According to herbal medicine, Valerian acts as a sedative, antispasmodic and diuretic. Called the "Valium of the nineteenth century" valerian is recognized world wide for its relaxing effect on the body. In Europe, it is often used to control anxiety, insomnia and excitability. Valerian does not have their unpleasant side effects (except it doesn't taste very good) and it is not addictive. Valerian has a synergistic effect with alcohol. For centuries, valerian has been used to relieve muscle cramps related to stress, menstrual cramps, and premenstrual syndrome PMS. Although valerian has been widely studied, how this herb works is still not known.

Caution: In extremely high dosages, valerian may cause paralysis and a weakening of the heartbeat. So do not exceed recommended dosage.

Valerian was used frequently in the United States before modern sleeping pills.
