Astragalus is well-known for its immune-regulatory properties, particularly through its primary component, astragalus polysaccharide, which enhances the proliferation of T and B lymphocytes in tumor-bearing mice, promotes IL-2 production by spleen cells, and restores normal levels of IL-2, thereby improving cellular immune function and contributing to anti-tumor effects (24). Here, IL2 is linked to neoplasm.
