Astragalus is generally divided into two types: raw astragalus and roasted yellow.

When the prescription medication is not specified, it generally refers to Astragalus membranaceus.

Effect 1. Enhance immune function. Astragalus can enhance the phagocytosis function of the reticuloendothelial system, significantly increase the number of blood leukocytes and multinucleated leukocytes, significantly increase the phagocytosis percentage and phagocytosis index of macrophages, and have a significant impact on body fluids. Both immunity and cellular immunity can be promoted.

After normal people take it, plasma IgM and IgE will increase significantly, and the whole plant has the best effect.

Astragalus can promote the formation of serum hemolysin, improve the hemolytic ability of plaque-forming cells, and has an obvious effect of clearing carbon particles and increasing spleen weight.

The above effects exist under normal physiological conditions and also have obvious effects when the immune function is low.

Astragalus not only has an enhancing effect on low immune function, but also has a two-way regulatory effect.

The active ingredient F3 of Astragalus has been shown in in vitro tests to have a complete recovery effect on lymphocyte function in cancer patients, and in vivo animal model tests have been shown to completely reverse the immunosuppression caused by cyclophosphamide, suggesting that Astragalus components may be a promising biological response modifier in immunotherapy.

Astragalus can increase the activity of natural killer cells (LAK) activated by lymphokine (interleukin-2).

2. Effect on interferon Astragalus has the ability to enhance the ability of viruses to induce interferon.

People who are prone to colds take astragalus during the cold season, which can not only significantly reduce the number of colds, but also make cold symptoms milder and the course of the disease shorter.

3. Enhance the body’s ability to withstand hypoxia and stress. Astragalus polysaccharide has an obvious anti-fatigue effect, and can significantly extend the swimming time and increase the weight of epinephrine in hydrocortisone-depleted mice. Various hypoxia models have significant tolerance capabilities, which can significantly reduce systemic oxygen consumption and increase tissue hypoxia tolerance.

Astragalus polysaccharide has obvious low temperature resistance and can significantly extend the survival time of normal and depleted mice.

4. Promote body metabolism. Astragalus can enhance the physiological metabolism of cells, which may be accomplished through the regulation of intracellular cAMP and cGMP.

Astragalus can also promote protein renewal in serum and liver, and promote protein metabolism. This may be another important aspect of astragalus's righting effect.

5. Improve heart function. Astragalus has the effect of strengthening the contraction of the normal heart. For the heart that has failed due to poisoning or fatigue, the cardiotonic effect is more significant, which can increase the amplitude of cardiac contraction and expel excretion. Increased blood volume.

100% Astragalus injection can strengthen and accelerate the contraction of isolated hearts.

Astragalus can improve left ventricular function in patients with viral myocarditis, and also has certain anti-arrhythmic effects, which may be caused by prolonging the effective refractory period.

6. Antihypertensive effect: Subcutaneous or intravenous injection of astragalus decoction, water infusion, and alcohol infusion into anesthetized animals (dogs, cats, rabbits) can lower blood pressure, and the effect is rapid and sustained. Time is short.

The antihypertensive effect is the result of direct dilation of peripheral blood vessels.

Injecting Astragalus injection into the coronary arteries, vertebral arteries, superior mesenteric arteries, cerebral blood vessels, intestinal blood vessels and other visceral blood vessels of experimental dogs can reduce the vascular resistance index, but when injected into the renal arteries, the renal vascular resistance index On the contrary, it increased, indicating that the effect of astragalus on renal blood vessels is different from that on blood vessels in other parts of the body.

7. Hepatoprotective effect Astragalus can prevent the reduction of liver glycogen and has a protective effect on carbon tetrachloride hepatitis in mice.

Astragalus also has a certain effect on the conversion of hepatitis B virus surface antigen from positive to negative. Compared with the control group, the difference was significant (P<0.05).

The clinical effectiveness in treating chronic hepatitis was 92.1% for liver stagnation and spleen deficiency type and 88.5% for liver and kidney yin deficiency type, both of which were better than those of the control group (P0.05), indicating that the use of astragalus alone The efficacy in treating chronic hepatitis is not ideal.

8. Regulate blood sugar. Astragalus polysaccharide has the effect of regulating blood sugar in both directions. It can significantly reduce the blood sugar level of mice after glucose load, and can significantly resist the increase in blood sugar level of mice caused by epinephrine. It has no significant effect on insulin hypoglycemia.

Ask about health 9. Anti-bacterial and virus-inhibiting effects. Astragalus has inhibitory effects on Shigella dysentery, Diplococcus pneumonia, hemolytic Streptococcus A, B, C and golden, lemon and white Staphylococcus aureus. effect.

Astragalus also has a certain inhibitory effect on the pathogenic effects of oral viruses and influenza Sendai BB1 virus, but has no direct inactivating effect.

10. Hormone-like effects Astragalus has similar hormone-like effects, which can prolong the estrous period of mice and have a good impact on the development of mice.

11. Others Astragalus can significantly reduce the blood rheology index of rabbits, and its properties and strength are the same as those of Salvia miltiorrhiza injection.

100% Astragalus injection has exciting and contractile effects on the isolated uterus of rats.

Astragalus injection can promote the growth of chicken embryo femur in vitro.

Astragalus also has the effect of promoting the increase of hemoglobin, serum protein and albumin in patients with aplastic anemia.
