Perennial's Nerve Relief formula supports healthy nervous system function by providing nourishing nervine herbs to the body. When nerves are not adequately nourished, pain and discomfort can occur. Oftentimes this weakness can manifest as burning, tingling, and numbness that may affect the way a person perceives touch as well as shoot, radiating pain in the fingers, toes, hands, or legs. The causes range from an injury, an imbalance in blood sugar levels, statin drugs, and even B-Vitamin deficiencies.
