title: [Suggestions for improving quality control of extrinsic residues in crude drugs].
abstract: To improve the impurity control of extrinsic residues in Chinese crude drugs and ensure the quality of crude drugs, relative suggestions should be provided. The present situation of extrinsic residues control in crude drugs was reviewed, and relative problems existed were analyzed. To develop the impurity control of extrinsic residues in Chinese crude drugs, more effort focus on strengthening basic research, improving analytical methods and optimizing the pattern of administration should be made.
