In short, the authenticity and superiority and inferiority of medicinal materials are directly related to the safety and effectiveness of clinical drug use. The authenticity refers to its quality, and the pros and cons indicate its quantity. However, there is no strict boundary between the two, and quantitative change can cause qualitative change. Such as licorice, when the content of its active ingredient is low to a certain extent, it loses its efficacy. Although it is also called licorice, it has no use value.
Therefore, blindly using genuine medicinal materials not only requires that the primordial origin is correct, but also its characteristics and microscopic features are correct. It must have the content of a chemically effective substance that meets the regulations or the relative content of a series of ingredients, and it must meet the requirements for the inspection of various items. It is true that many herbs do not have a clear active ingredient or indicator ingredient, and they have no labeled content. Their authenticity and merits only depend on the identification of experience. Identification of Chinese medicine, there are very arduous tasks waiting for us.
