First, you have to apply for a patent. If you can, you should do experiments, biological experiments, clinical experiments, and finally human experiments. If it is only a prescription, it is estimated that no pharmaceutical company dares to ask for it. If someone casually took a prescription and said that my prescription could cure many diseases, would you believe it? So you still need to do a lot here and put in a lot. The best way is to apply for a national patent and find a professional to write a feasibility report.
Of course, there are still many procedures that I can't remember clearly.
