The main components of raw astragalus are astragalus polysaccharides, saponins, flavonoids, vitamins and trace elements, among which astragalus polysaccharides, saponins and flavonoids are effective components with various pharmacological effects.

1 Raw Astragalus membranaceus is the most basic Chinese medicine used to improve the immunity of lung and respiratory system. It can be used for asthenia caused by low immunity, and can also be used for invigorating qi and improving spleen function and metabolism.

2. Raw Astragalus membranaceus can obviously increase the total number of white blood cells in blood and promote the phagocytosis and sterilization of neutrophils and macrophages. The decoction of raw astragalus can obviously enhance the activity of natural killer cells (NK cells); Astragalus polysaccharide (APS) can stimulate the proliferation of NK cells and make their cell bodies bigger, which has a synergistic effect when combined with interleukin -2(IL-2). Raw astragalus can also promote virus-induced interferon.

3. Raw Astragalus membranaceus can enhance the function of dendritic cells. When dendritic cells sensitized by tumor antigen peptides are used to treat tumors, combined application of raw Astragalus membranaceus injection can more effectively induce tumor-bearing hosts to produce tumor antigen-specific cytotoxic T cells (cTL).

4. Astragalus membranaceus can promote bone marrow hematopoiesis, promote the generation, development and maturation of various blood cells, and restore the low red blood cell (RBC) and white blood cell (WBC) counts of mice to normal levels.

5. Raw Astragalus membranaceus has a positive and negative two-way regulating effect on blood pressure. Through experimental observation, it is found that raw Astragalus membranaceus can dilate peripheral vascular resistance, reduce arterial pressure and right ventricular preload, and improve cardiac function. The main antihypertensive component is γ -aminobutyric acid (GA-BA).

6. Raw Astragaloside (TSA) can significantly prolong the time of thrombosis caused by electrical stimulation of common carotid artery in rats, inhibit platelet aggregation, increase the levels of prostacyclin (PGI2) and nitric oxide (NO), and reduce the ratio of thromboxane A2(TXA2)/ prostacyclin (PGI2). It shows that TSA has significant antithrombotic effect, and its mechanism is related to increasing PGI: and NO levels.

7. Radix Astragali has relaxing effect on vascular smooth muscle, and its mechanism may be related to blocking the opening of inositol triphosphate-sensitive calcium channels on endoplasmic reticulum of vascular smooth muscle cells and inhibiting the release of internal calcium.

8. Raw Astragalus can also promote metabolism, reduce aldose reductase activity and reduce sorbitol accumulation.

9. Alkaloids, flavonoids and glycosides contained in raw Astragalus membranaceus can directly inhibit and kill viruses, and can also indirectly play an antiviral role through interferon or enhancing NK cell activity.
