Fever is easy to damage yin, forcing body fluid to leak out, eliminating yin and generating body fluid, which is harmful to the body's vaginal fluid. Bing Wang in the Tang Dynasty interpreted it as "the master of forcing water to control the sun". It means to suppress the sun by nourishing yin and strengthening water.
From the pre-Qin anonymous "Su Wenzhizhen's Seventy-four Treatises", selected from Huangdi Neijing: "Those who are cold and hot take yin, and those who are hot and cold take yang, so-called seeking their ownership."
If you use cold medicine to treat the fever, you must treat it from the yin. If you use warm medicine to treat the cold, you must treat it from the yang, which is the so-called cure.

Huangdi Neijing, also known as Neijing, is one of the earliest ancient books in China and the first of the four classics of traditional medicine in China. According to legend, it was made by the Yellow Emperor, hence its name. However, it is generally believed that this book was finally formed in the Western Han Dynasty, and the author was not a single person, but was created by Huang Lao, a doctor in China. As pointed out in "Huai Nan Zi Xiu Wu Xun", the title of "Yellow Emperor" is intended to trace back to the source and worship the original to illustrate the early birth of China medical culture.
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.
Discussing medicine with a holistic view presents a "holistic medical model" of nature, biology, psychology and society. Its basic material comes from the long-term observation of life phenomena by ancient people in 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 divided into two parts: Lingshu and Su Wen. The main contents of Su Wen are as follows: volume 1, volume 2 is the theory of health preservation and yin-yang and five elements, volume 3 is the dirty image, volume 4 is the treatment method, volume 5, volume 6 is the diagnosis method, volume 7, volume 8 is the pathogenesis, and volume 9 ~ 13 is the disease.
The above-mentioned basic theories on human physiology, pathology, diagnosis and treatment highlight the theory of Yin-Yang and Five Elements, the holistic view of the integration of man and nature, the functions of zang-fu organs and qi and blood, the etiology and pathogenesis, and the principles and methods of disease treatment, which are the essence of Su Wen.
