Chinese medicine has a long history, extensive and profound. Before the birth of science, it had spread in China for thousands of years to serve the people. Personally, I think that the method of keeping in good health in Chinese medicine and the method of keeping in good health advocated by modern science belong to two completely different theoretical systems and methodologies. If you agree with the former, don't judge by the latter's theory. Frankly speaking, the theoretical system and practical methods of traditional Chinese medicine do not belong to the scientific category. Why must modern science be applied to seek its scientific truth? If you really want to be reasonable, you should look for it in eastern philosophy, not in western science.
