Why Do People Use Valerian?

People Get Valerian because of :

The use of valerian is supported by some evidence from clinical studies. The problem with many of the studies, however, is they've generally been small, used different amounts of valerian for varying lengths of time, or had problems with the study design, making it impossible to form a conclusion about the effectiveness of valerian.

insomnia
Valerian appears to be less effective than prescription sleep medication. One possible advantage of valerian, however, is that it may not have as much of a "hangover" effect on mental or physical functioning the following day. Also, people taking sleeping pills sometimes have a temporary worsening of insomnia when they are discontinued, an effect that hasn't been reported with valerian.

 Anxiety
Valerian is also used for anxiety, although there's insufficient evidence that it's effective.
