Old age, sickness and death are inevitable in the course of life. How to obtain a healthy life is the common pursuit of all human beings, ancient and modern. This is a big proposition of life. Confucius said, “If you don’t know how to live, how to know how to die.” Therefore, creating a harmonious and beautiful life for body and mind is the true meaning of life. Chinese medicine, which is rooted in Chinese culture, is a study of how to maintain health, how to slow down aging, and how to prevent and treat diseases. First of all, it involves a question of basic understanding of the life process. On a deeper level, in what way did the ancient Chinese sages explore the phenomenon of life? In the absence of all aids, the ancients observed the world with their own physical eyes, experienced the universe with their minds, understood life with their wisdom, and practiced the truth with their lives. They found that the growth and decay of nature surprisingly followed the same law. I Ching: “A Yin and a Yang is called the Way”. The so-called yin and yang refer to the existence of opposing and unifying, opposite attributes in everything. This abstract expression and method of discernment is still inspiring for modern people to understand things. The change of yin and yang can summarize the law of the development of things. This is also true for human beings who live in heaven and earth, which is why the Yellow Emperor’s Classic of Internal Medicine says, “The basis of life is yin and yang. Understanding the program and laws of the evolution of life, conforming to the laws, adapting to changes, and maintaining a balanced state in the midst of changes is precisely the way to obtain physical and mental harmony and health advocated by traditional Chinese medicine. After mastering the law of change of life, we can take advantage of the situation to transform it into a healthy aspect, thus avoiding the emergence of diseases. This is the attitude of Chinese medicine towards life and disease, that is, “not treating the disease but treating the disease before it occurs”, anticipating the opportunity and highlighting the importance of prevention. On the one hand, “prevention is better than cure”: to prevent illness before it occurs, pay attention to the details of daily life and living, and emphasize “dietary discipline and regularity of living and living”, so as to eliminate the hidden dangers of illness; on the other hand, “prevention is better than cure”: to prevent changes when illness occurs, so as to avoid the emergence of illnesses. On the other hand, “preventing disease and preventing gradual change”: preventing disease and preventing gradual change requires doctors to have the insight of knowing the autumn with a single leaf, to grasp the pulse of the change of the disease, to judge the prognosis of the disease, and thus to take measures to block the deterioration of the trend. This is consistent and compatible with the guiding ideology of modern preventive medicine. Nourishing the body and slowing down aging are the concrete embodiment of this idea of preventive health care. Even the treatment of diseases in Chinese medicine is permeated with the idea of treating and preventing changes, rather than merely treating symptoms and resolving superficial phenomena. More importantly, Chinese medicine believes that internal factors play a decisive role in the occurrence of disease, the more abundant the body’s positive energy, the stronger the ability to resist disease, even if the feeling of external disease-causing factors (known as “evil” in Chinese medicine), but also not easy to develop. On the contrary, if a disease occurs, it must be due to the relative weakness of the body’s positive energy. For example, when a cold is prevalent, the same contact with the onset of the person, the body’s defenses are weak easier to infect, strong defenses are not easy to develop; therefore, some people often catch a cold, usually Chinese medicine believes that the surface of the body WeiQi weakness of the key to the problem, replenish the qi and solid defense of the famous formula “Jade Screen Fung San” can solve this kind of disease, by improving the ability to fight disease to reduce the frequency of colds. Frequency. Modern medicine categorizes colds as acute upper respiratory tract infections, which are considered to be the result of respiratory viral infections when the body’s ability to fight disease decreases. The natural history of colds is self-limiting, which means that they can be cured in 5-7 days without medication. However, the frequent occurrence of colds suggests the weakening of the body’s ability to prevent disease. Chinese medicine believes that “a cold that does not wake up will become a labor”, meaning that people who often catch colds, this small disease that can be cured by itself, if not handled correctly, may lead to a more serious health problem in succession. The idea of prevention in Chinese medicine is reflected in the ability to stimulate or improve the body’s own resistance to disease through acupuncture, medicine or health maintenance methods, to achieve mutual harmonization and unity of yin and yang in the human body, a state of dynamic balance, and to maintain harmony with the law of change of the seasons in the natural world. This is exactly what Huang Di Nei Jing emphasizes, “Yin and Yang secret, the spirit is cured”. Is not this state of qi and blood, balance of yin and yang and the World Health Organization advocated the new concept of four-in-one health is not the same realm? TCM’s way of thinking of “treating the disease before it occurs” and regulating the balance of yin and yang is not only a revelation for modern mankind to create a healthy life, improve the ability to resist diseases and solve the problems of sub-health, but more valuable is the fact that the rationale, methodology and prescription of the Chinese medical science accumulated in the past thousands of years have greatly enriched the solutions to the problems. Chinese medicine recognizes things in a macro and dynamic way, emphasizing the connection between the human body and the environment and the influence of external factors such as society, region and climate on human health; the solution to the problem is often a comprehensive and regulating intervention, pursuing fundamental changes in human constitution to adapt to the changes in the environment. These are precisely the subjects that modern medicine has neglected in the past but has been paying increasing attention to in recent years. Therefore, between Chinese medicine and modern medicine, there is no question of mutual substitution, but rather a relationship of mutual complementation, mutual reference and mutual integration. The combination of the two, on the contrary, can provide richer diagnostic and treatment programs to jointly serve human health. In the absence of a higher level of integration at the philosophical level, they can seek localized integration and cooperation, and can solve some specific problems while providing patients with different choices of medical treatment.
