In the theoretical system of traditional Chinese medicine (TCM), the theory of " homogeny" is rich in content and has been extensively discussed by medical scholars throughout history. Various relationships, such as " homogeny of liver and kidney", " homogeny of blood and water", and " homology of ying and wei", have been explored. One relationship that is particularly relevant to the theoretical system of TCM is the connection between dryness and dampness, which is associated with the pathogenesis of many modern diseases. Understanding the relationship between dryness and dampness is crucial in clinical practice. This article examines relevant literature, including classic works like the Huangdi Neijing to explore the theoretical basis for the concept of " homogeny of dryness and dampness". The core connotation of this theory includes the ideas that dryness can generate dampness and dampness can transform into dryness. In clinical practice, it is important for doctors to apply this theory flexibly, addressing dampness when dryness is present and vice versa. For diseases characterized by dampness or dryness pathogens, doctors should consider the coexistence, homology, and mutual transformation of dampness and dryness when conducting syndrome differentiation and treatment. The theory of " homogeny of dryness and dampness" not only enhances the understanding of the etiology and pathogenesis of TCM, but also provides valuable theoretical guidance for modern clinical practice. Further research on this theory will continue to highlight its value in modern clinical applications.

Yuebi Decoction is a classic prescription derived from Synopsis of the Golden Chamber. It has significant clinical efficacy and wide application. Scholars of different dynasties have different opinions on its prescription name and put forward different understandings on the dosage of Ephedrae Herba and Gypsum Fibrosum in the prescription. There is a dispute between relieving exterior prescription and draining dampness prescription in the main syndrome. In this article, it is found that there is no contradiction between relieving exterior and draining dampnes, but they promote each other and play the role of "lifting the pot to uncover the cover". In terms of clinical application, this article introduces the cases of this prescription and its addition and subtraction used in the treatment of diseases of respiratory system, urinary system and other systems in recent years. It is found that clinical use of this prescription is mainly for "sweating and promoting diuresis", which reflects the thought of "treating different diseases with the same treatment" in Traditional Chinese Medicine.

Fangfeng Tongsheng Powder has the effect of dispersing wind heat and internal purging heat. Returning to the origin of Liu Wansu's academic thought, it can be concluded that Fangfeng Tongsheng Powder should be based on the treatment of wind as the symptoms, the treatment of heat as the root, the treatment of both the symptoms and the root, and the double solution of the exterior and the interior. It should be set up for the syndrome of excessive heat and internal and external excess. In recent years, the basic and clinical research directions of this prescription in China mainly include skin diseases, endocrine and metabolic diseases, digestive system diseases, respiratory diseases, etc., while foreign related research focuses on obesity-related metabolic diseases. Studies have found that Fangfeng Tongsheng Powder has the effects of anti-allergy, regulating immunity and improving metabolic disorders. At present, the basic research on Fangfeng Tongsheng Powder in China is relatively insufficient, and the mechanism of Fangfeng Tongsheng Powder needs to be further explored, and more large samples and high-quality RCTs need to be carried out.
