Zhang Zhongjing, a famous Chinese medical scientist, is called the sage of medicine. Zhang Zhongjing (about 150-219 years) was a figure in the late Eastern Han Dynasty, from Nanyang, Henan Province, also known as Zhang Ji and Zhang Changsha.
According to records, Zhang Zhongjing once worked as the chief of Changsha. Zhang Zhongjing was fond of medicine when he was young. He studied medicine with Zhang bozu when he was young. After years of hard research and clinical practice, he became an outstanding physician in the history of Chinese medicine. Zhang Zhongjing lived in the last years of the Eastern Han Dynasty, which was an extremely turbulent era in Chinese history. There were frequent wars, epidemics, displacement of the people, and the people could not survive. Zhang Zhongjing's family was originally a big one, with a population of more than 200. Since the early years of Jian'an, less than 10 years ago, two-thirds of the people died of epidemic diseases, of which 7% died of typhoid fever. In the face of the plague, Zhang Zhongjing was very sad and indignant. During his stay in Changsha, he sat in the lobby to practice medicine while taking care of political affairs. He treated the people and saved many people's lives.
Zhang Zhongjing assiduously studied the Neijing, extensively collected medical prescriptions, and wrote the great book treatise on febrile diseases. The principle of syndrome differentiation and treatment established by it is the basic principle of TCM clinical practice and the soul of TCM. In terms of prescription, treatise on febrile diseases has also made great contributions, created many dosage forms and recorded a large number of effective prescriptions. The dialectical treatment principle of the six meridians established by him has been highly praised by medical experts of all ages. This is the first medical monograph from theory to practice in China, which establishes the principle of syndrome differentiation and treatment. It is one of the most influential works in the history of Chinese medicine. It is also a necessary classic work for post scholars to study traditional Chinese medicine. It is widely valued by medical students and clinical doctors. Zhang Zhongjing got the syndrome characteristics through various diagnosis (four diagnosis by watching, listening, asking and feel the pulse) and doctor's analysis (syndrome differentiation analysis), and then he could make a prescription. It is built on the basis of profound medical theory and strict dialectical analysis, which completely negates the subjective diagnosis method of judging the nature of disease and treatment method only by symptoms, and also establishes another important pillar theory of traditional Chinese Medicine - "syndrome differentiation and treatment" principle.
In his later years, Zhang Zhongjing lived in seclusion, devoted himself to the study of medicine, and wrote medical books. At last, he wrote an epoch-making clinical medicine masterpiece treatise on febrile diseases, a total of 16 volumes. Later, it was compiled into two books, treatise on Febrile Diseases and synopsis of the golden chamber.
