Huangdi Neijing is divided into Lingshu and Suwen, which is the earliest medical classic in China and one of the four classic works of traditional medicine (the other three are Difficult Classic, Treatise on Febrile Diseases and Shennong Herbal Classic).
Huangdi Neijing is a comprehensive medical work, which establishes the theories of Yin and Yang, five elements, pulse condition, Tibetan image, meridians, etiology, pathogenesis, symptoms, diagnosis, treatment, health preservation and luck. Its basic material comes from the long-term observation of life phenomena in ancient China, a lot of clinical practice and simple anatomical knowledge.
Huangdi Neijing laid the foundation of human physiology, pathology, diagnosis and treatment. It is a medical work with great influence in China and is called the medical ancestor.
Huangdi Neijing is the first summary of ancient Chinese medicine and the only medical masterpiece before the Warring States Period. There are more than 50 kinds of ancient documents cited, of which 29 kinds have titles but the contents are basically preserved. Many people cite ancient documents in the ways of "precise words", "economy", "on words" or "therefore ..." These ancient documents are of great historical significance for understanding the development of traditional Chinese medicine in the pre-Qin period.
