Why is astragalus necessary for your body?

Astragalus contains cycloastragenol, a substance that may activate telomerase, which prevents the destruction of your telomeres. Since telomeres are markers on your DNA that cause you to age when they break down, astragalus may support healthy ageing.

This multi-talented, natural substance appears to improve your health whether you’re troubled by infectious disease or not.

Functions of astragalus

  • Potential immune benefits: Research indicates  that astragalus may increase your white blood cell count, and this substance may help with infections by directly targeting viruses and harmful bacteria. Astragalus may also help with hepatitis, a form of liver infection.
  • Potential anti-aging benefits: Studies show that the saponins in astragalus may extend the length of your shortest telomeres, preventing DNA destruction and subsequent cell death.
  • Potential cardiovascular benefits: Clinical research indicates that astragalus may improve overall cardiovascular function by widening your blood vessels. Limited research also indicates that this substance may be useful for preventing congestive heart failure.
  • Potential diabetes benefits: Clinical studies show that astragalus may help with the symptoms of type 2 diabetes by reducing blood sugar levels.
  • Potential kidney benefits: Research shows that astragalus may prevent proteinuria, a common indicator of poor kidney function. This substance may also prevent infections associated with kidney disease.
  • Potential fatigue benefits: In combination with other herbs used in traditional Chinese medicine, astragalus may reduce the symptoms of chronic fatigue.
