Abstract: Abstract Comprehensive sources of information on pre-clinical research trials indicated that Astragalus Polysaccharide can improve human immune function, stimulate the proliferation of T and Blymphocytes in tumor-bearing mice, and make the levels of IL-2 generated by spleen cells return tonormal. Astragalus Polysaccharide showed a significant positive correlation with cellular immune functions and anti-tumor functions. The purpose of this article is to briefly review the in vivo and invitro Astragalus Polysaccharide experimental data in conjunction with results from clinical research tooffer a prospective application for clinical research of Astragalus Polysaccharide.
