Mechanism of action of valerian root extract
Valerian’s effects on the central nervous system (CNS) have been attributed variously to valepotriates, their breakdown products(baldrinals), valerenic acid, valerenal and valeranone, and other constituents in the essential oil. Multiple compounds may work together synergistically to produce a sedative effect. Animal studies show that valerenic acid may inhibit enzymes that break down GABA, thus increasing GABA levels and producing a CNS-depressing effect. An in vitro study to elucidate the sedative activity of valerian demonstrate that valerian extract LI 156 acted upon the melatonin receptor in a dose-dependent manner. The exact mechanism of action of valerian is still not clear. Valerian contains small amounts of GABA, but this chemical does not cross the blood-brain barrier. Therefore, taking GABA in a supplement form is not effective as valerian root. It is the synergistic effects of the ingredients within the root of valerian extract
