Research shows that astragalus stimulates the immune system in several ways. It increases the number of stem cells in bone marrow, and encourages their maturity into active white blood cells. It appears to help signal the white blood cells known as neutrophils to migrate to places they are needed to fight infection. It stimulates the "germ-eating" white blood cells known as macrophages, activates T-cells & natural killer (NIK) cells, & increases the production of immune globulins
