Valerian root is an herb from the plant Valeriana officinalis, which is found growing in Europe, Asia and North America. The root of the plant is pressed into fresh juice or freeze-dried to form powder and used as an herbal remedy, according to the University of Maryland Medical Center. Valerian root is sold as a dietary supplement; therefore, there are no long-term studies on its use. Valerian is also known as all-heal, garden heliotrope and amantilla. As with any herb or herbal supplement, those considering taking valerian root should consult with a health care professional.
History
Valerian has been used as a medicinal herb dating back to ancient China, Greece and Rome. During the 2nd century, its therapeutic uses were described by Hippocrates and Galen, a prominent Greek physician, prescribed it for insomnia, according to the Office of Dietary Supplements. The use of valerian root became very popular in Europe in the 16th and 17th centuries, when it was used to treat nervousness, headaches and trembling. During World War II, the British used it for stress relief during the air raids.
Uses
Valerian root is primarily used as a sleep aid for those suffering from insomnia. It does not take effect immediately and must be taken continuously for several days to several weeks before any results are noticed, according to MedlinePlus. Valerian root is also used to treat anxiety, headaches, irregular heartbeat, stomach cramps, joint pain and depression. Some practitioners suggest taking valerian root to aid in the cessation of smoking or to ease congestion, according to the American Cancer Society. Valerian has a sharp odor and is also used as a flavor in foods and some drinks, such as root beer.
Safety and Effectiveness
Valerian root has been found to be GRAS, or generally recognized as safe, by the FDA, according to the University of Maryland Medical Center. Valerian root is classified as being possibly effective for insomnia by the Natural Medicines Comprehensive Database, according to MedlinePlus. Several small studies were performed on its effectiveness, but all had inconclusive results. Valerian root is considered safe for short-term therapy of 28 days, but more studies are needed to determine valerian root's effectiveness and safety over the long-term.
Dosing
For insomnia, MedlinePlus recommends 400 to 900 mg of dry powdered Valerian root extract taken 30 minutes to 2 hours prior to bedtime. Valerian root can also be taken as in a tea. Valerian root in any of its forms should not be taken more than three times per day.
Precautions
Side effects of valerian root can include headache, itching, dizziness and stomach upset. Those taking valerian root may also experience morning-after tiredness, according to the National Center for Complementary and Alternative Medicine. Women who are pregnant or breastfeeding should not take valerian. Valerian root should not be used with other herbs that cause sleepiness such as St. John's wort, kava and melatonin. Those considering taking valerian root should discuss possible side effects with their doctors prior to use.
