The evidence on whether valerian is helpful for sleep problems is inconsistent.

There’s not enough evidence to allow any conclusions about whether valerian can relieve anxiety, depression, or menopausal symptoms.

Side Effects Of Valerian

Studies suggest that it is generally safe for use by most healthy adults for short periods of time.

No information is available about the long-term safety or the safety in children younger than age 3, pregnant women, or nursing mothers.

Few side effects have been reported in studies. Those that have occurred include headache, dizziness, itching, and digestive disturbances.

Because it is possible (though not proven) that valerian might have a sleep-inducing effect, it should not be taken along with alcohol or sedatives. 


Tell all your health care providers about any complementary or integrative health approaches you use. Give them a full picture of what you do to manage your health. This will help ensure coordinated and safe care.
