Research Progress on Processing of Polygalae Radix / 中国实验方剂学杂志

ABSTRACT

Polygalae Radix， a traditional Chinese medicine， has the functions of improving intelligence， calming nerves， relieving cough and eliminating phlegm. Its processing methods are various， but the purpose of processing is to reduce toxicity and increase efficiency. In this paper， the methods of ancient processing， such as cleansing， cutting， processing with excipient and processing without excipient， were summarized， the processing methods of Polygalae Radix in the different versions of Chinese Pharmacopoeia and the local processing specifications were summarized， in order to compare the differences and research progress of different processing methods. On this basis， taking the modern research of processed products of Polygalae Radix as the breakthrough point， this paper reviewed the modern research on processed products of Polygalae Radix from the aspects of processing technology， chemical composition changes and pharmacodynamics changes before and after processing， and the mechanism of reducing toxicity and increasing efficiency. Based on the research status of processing of Polygalae Radix， some existing problems were analyzed in this paper， including not many ancient processing methods used in modern times， lack of standardized research on processing technology， few studies on the ingredients introduced by excipients， etc. The author thinks that it is necessary to strengthen the research on the ancient processing of Polygalae Radix combined with processing methods with local characteristics. While discussing the processing technology， combining with the composition and efficacy， we should carry out in-depth research on the processing mechanism of different processing products of Polygalae Radix， so as to provide scientific basis for the rationality of processing of Polygalae Radix and ensure the clinical safety of medication.
