Excerpted from Bensky; Chinese Herbal Medicine Materia Medica

• Tonifies the Liver and Kidneys, nourishes the blood, and augments the essence: for patterns of yin or blood deficiency with such signs as dizziness, blurred vision, premature greying of the hair, weakness in the lower back and knees, soreness in the extremities, nocturnal emissions, and insomnia. This is a commonly used herb, as it both tonifies and preserves, and is neither cold, drying, nor too cloying.*
• Expels wind from the skin by nourishing the blood: for wind rash due to blood deficiency.*
