What are the main viewpoints of western traditional medicine and how to evaluate them today?

The main points are as follows: 1, "It is believed that diseases are caused by internal disorders of the body, not by the invasion of pathogens and microorganisms." 2. It is considered that "imbalance of yin and yang" is the root cause of the disease, "yang wins is hot, yin wins is cold", "yang deficiency is cold outside, and yin deficiency is internal heat". 3. It is considered that all parts of the body are interrelated. "The body is full of various liquids."

The spread of western medicine in China has a long history. The spread of western learning to the east is an important factor affecting the social transformation in modern China. As an important part of western advanced culture, the spread of medical science in China has not only brought great changes to the medical care system in China, but also changed the lifestyle and even the concept of China people. Since western medicine was introduced into China, it developed under different social and historical conditions with traditional medicine in China, and there are inevitable contradictions between them. Judging from the overall historical development of modern China, western medicine, mainly modern medicine, spread smoothly in China and was finally accepted by all walks of life in China. Since the beginning of the 20th century, it has replaced the traditional medicine in China and become the main part of modern medicine in China.
