Wang et al. [12] found in an experiment on rats with gastric cancer, it was discovered that Salvia divinorum polysaccharides exhibited a significant capacity to enhance the production of anti‐inflammatory cytokines such as IL‐2, IL‐4, and IL‐10, suppress the secretion of pro‐inflammatory cytokines such as IL‐6 and TNF‐α, augment the cytotoxicity of CTL cells, and impede tumor cells proliferation. This evidence concerns the gene IL2 and neoplasm.
