'''Medicinal Uses & Benefits of Valerian''' | |||

:By Tracey Roizman, D.C. (Demand Media) | |||
Valeriana, a genus of perennial flowering plant native to Europe, North America and South America, contains several species with potentially medicinal benefits, collectively referred to as valerian. Herbalists have used valerian, a mainstay in traditional medicine, since 200 A.D., according to the University of Maryland Medical Center. Consult your doctor about the appropriate use of valerian. | |||
:Anti-Anxiety | |||
Valerian helps alleviate symptoms of anxiety, according to a study published in the July 2010 issue of the journal "Phytomedicine." In the laboratory animal study, two valerian extracts showed the ability to bind to receptors for GABA, one of the brain's calming neurotransmitters, in a manner similar to that of benzodiazepine drugs. Doses of 3 mililiters per kilogram of body weight of whole valerian root extract and 3 miligrams per kilogram body weight of valerenic acid, an extract of valerian, both reduced anxious behavior. Results of this preliminary study support valerian's traditional use as a natural method to manage mild anxiety. | |||
:Sleep Improvement | |||
A type of valerian known as Valeriana wallichii, may help you sleep better, according to a laboratory animal study published in the July 2012 issue of the journal "Phytomedicine." Participants who took doses of 200 and 300 milligrams per kilogram of body weight fell asleep faster and woke up fewer times during the night. Total sleep time increased and brain levels of the neurotransmitters norepinephrine and serotonin were improved. Additionally, slow brain waves during non-REM sleep increased, indicating improved sleep quality. Researchers concluded that Valeriana wallichii's sleep benefits may be related to its effects on levels of neurotransmitters and certain other amino acids in the brain. | |||
Liver Protection | |||
A form of valerian known as Valeriana jatamansi, an herb used in traditional Indian herbal medicine, may offer liver-protective benefits, according to a study published in the December 2010 issue of the journal "Methods and Findings in Experimental and Clinical Pharmacology." In the laboratory animal study, supplementation with Valeriana jatamansi for nine weeks reduced elevated liver enzymes. Researchers note that the herb has also been shown to decrease overactive cell reproduction in response to chemical irritants and conclude that Valeriana jatamansi shows potential as a natural treatment for liver cirrhosis. Further studies are needed to determine if these preliminary benefits extend to humans. | |||
:Antioxidant Benefits | |||
Antioxidants help protect cells from the damaging effects of toxins and cellular waste products. Antioxidant activity of valerian was demonstrated in a test-tube study published in the January 2013 issue of the "Pakistan Journal of Pharmaceutical Sciences." In the study, levels of valerenic acid and valepotriates, valerian's active constituents that provide antioxidant benefits, were compared between Valeriana officinalis and two other plants that contain valerenic acid -- Valeriana sisymbriifolia and Nardostachys jatamansii. Results showed that the compounds were present in all three plants and that Valeriana officinalis contains the highest levels, providing the greatest antioxidant activity. | |||
