The influence of Shanghanlun on Japanese kampo medicine

Shanghanlun is a classic work in traditional Chinese medicine (TCM), which systematically discusses diagnosis and treatment ideas based on syndrome differentiation and records a large number of highly practical prescriptions. When Shanghanlun was introduced into Japan along with the communication between China and Japan in the Sui and Tang Dynasties, it had a profound influence on the development of Kampo medicine in Japan. By sorting out the works related to Shanghanlun in the medical history literature of Kampo medicine before the Meiji Restoration, this paper discusses the relationship between Shanghanlun and the Koho school of Kampo medicine, as well as the influence of the thought “formula corresponding to pattern identification,” originating from the Koho school, on the development of modern Kampo medicine. The study of Shanghanlun by Kampo medicine nowadays not only attaches great importance to clinical practicality but also has theoretical discussions. It is expected that future medical exchanges between China and Japan will complement each other from the perspectives of both sides and promote the theoretical and clinical development of TCM.
