Can astragalus be eaten often?

Tanida dream (oriental nutrition, natural good things) answer:

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 sweating due to hypoimmunity, 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, and it has synergistic effect when combined with interleukin -2(IL-2). Raw astragalus can also promote virus-induced interferon.

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

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

5. Raw Astragalus membranaceus has positive and negative two-way regulation on blood pressure. Through experimental observation, it is found that raw astragalus 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. Astragaloside IV can significantly prolong the time of thrombosis induced by electrical stimulation of common carotid artery in rats, inhibit platelet aggregation, increase the levels of prostacyclin (PGI2) and nitric oxide (NO), and decrease the ratio of thromboxane A2 (TXA 2) to prostacyclin (PGI2). It shows that TSA has significant antithrombotic effect, and its mechanism is related to increasing PGI: and NO levels.

7. Astragalus membranaceus can relax 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 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 can directly inhibit and kill viruses, and can also indirectly play an antiviral role by interferon or enhancing NK cell activity.
