Can medicines and foods from the same origin be sold with patent certificates?

Of course. Patent certificate is the symbol that the patentee owns the patent right, and the power of the patent right includes use, income, transfer, license, etc. When the inventor is the patentee, the inventor can use and buy and sell the patent right, so the homology of medicine and food can be sold with the patent certificate. The homology of medicine and food means that there is no absolute dividing line between many foods, that is, drugs. Ancient doctors applied the theory of "four natures" and "five flavors" of traditional Chinese medicine to food, and thought that every food also had "four natures" and "five flavors".
