A valerian monograph for the home
Latin Name: Valeriana officinalis

This valerian monograph provides basic information about valerian—common names, usefulness and safety, and resources for more information.
- 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.
Valerian in Health Research
- Knowledge about valerian is limited because there have been only a small number of high-quality studies in people.
Valerian Research Summary
- 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.
- 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.
