Objective: To identify the Yi medicine pediatric abdominal pain grass. Methods: Using traits identification, microscopic identification, physical and chemical identification methods. Results: The stratum and phloem of root and stem cross sections had stone cells and the stem vascular bundle was double-toughened. The powder contained a large amount of stone cells and fibers. The upper and lower epidermis both had stomata and stomatal inequality. Pollen grains were spherical, With three germination holes; TLC, the test samples in the position corresponding to the reference substance chromatography, was the same color fluorescent spots, with good reproducibility. Conclusion: The above characteristics can be used as a basis for the identification of pediatric abdominal pain.
