OBJECTIVE： To provide reference for standardizing the names and definitions for the processing methods of “general principles for processing” in reprinted Chinese Pharmacopoeia. METHODS： Comparing with the Processing of Chinese Materia， Beijing Processing Specification for TCM Decoction Pieces， Shennong Bencaojing and National Processing Specification for Chinese Herbal Medicine， parts of the name and definition problems for processing methods of “general principles for processing” in Chinese Pharmacopoeia （2015 edition， Vol Ⅳ） were analyzed， and suggestions were put forward. RESULTS： The definitions of partial items in the “general principles for processing” in Chinese Pharmacopoeia remained to be normalized and operability remained to be improved. For example， the definitions of stir-frying， stir-frying with wine， stir-frying with vinegar， stir-frying with salt and stir-frying with honey were not accurate， so as the steaming. The name of the processing method under the term of decoction pieces was not identified， there was deviation in the scope of crystallizing definition， and amount of pharmaceutic adjuvant was not worthy to be generalized. CONCLUSIONS： When generalizing and defining the processing methods for all TCM decoction pieces， Chinese Pharmacopoeia should give consideration to the popularity， accuracy and universality.
