Astragalus is a large genus of about 3,000 species of herbs and small shrubs, belonging to the legume family Fabaceae and the subfamily Faboideae. It is the largest genus of plants in terms of described species.The genus is native to temperate regions of the Northern Hemisphere.
Cycloastragenol has a similar chemical structure to that of the Astragaloside IV molecule, but it is smaller and significantly more bioavailable, enabling lower doses to be taken. It is already used as an immunostimulant because of its ability to increase T lymphocyte proliferation. However, it is its exceptional anti-aging properties that are of increasing interest to the scientific community. Cycloastragenol stimulates the repair of DNA damage by activating telomerase, a nucleoprotein enzyme which catalyses synthesis and growth of telomeric DNA. Telomeres are made of thin filaments and are found at the tips of chromosomes.
Maintaining their stability enables cells to avoid replicative senescence and indefinite proliferation beyond the ‘Hayflick limit'. Telomeres shorten with each cycle of cell division, or when subjected to oxidative stress. Until now, this has been an unavoidable mechanism of aging
