Daily mental stress and occasional tension can cause the nerves to become tired and fatigued. The nerve supporting herbs in Herbal Sleep feed and strengthen the nerves and allow the body to handle daily stress effectively. Nervine herbs also have a calming, quieting effect on the nerves. Herbal Sleep contains a synergistic blend of herbal ingredients carefully selected for their quality and overall effectiveness in promoting restful sleep. In one study, a combination of hops and valerian improved sleep quality. Other combinations that included hops have been shown to help support the gall bladder and help promote bladder and urinary function. Valerian has been shown to help maintain smooth muscles and produce relaxation in mice. Passion flower increased sleeping time in both rats and mice. Take 2 capsules daily with a meal.
