High-throughput screening revealed PC as a metabolic regulatory agent. A Heat map of the gene expression profiles of 81 TCMs, together with Rhizoma Coptidis and berberine. Red represents the upregulated genes; blue shows the downregulated genes. B Correlation coefficient matrix of PC, C. chinensis, C. deltoidea and C. teeta, the color in the heat map represents the correlation coefficient between each two groups of samples, and the color ranges from white (low correlation coefficient) to red (high correlation coefficient). C Scatter plots between PC and C. chinensis from Shizhu; R2 = 0.71. Each spot represents a differentially expressed gene
