Studies have shown that the use of Astragalus injection has a positive inotropic effect on the heart, enhances myocardial contractility, increases coronary blood flow, protects myocardial cells, and improves cardiovascular function.

Enhance the absorption and utilization of oxygen and glucose by tissue cells, improve the cellular hypoxia state and the internal environment of the body, increase the blood flow of organs such as the heart, brain, and liver, and improve microcirculation

It has anti-cerebral ischemia effect, improves brain edema in rats with multiple cerebral infarctions, promotes the glial cell reaction of brain softening foci, accelerates the absorption and organization of softening foci, reduces hippocampal neuronal lesions, protects gerbils from delayed neuronal damage in the hippocampus after transient cerebral ischemia, reduces the Ca2 content in brain tissue after ischemia, reduces the number of dead neurons, and increases neuronal density; it has anti-myocardial ischemia effect, reduces the symptoms of acute myocardial ischemia in rats, adjusts the downward shift of the S-T segment of the electrocardiogram, and improves the electrocardiographic inhomogeneity of patients with angina pectoris due to coronary heart disease; it improves blood rheology, reduces whole blood viscosity and plasma viscosity, and reduces It can reduce hematocrit and platelet aggregation rate, slow down erythrocyte sedimentation rate, and reduce fibrinogen content; improve microcirculation, reduce nail fold microcirculation morphological integral, flow integral, semi-circular integral, and overall integral, reduce peri-loop exudation, reduce tube diameter, increase flow velocity, reduce red blood cell aggregation, relieve congestion at the top of the loop, increase loop clarity, and eliminate edema; it has a lipid-lowering effect, reducing total cholesterol, triglycerides, and low-density lipoprotein levels; it has an effect of resisting free radical damage, increasing red blood cell superoxide dismutase activity, reducing plasma malondialdehyde content, and decreasing serum protein kinase C and aspartate aminotransferase levels.
