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.


What is the functions of Astragalus root extract?  

1.Studies have documented that Astragalus boosts activity of several kinds of white blood cells and increases production of antibodies and interferon, the body own natural anti-viral agent.                                                   

2.Improve immunity.
3.It is a first class herb for maintaining a healthy immune system.
4.As an immune system tonic, Astragalus It helps the body to fight off external pathogens that you may come  in contact with.                                     

5.It thus directly supports the Lung and Spleen organs in the body. By supporting those organs, energy derived from the foods and the air is increased.
6.Cardial activity on exhausted heart, Hypotensive activity, Diuretic activity, Sedative effect, Immunity enhancer.                                            

 How about the applications of Astragalus root extract? 

1. Pharmaceutical stuff.

2. Functional food and food additive.

3. Livestock products and poultry products.

4. Water-soluble beverages.  

5. In heart cerebrovascular aspect,it can inhibit platelet aggregation, reduce blood viscosity and coagulation, relax smooth muscle, expand of cerebrovascular, reduce vascular resistance, improve blood circulation, especially improve the microcirculation, can also inhibit the formation of arterialthrombosis.
