It has a synergistic effect with the central nervous system depressant sodium pentobarbital and can prolong the sleep time of mice; it has an antagonistic effect on the central nervous system stimulant pentobarbital; it reduces the mortality rate of mice caused by nicotine; it reduces the number of free activities of mice; and it increases the cerebral blood flow and coronary blood flow of dogs.

Astragalus polysaccharide improves the myocardial contractility of dogs with acute infarction, reduces the area of myocardial infarction, and alleviates myocardial damage; it has a certain improvement effect on microcirculation; it counteracts the immunosuppressive effect of cyclophosphamide or prednisolone; it activates human lymphocytes, mouse phagocytes and neutrophils, and enhances NK cell activity; it participates in the body's metabolism and promotes protein renewal; it has anti-tumor, cold-resistant, anti-hypoxia, anti-radiation, anti-fatigue and other stress effects; the anti-fatigue effect is produced by enhancing the function of the adrenal cortex.
