The role of Cycloastragenol in immune system

The role of Cycloastragenol in immune system
All normal human somatic cells have a finite number of times that they can divide and when this limit is reached cells are described as cellular senescent. . There are various nutraceuticals that claim to both increase the health of individuals and delay the onset of cellular aging. Cycloastragenol is extracted and purified from the roots of Astragalus membranaceus, being claimed to stimulate immune system, to improve cardiovascular health, to repair DNA, and to activate telomerase that is crucial for anti-aging. As Cycloastragenol for their ability to enhance T cell functions in vitro, cycloastragenol moderately increase telomerase activity and proliferative capacity of both CD4 and CD8 T cells.
