Valerian seems to act like a sedative on the brain and nervous system. Valerian can also help improve sleep when combined with other herbs, including hops, passionflower and lemon balm.

Gamma-aminobutyric acid (GABA) is a neurotransmitter that sends chemical messages through the brain and nervous system. The role of this neurotransmitter is to inhibit or reduce the activity of neurons (nerve cells). Valerenic acid has been found to inhibit the breakdown of GABA in the brain, to produce feelings of calmness and tranquility. Thus, it has been shown to increase GABA levels in the brain which can reduce the amount of time taken to fall asleep, it can also improve the quality of sleep. This is the mechanism by which anti-anxiety medications such as Valium work. Valerian root also contains the antioxidants hesperidin and linarin, which appear to have sedative and sleep-enhancing properties [i] [ii].

Anxiety and psychological stress

The aforementioned mechanism on GABA also helps to calm anxiety via the regulation of nerve cells. Research suggests that valerian root may help ease anxious feelings that occur in response to psychological stress [iii] [iv].

Pain relief and muscle relaxant, menstrual pain

Naturally a sedative and an antispasmodic, Valerian root acts as a powerful muscle relaxant. Valerian appears to work directly on the nervous system as a natural pain reliever [v]. Early research shows that taking 255 mg of valerian three times daily for two menstrual cycles reduces pain and the need for other pain relievers during menstruation [vi].

Valerian can enhance the sedative effects of drugs like benzodiazepines and alcohol, potentially leading to excessive drowsiness. Valerian may also interact with anticoagulant medications and affect the effectiveness of drugs metabolised by the liver.
