Study has shown that dandelion polysaccharides can alleviate CCL4-induced pulmonary fibrosis in rats, and mitigate inflammatory responses and oxidative stress injury by scavenging free radicals and attenuating inflammatory cell activation [75]; Li et al. [76] used nimodipine as a positive control group and found that Panax notoginseng polysaccharides improved the antioxidant capacity of brain tissues and inhibited overproduction of inflammatory cytokines, and had a protective effect on rat I/R injury with protective effects. This evidence concerns the gene CCL4 and pulmonary fibrosis.
