“Hepatorenal homology” first appeared in the Book of Changes,and the medical concept came from the Yellow Emperor's Inner Canon.The five-element theory puts forward that the liver belongs to wood; the kidney belongs to water,and water creates wood.The kidney is the mother of the liver,and the liver and the kidney have a common source.Essence and blood interchanges.They are interrelated physiologically and pathologically.Longjiang Han's gynecology has attached importance to the theory of “hepatorenal homology” and developed and applied it to guide clinical practice.Professor Han Bailing,the founder of Longjiang Han's gynecology,first proposed the “liver and kidney theory”.As the son of Professor Han Bailing and the representative inheritor of Longjiang Han's gynecology,Professor Han Yanhua,innovatively put forward the theory of “the liver governs the Chongren channel” under the theory and thought guidance of Professor Han Bailing.He developed representative prescriptions such as Bailing Yuyin Decoction,Bushen Huoxue Decoction,and Bailing Tiaogan Decoction and applied them in the treatment of clinical infertility,amenorrhea,and irregular menstruation,achieving good effect.This article focused on the theory and origin of “hepatorenal homology” and expounded on the inheritance and application of the theory by Han's gynecology,embodying the inheritance and innovation of traditional Chinese medicine(TCM) theory and providing a reference for doctors in the field of gynecology.
