ABSTRACT
The National Medical Products Administration intends to simplify the registration and approval process of the classic Chinese herbal compound preparations that meet the requirements, but it is a prerequisite for obtaining preferential policies that the preparation method and the route of administration are consistent with the records of ancient medical books. As most of the famous classical formulas are recorded in the medical books of the Qing dynasty and before the Qing dynasty, during the use of medicinal materials in various dynasties, the processing of herbs, dose of medicinal herbs, and the method of decocting may have changed. If researchers simply adopt modern methods to study the formula, it is easy to deviate from policy requirements. The strengthening of preliminary data survey and definition of prescription component and the medication situation of the dynasties can provide strong theoretical support for the study of famous classical formulas. Based on this, the authors take Xiebaisan as an example, which being collected in the First Batch of Catalogue of Ancient Classical Formulas. By following the principles of ancient methods, the research and development ideas of the classic Chinese herbal compound preparations were expounded from the aspects of origin of medicinal materials, processing of medicinal materials, preparation of standard decoction and quality standard of Xiebaisan granules, so as to provide a referential method for the development and research of the famous classical formulas.
