Network pharmacology analysis of GDFMD in the treatment of WD liver damage. Venn diagram (a); purple circles represent the gene targets of GDFMD, and yellow circles represent the gene targets of WD liver damage. PPI network based on STRING database (b); the more lines, the larger circle, and the brighter color represent the stronger correlation. Core genes in PPI network (c). TCM compound regulation network (d); light blue indicates intersection targets, leaf green indicates Lycium barbarum L., cyan indicates Panax notoginseng (Burkill) F.H.Chen, baby blue indicates Bupleurum chinense DC, yellow indicates Smilax glabra Roxb., purple indicates Curcuma aromatica Salisb., rose indicates Reynoutria multiflora (Thunb.), and red indicates Paeonia lactiflora Pall.
