Astragalus does not have a definitive cure for premature beats. The main chemical components of Astragalus are triterpenoid saponin components, and certain flavonoid components, including polysaccharides and amino acids. Pharmacological research now confirms that astragalus polysaccharides can promote RNA and protein synthesis, enable vigorous cell growth and life extension, and can be anti-fatigue, low-temperature resistant, and anti-influenza virus. Astragalus decoction, polysaccharides and saponins have protective and promotional effects on hematopoietic function, and total saponins of Astragalus have positive muscle effects. Astragalus total flavonoids and total saponins can protect ischemic and hypoxic myocardium, astragalus decoction has kidney protection, elimination of proteinuria and diuretic effect, and bidirectional regulation of blood pressure. In addition, Astragalus can also be anti-aging, anti-radiation, anti-inflammatory, hypolipidemic, hypoglycemic, enhance immunity as well as hepatoprotective effects.
