Objective: To reveal the classification and the sources of impurities in crude drugs and yinpian (herbal pieces prepared for decoction) to improve their quality. Methods:The impurities were classified and the ways they mixed with the drugs were discussed based on our experience. Results: There was a variety of impurities in crude drugs and yinpian, which could be classified into 3 types. The impurities mixed with the crude drugs when the drugs were planted, bred, processed and circulated. Conclusion:The mix of the impurities is caused by the natural and the artificial factors, and the latter is the principal one. The source of the impurities must be controlled. State Drug Administration should take part in the whole course of the yinpian production and circulation, and the users should pay attention to the commodity inspection in order to put an end to the adulteration.
