The taste of traditional Chinese medicine exists in the pot for a period of time. It may be that you put the pot in the pot or other sealed space after using it, which leads to the strong smell of Chinese medicine in that pot. All you have to do is take that pot out and boil a pot of water, then pour out the water, and then open the pot for airing, so it won't affect the next pot of Chinese medicine. If it is ceramic pot, it will absorb some herbs. It doesn't really matter. My traditional Chinese medicine bowl has been boiled for dozens of times with different herbs, so it will not be affected by the smell of herbs. Don't worry. Moreover, the interaction between drugs is mainly the composition of drugs, not the smell.
