The molecular network of Guizhi, Shaoyao, Zhimu and GSZ. The molecular networks of Guizhi, Shaoyao, Zhimu, which are merged, are shown, as is the molecular network of GSZ. The target proteins are identified in the networks: yellow for Guizhi, red for Shaoyao, green for Zhimu, and purple for those shared by two or more proteins (details are listed in Supplementary Table 1).
