Wang Jiang Nan Zi, also known as Coffee Senna or Cassia occidentalis Seed, is the dried mature seed of a leguminous plant widely used in Traditional Chinese Medicine (TCM) for its heat-clearing, liver-pacifying, bowel-moistening, and detoxifying properties. With a slightly bitter taste and cold nature, it is particularly useful in formulas addressing red or painful eyes, dizziness, constipation, and symptoms of liver fire or internal heat. It is often included in liver-cleansing teas, vision support blends, and herbal laxatives.
