Which dynasty did Chinese medicine originate in

The origin of Chinese medicine is very early. In the Yellow Emperor's Classic of Internal Medicine, which was written between the Warring States period and the Tai Han period, the theoretical system of Chinese medicine has been basically formed. At the end of the Eastern Han Dynasty, Zhang Zhongjing's "Treatise on Typhoid Miscellaneous Diseases" summarized the principles of TCM dialectical treatment. Since then, the theory and practice of Chinese medicine have continued to develop. Taking the division of Chinese medicine as an example, "Zhou Li - Heavenly Officials" recorded that at that time, the court doctors were only divided into food doctors (equivalent to dietitians), disease doctors (equivalent to internal medicine), ulcer doctors (equivalent to traumatology) and veterinarians. To the Ming Dynasty, the Imperial Hospital set up thirteen sections, namely, large square pulse (equivalent to internal medicine), typhoid (i.e., fever), women, small square pulse (equivalent to pediatrics), mouth and teeth, throat, eyes, sores, bone (or bone), Jinchuang, acupuncture, massage, Zhuyu. At the beginning of the Qing Dynasty, the small square pulse was further divided into the pox and rash section. However, in modern times, due to the importation of Western medicine and the old government's discrimination and exclusion of Chinese medicine, the development of Chinese medicine was seriously hindered and stagnated. After the founding of New China, the obstacles can be eliminated. 1950s, the establishment of Chinese medicine hospitals in the country, the founding of schools of higher education in traditional Chinese medicine, and advocate the combination of Chinese and Western medicine to develop Chinese medicine. 80s, further proposed the modernization of traditional Chinese medicine, modern science, including modern medical theories and methods, multidisciplinary, multi-strategy research and development of traditional Chinese medicine.
