目的:提供一种既简单又方便的方法,来区分中药饮片芦根及其混淆品菰根,以确保两药的临床用药安全。方法:分别采集芦根和菰根两者的药材标本,进行性状和显微构造观察,对两者进行比较分析。结果:芦根及菰根在表面颜色、断面、内表面、气味等性状及横切面显微和粉末显微等方面都具有差异。结论:芦根及菰根在药材性状和显微构造等方面的特征,补充和完善了两者的鉴定指标,从而避免两者的混用、误用、代用,确保临床用药正确、安全、有效,同时也能够为其深入研究和临床用药提供理论依据。 OBJECTIVES: To provide a simple and convenient method for distinguishing between Rhizoma Imperatae and its confused product Rhizoma Dioscoreae, to ensure the safety of the two drugs. Methods: The medicinal materials of both rhizome and root of Radix Rehmanniae were collected, and their traits and microstructure were observed. The two were compared. Results: The reed rhizome and rhizome root showed differences in the surface color, cross section, inner surface, odor and other aspects as well as the cross section and microstructure. Conclusion: The characteristics of reed rhizome and rhizome root in medicinal properties and microstructure are complemented and perfected, so as to avoid the misclassification and misuse of the two, so as to ensure the correctness, safety and effectiveness of the clinical medication, At the same time, it can provide theoretical basis for its further research and clinical medication.
