PK of traditional Chinese medicine and western medicine (in fact, traditional medicine and modern medicine) has been going on, that is, scientific clinical trials. New therapies and drugs in modern medicine have to undergo rigorous scientific experiments, that is, "multi-center, large-sample randomized double-blind controlled human clinical trials". Through these experiments, we can draw data conclusions including curative effect (cure rate), side effects and adverse reactions. Traditional Chinese medicine therapy and drugs do not do scientific experiments, but only rely on imagination, reasoning, intuition and feeling to confirm the efficacy. There is no medical evidence of curative effect at all, and the ingredients, toxic side effects and adverse reactions are unclear, so patients can use it directly. Is it not clear which is higher or lower?
