How difficult is it to apply for a patent for invention of traditional Chinese medicine?

Do you know the difference between the crime of producing and selling counterfeit drugs and the crime of producing and selling inferior drugs in the latest amendment 8 of the Criminal Law? It is a crime to produce and sell counterfeit drugs, which means that as long as you have this behavior, you will be convicted whether it causes harmful results or not. The crime of producing and selling inferior drugs is a consequential crime, and only when the behavior causes serious harm can it be convicted. There are so many remedies in traditional Chinese medicine that they can only be called remedies, but they cannot be patented as drugs protected by law. It is precisely because if the folk prescription is patented, it is a crime for those who produce or sell drugs made of folk prescription to be careless. Another point is that the state is very strict in the management of drugs. Only western medicine can enter the sales field after several years or decades of verification. The sales of drugs are also divided into prescription drugs and over-the-counter drugs, not to mention Chinese medicine. Traditional Chinese medicine has a long history, and many aspects of science cannot be explained clearly for the time being, so I would rather not approve it and not let it go.
