The ancient Yellow Emperor's Inner Canon noted the role of the liver in gynecology. It is mentioned that in a woman's life, there is excess of qi but not enough of blood, and the number of blood is taken away. This sentence reveals the relationship between the physiological characteristics of women and the liver, that is, the pathological characteristics of women are mainly emotional and blood diseases, and these two are particularly closely related to the liver. The two basic functions of the liver – the main storage of blood and the main drainage – are crucial for women's physiological processes such as menstruation, childbirth, and lactation. The liver has the function of regulating and releasing blood, as well as regulating emotions. Women's emotions are prone to fluctuations, and if the liver's blood storage and release functions are normal, their emotions are easy to maintain smoothness and calmness, avoiding anger or excessive depression.
古老的《黄帝内经》就注意到了肝在妇科中的作用。提到：“妇人之生，有余于气，不足于血，以其数脱血也。”这句话揭示了女子生理特点与肝的关系，即女子病理特点主要为情志病和血病，而这两者与肝的关系尤为密切。肝的两个基本功能——主藏血和主疏泄，对于女子的经孕产乳等生理过程至关重要。肝主疏泄还有调畅情志的作用，女性情绪易波动，肝的藏血和疏泄功能正常，则情绪易于保持畅达平和，避免暴怒或过度抑郁。
