Valerian is a plant native to Europe and Asia; it also grows in North America.

Valerian has been used medicinally since the times of early Greece and Rome; Hippocrates wrote about its uses. Historically, valerian was used to treat nervousness, trembling, headaches, and heart palpitations.

Today, valerian is used as a dietary supplement for insomnia, anxiety, and other conditions such as depression and menopause symptoms.

The roots and rhizomes (underground stems) of valerian are used to make capsules, tablets, and liquid extracts, as well as teas.

How Much Do We Know?

Knowledge about valerian is limited because there have been only a small number of high-quality studies in people.

What Have We Learned?

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.

What Do We Know About Safety?

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

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

Few side effects have been reported in studies of valerian. 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.

Keep in Mind

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.
