How to apply proprietary Chinese medicines? Medicine is a powerful weapon for human beings to fight against diseases, and Chinese medicine with a long history is an important part of it, which has played an indelible role in the development of the Chinese nation for more than 5,000 years. In recent years, due to the improvement of people’s living standard and the enhancement of self-care consciousness, coupled with the fact that Chinese medicines originated from nature have the advantage of having fewer side effects compared with chemically synthesized western medicines, it has made pCms more and more popular in prolonging life in addition to preventing and curing diseases. It plays an important role in protecting people’s health. At the same time, the irrational use of Chinese medicines (mainly pCms) and the abuse of tonic medicines have become more and more serious in recent years; the number of reports on adverse reactions to pCms has also increased. Application Principles of Proprietary Chinese Medicines Under the guidance of the theory of traditional Chinese medicine, medicines made of Chinese medicine tablets as raw materials, mass-produced according to prescribed prescriptions and standards, with specific names and labeled with their functions, dosages and specifications, are proprietary Chinese medicines. It is another embodiment of the application of Chinese medicine compounding, the essence of Chinese medicine prescription, reflecting the principle of Chinese medicine prescription and the efficacy of the proper combination of ruler, minister, adjuvant and enabler. The theory of Chinese medicine is the scientific basis for the application of pCms. It is reported that at present 60% of the domestic pCms prescription is issued by Western physicians, some Western physicians use pCms only know the disease of Western medicine and do not know the Chinese medicine of the “evidence”, or the application of pCms with Western medicine theory, which will inevitably affect the efficacy of pCms, and even undesirable side effects. For example, in the treatment of colds, according to the theory of Western medicine, colds are caused by cold viruses, patients can take oral antiviral particles (note: according to Chinese medicine theory, the drug is applicable to wind-heat colds); some Western physicians simply think that winter colds are wind-cold, summer colds are wind-heat. Chinese medicine practitioners believe that due to the differences in yin and yang, qi and blood of each person, and the feeling of different diseases, colds are usually divided into wind-cold colds (the treatment is pungent and warm to relieve the epidermis), wind-heat colds (the treatment is pungent and cool to relieve the epidermis), summer-dampness colds (the treatment is to clear the summer heat and dispel dampness to relieve the epidermis), qi-deficiency colds (the treatment is to benefit the qi to relieve the epidermis), and yin-deficiency colds (the treatment is to nourish the yin to relieve the epidermis), and the corresponding prescriptions and medications should be chosen according to the specific conditions of each person. The treatment should be based on the specific conditions of each individual, and the appropriate prescription should be used to treat the “evidence”. Western medicine and Chinese medicine are built on different foundations, and there are certain differences in their theoretical systems and modes of thinking. The application of Chinese medicine should naturally be guided by the theory of Chinese medicine to recognize the evidence, in order to achieve good therapeutic effect on the basis of safety.
