What is Astragalus?

Astragalus is an herb from traditional Chinese medicine (TCM) which is traditionally used for its immune enhancing properties, but is also recommended in TCM for "deficiency of chi" (life force) ¨C which might include symptoms such as lack of energy and fatigue. The plant is native to Northern China and Mongolia and there are over 2,000 types of astragalus worldwide.

The natural gum tragacanth is made from several species of  Astragalus  occurring in the Middle East, including  A. adscendens ,  A. gummifer ,  A. brachycalyx , and  A. tragacanthus . Also  Astragalus propinquus  (also known as  Astragalus membranaceus ) has a history of use as a Herbal medicine and is used in traditional Chinese medicine.

What is Astragalus Extract Cycloastragenol ?

 In October 2010, Intertek/AAC Labs, an ISO 17025 internationally recognized lab, found the largest component of TA-65 to be Cycloastragenol.  Cycloastragenol is a sapogenin found in or derived from Astragalus membranaceus.  It seems to moderately increase telomerase activity and proliferative capacity in both CD4 and CD8 T cells in  in vitro experiments. Cycloastragenol is extracted and purified from the roots of Astragalus membranaceus, being claimed to stimulate immune system, to improve cardiovascular health, and to repair DNA.

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.
