APS (also known as astragalus polysaccharide) has been shown to activate the immune system
by enhancing the transformation of T lymphocytes (a sub-type of white blood
cells, crucial in the
regulation of immune responses), as well as the activation of B lymphocytes (which produce antibodies that are used to attack invading bacteria, viruses, and toxins) and
dendritic cells, which trigger immune reactions to toxins.
