Why didn't the ancient prescription of traditional Chinese medicine go through the procedure of "drug testing" in clinical experiments?

The Law of Traditional Chinese Medicine, which came into effect on July 20 17, has clearly stipulated: "When applying for the drug approval number, only non-clinical safety research data can be provided for the production of traditional Chinese medicine compound preparations that meet the requirements of the state." In other words, the "ancient prescription of traditional Chinese medicine" does not have to go through the "drug test" procedure of clinical experiments. At present, Chinese medicine has experienced two large-scale "drug tests", and the results are quite embarrassing.

First, the debate of the First Pharmacological Society: there are few positive results.

196 1 year, "the first academic seminar of pharmacology major of China physiological science society" was held in Beijing. The theme of this conference is "looking for new drugs". Pharmacological experiment screening of traditional Chinese medicine is an important part of traditional Chinese medicine research. Participants reviewed the results of the national Chinese medicine "experiment" since 1958: "Since liberation, many achievements have been made in Chinese medicine research. However, due to lack of experience, the work is not going smoothly, with many negative results and few positive results. Many (claimed) prescriptions with effective clinical reports have not been confirmed in animal experiments. "

"Most of the screening work of traditional Chinese medicine done by our unit is negative (author's note: it can't prove effective), and a few are positive." "It is difficult to draw a definite conclusion by observing the brittleness of blood vessels and the time of blood coagulation to study Chinese medicine for hemostasis. ..... In addition, the blood-enriching prescriptions commonly used in Chinese medicine can't give positive results if they are tested by modern methods, such as bone marrow examination and blood test. " (1) This conclusion undoubtedly embarrassed the Chinese medicine practitioners who attended the meeting at that time. At the meeting, they concentrated on criticizing that the "drug testing" method of modern medicine is not suitable for Chinese medicine: "Some are methodological, some are because they don't study Chinese medicine enough, and some are not serious enough in scientific work, so many drug experiments get negative results." "In the past, important screening work was not diversified enough, so most of them were negative results." "Many theories of traditional Chinese medicine are difficult for western medicine to understand ... Some current experimental methods are difficult to reflect the real pharmacological effects of traditional Chinese medicine." ②
