Discussion on Classification of Chinese Crude Drugs Processing Methods in “General Principles for Processing” of Chinese Pharmacopoeia

OBJECTIVE To explore the national universal classification of processing methods for Chinese crude drugs. METHODS Making recommendations for improving the classification of processing methods for Chinese crude drugs in the General Principles for Processing of Chinese Pharmacopoeia by reviewing and analyzing the traditional processing methods documents, the Chinese Pharmacopoeia 2015 Edition, and the processing standards of Chinese crude drugs of various provinces. RESULTS & CONCLUSION Based on the processing technology, the classification of processing methods for Chinese crude drugs should pay equal attention to both the processing methods in literature and the practical needs in the current Chinese crude drugs production. The processing methods in the General Principles for Processing were classified into six categories:cleaning, cutting, stir-frying, calcining, steaming and boiling and others, which not only reflects the commonality of Chinese crude drugs production, but also takes into account regional characteristics. By establishing the General Principles for Processing applicable to all Chinese crude drugs production, manufacturers will obtain adequate autonomy and regain vitality, which will promote the distribution and use of Chinese crude drugs nationwide.
