There are about 5,000 kinds of traditional Chinese medicine preparations in my country and more than 4,000 kinds of western medicine preparations. It can be seen that the types of drugs are complex and varied.
2. Medical exclusivity of medicine: medicine is not an independent commodity, it is closely integrated with medicine and complements each other. Patients can only achieve the purpose of preventing disease and protecting their health if they pass the examination and diagnosis of a doctor, and use the medicine rationally under the guidance of doctors and licensed pharmacists.
