What Is Astragalus?

Astragalus is commonly known as milk vetch.

Astragalus is a large family of annual and perennial flowering herbs. It is also known as milk vetch and in China as huang qi (or huangqi). Although primarily native to China, some of the 2000 species of astragalus grow naturally in Europe. 1, 2

Biologically Active Compounds in Astragalus

In the west, extracts from astragalus have been used in industries for decades for non-medicinal purposes. Now modern research is beginning to support how astragalus is used in traditional herbal medicine. Studies show that many of the over 200 compounds in astragalus have useful properties, including antioxidant and anti-inflammatory effects. 1-4

These beneficial compounds include: 1, 2, 4-7

  • Amino acids (including arginine and GABA)
  • Astragalosides (immune regulating and anti-aging compounds, mainly from the roots)

Astragalus is also used in traditional Palestinian medicine. Of the 4 species of astragalus most frequently used in Palestinian folk medicine, Astragalus boeticus has the most potent antioxidant, antibacterial, and antifungal properties. 9

Species of Astragalus Used

The two species which have been tested the most for pharmacological significance are Astragalus membranaceus and Astragalus mongholicus. Recent studies suggest that other species of astragalus may also have beneficial properties, particularly in cardiovascular disease, protecting liver health, and treating psoriasis. 2, 10-13

Natural Life Extension?

Astragalus appears to have real anti-aging properties. In fact, one compound in the roots of A. membranaceus can actually increase the length of chromosome tips. Called telomeres, these segments of DNA help protect DNA, and telomere length is linked to lifespan. 4, 74, 75
