
Traditionally, valerian root has been valued in herbal formulas for relaxation and supporting good sleep.1,2 Valerian root supplementation may reduce the time to fall asleep and improve sleep quality in individuals with sleep problems.3 Valerian root supplementation may decrease restlessness, difficulty with concentration, and impulsiveness in elementary school children and have psychotropic effects to help people with Obsessive Compulsive Disorder (OCD).4,5
