Microscopic identification Cross-section of rhizomatous stems of Hu Huanglian in Tibet: 1 row of cells in the epidermis, often absent from the epidermis of rougher rhizomes. The cork layer is a series or more than ten cork cells. Cortical parenchymal cell wall is slightly thicker, some with large round single-orifice or reticulate pits, intracellular cavity containing fatty oil droplets; the endothelial cell is rectangular. The plenum is 2-3 rows of parenchyma cells. Phloem parenchyma cells contain starch grains, fatty oil droplets, and resin blocks. The formation of layers between the bundles is not obvious. The xylem consists of a tube, a wooden parenchyma, and a wooden beam, which is woody. The primary ray is 9 rows wide. The pith is a round-like parenchyma with obvious cell gaps, and some cell walls have round single- and single-spotted holes.
