Valerian Root (Valeriana officinalis) by Solgar has calming and relaxing properties for nerves. It also has anti-convulsive properties and is useful in cases of insomnia, tension, anxiety, irritability and muscle spasms. Although some herbal manuals draw attention to long-term high doses of valerian, clinical studies have not shown any problems.
Take 1-3 plant capsules daily, preferably with meals.
