Answer: Women's diseases often manifest as menstrual flow varying from heavy to light, occurring either early or late, accompanied by intermittent pain. Physicians generally categorize these simply as "menstrual disorders" without distinguishing whether it is Yin prevailing over Yang or Yang prevailing over Yin; consequently, medication often proves ineffective.

Generally speaking, if Yin Qi (Yin energy) is excessive and overwhelms Yang Qi (Yang energy), the uterus becomes cold, and blood circulation fails. As stated in the *Classic of Internal Medicine*: "When heaven is cold and earth frozen, water condenses into ice." Thus, menstrual flow becomes scanty and delayed. Conversely, if Yang Qi is excessive and overwhelms Yin Qi, blood flows and spills excessively. As stated in the *Classic of Internal Medicine*: "When heaven is hot and earth warm, menstrual water boils and overflows." Thus, menstrual flow becomes profuse and occurs early. One must harmonize Yin and Yang, regulate Qi and Blood, aiming for balance as the ideal state.

If Yang prevails over Yin, resulting in heavy menstruation, use Danggui Yin (Angelica Decoction). This formula suppresses Yang heat, supports Yin fluids, and regulates the meridians.
