Zhu Danxi's Chinese Medicine Culture Zhu Danxi, a famous medical scientist in the Yuan Dynasty, was born in Chi'an, Yiwu. He was one of the four great doctors in the Jin and Yuan Dynasties and was praised as "a great master of medicine in the history of Chinese medicine who is proficient in both medical theory and medical theory". In China, his theories of "excess yang and insufficient yin", "phase fire theory" and "theory of four injuries of qi, blood, phlegm and depression" enriched and developed the content of Chinese medicine, and there is a saying that "Danxi is the ancestor of miscellaneous diseases". In addition, his prescriptions such as Dabuyin Pills, Yanshou Pills, Yueju Pills, Baohe Pills, Ermiao Powder, Zuojin Pills, Huqian Pills and Shangzhongxia Tongyong Tongfeng Fang are still commonly used in clinical practice today. His emphasis on prevention before illness, protection of positive energy and psychological adjustment still affects the health of contemporary people. Zhu Danxi's Chinese medicine culture also has a great influence internationally, especially in the 15th century AD, when Danxi's theory was introduced to Japan and developed into the earliest school of Japanese Kampo medicine, the "Later School", which guided Kampo medicine for three hundred years. Zhu Danxi was honored as the "Medical Saint" and the "Danxi Academy" is still used today. The Zhu Danxi Chinese medicine culture derived from him has had a significant impact on the progress of ancient and modern Chinese and foreign medicine.
