The Yellow Emperor's Internal Classic, a classic version in classical Chinese and modern vernacular.
"Huangdi Neijing" is divided into two parts: "Lingshu" and "Suwen". It is the earliest medical classic in China and one of the four classics of traditional medicine (the other three are "Difficult Classic", "Treatise on Febrile and Miscellaneous Diseases" and "Shen Nong's Materia Medica").
"Huangdi Neijing" is a comprehensive medical book. Based on Huang-Lao Taoist theory, it established the "Yin-Yang Five Elements Theory", "Pulse Theory", "Zangxiang Theory", "Meridian Theory", "Etiology Theory", "Pathogenesis Theory", "Disease", "Diagnosis", "Treatment" and Theories such as "Health Preservation" and "Luck Science" discuss medicine from a holistic perspective, presenting a "holistic medical model" of nature, biology, psychology, and society (according to the research of modern scholars, it is believed that the traces of Huang-Lao Taoism in the present edition are from the Taoist priest Wang Bing in the Sui and Tang Dynasties).
The Yellow Emperor's Inner Canon is the oldest and most influential medical book in China, and is respected by later generations as the "ancestor of medical schools." The content of "Huangdi Neijing" is very extensive. In addition to medicine, it also records ancient philosophy, astronomy, meteorology, phenology, biology, geography, mathematics, sociology, psychology, phonology, etc. It infiltrates these knowledge and results into medicine, making the book a multi-disciplinary work with medicine as the main body.
