Valerian is an herb that is primarily used as a supplement to help treat insomnia. Although it is not exactly clear as to how it works, it may affect a certain brain chemical that produces a naturally calming effect. If you have epilepsy or liver disease, talk to your healthcare provider before taking it. Possible side effects of valerian include headaches, excitability, and morning drowsiness.

How Does Valerian Work?It is not exactly clear how it works to treat insomnia or other health conditions. There are a variety of different active compounds in valerian, and researchers are not sure which of these compounds are responsible for the sedative-like properties of the supplement. Some of the compounds seem to increase gamma aminobutyric acid (GABA), a chemical in the brain that has a naturally calming effect.
Is It Effective?Some studies have shown that valerian is effective at treating insomnia, although further research is needed to establish how best to safely and effectively use the supplement for this condition. There is not enough evidence to recommend it for other uses at this time.
