Why does Chinese medicine need frequent prescription changes?

The problem is very simple, but people who do not understand Chinese medicine do not know, so I want to tell more people, Chinese medicine conditioning is required to change the formula, in general, the causes of a disease is a variety of reasons, such as wind, cold, moisture, etc. in Chinese medicine. Generally we prescribe medicine for the main problem of the problem, and a small number of secondary problems to solve, so that the main contradiction can be solved quickly, the taste of medicine is less, the medicine is targeted, fast, while the extent of the disease is reduced, the main problem is solved, the other problems become the main problem contradictory problems need to change the prescription. So to summarize, because each time to solve the problem and the severity of the disease is different so need to change the prescription. I prefer to use precise medicine, to put it bluntly, the number of flavors of medicine is small, 9 to 12 flavors of medicine is best, if the patient is not able to short-term follow-up, the appropriate number of flavors of medicine can also be increased. With fewer drugs, there will be fewer chemical reactions in the boiling process, so that the main problem of the disease can be solved more specifically and more effectively, and there will be fewer side effects. If there are different doctors’ opinions, please express your own, because the TCM prescription itself is different from person to person, for a particular person’s specific prescription, not mass production.
