In clinical treatment, both Western and Chinese medicine practitioners prefer to use proprietary Chinese medicines, which are increasingly favored by doctors and patients because of their undervalued efficacy and convenience of use. However, in clinical use, it should also be based on the patient’s condition, looking, smelling, asking, and cutting, and the eight levels of identification, with the right evidence, with the right medicine, rather than one flavor can be used. Specifically, we should first identify the disease, then identify the evidence, and prescribe the right medicine. For example, Liu Wei Di Huang Wan is a classical formula and widely used in clinical practice. In dermatology, it is often used to treat chloasma, which is classified by Chinese medicine as kidney-yin deficiency, liver-depression and qi-blood disharmony. However, for doctors from Western medicine, it is difficult to differentiate and treat the symptoms, and Chinese medicine sometimes often ignores this aspect. Chinese medicine is sometimes ineffective because of its slow efficacy, and Chinese medicine says: pills are slow, and soups are swelling. As long as the dialectic evidence is correct, it should be used consistently, and the efficacy is certain.
