Everyone experiences periods of worry and tension from time to time, especially before an important event like a job interview or an exam. However, if you constantly feel uneasy and tense to the extent that it interferes with your everyday life, you may be suffering from anxiety. According to the U.K. National Health Services' website, NHS Choices, anxiety is usually treated with psychological therapy or anti-anxiety drugs, or a combination of the two. Valerian is an herb that is sometimes used to treat anxiety. However, you should talk to your doctor before using this herb to treat anxiety.
Characteristics
According to the National Center for Complementary and Alternative Medicine, or NCCAM, valerian has been used since at least the time of ancient Greece and Rome to treat a number of ailments, including insomnia, anxiety and depression. Drugs.com notes that there are 200 known species of valerian, but Eurasian Vakeruaba officinalis is the species most often used for medicinal purposes.
Dosage and Administration
Valerian can be taken as a tea, a liquid tincture or in capsules or tablets. The University of Maryland Medical Center, or UMMC, suggests taking 150 mg two to three times daily. This regimen may be followed for up to four weeks. However, this dose and treatment schedule is intended as a guideline only; talk to your doctor about the right dose for you.
Efficacy
UMMC notes that while some studies show valerian works, others show that it is not effective. An evaluation of clinical trial data published October 2006 in the "Cochrane Database of Systematic Reviews" also concluded that there was insufficient evidence to determine the efficacy and safety of valerian compared with placebo for anxiety disorder.
Side Effects
NCCAM notes that short-term use is likely safe for most people but the herb's long-term effects are not known. It may cause side effects, including headaches, stomach upset and fatigue. Valerian may also cause drowsiness and dizziness and in rare cases may trigger an allergic reaction. If you experience difficulty breathing, swelling of the lips and tongue or hives, stop taking this herb and see a doctor immediately.
Contraindications
Talk to your doctor before using valerian if you are taking drugs that have a sedative effect such as muscle relaxants, sleeping tablets or other medicines for anxiety; valerian may heighten their effects and make you feel drowsy. Avoid alcohol while taking this herb, as this may also increase drowsiness.
