What are the risks of taking valerian?

ANSWER

Because valerian may act as a sedative, avoid driving or using machinery for a few hours after you use it. Taking valerian regularly may cause insomnia. It may also result in withdrawal symptoms after you stop using it. Valerian may strongly interact with alcohol and should not be used at the same time as alcohol. Check with a doctor before taking valerian if you have liver problems.

Given the lack of evidence about its safety, valerian is not recommended for children or for women who are pregnant or breastfeeding.
