What the NIH says about the evidence
- NCCIH says the evidence on whether valerian helps with sleep problems is inconsistent.
- In its 2017 guidelines, the American Academy of Sleep Medicine recommended against using valerian for chronic insomnia in adults.
- There is not enough evidence to draw conclusions about valerian for anxiety, stress or other conditions.
Safety
- Because valerian might cause sleepiness, it should not be taken with alcohol or sedatives.
- Stopping suddenly after long use may cause withdrawal symptoms such as anxiety, irritability and trouble sleeping.
- In very rare cases, liver injury has been reported, most often when valerian was combined with other herbs.
