These forms of treatment typically ravage the body's immune system and leave patients weak and susceptible to new opportunistic infections. Scientists have isolated a number of active ingredients contained in Astragalus, including bioflavonoids, choline, and a polysaccharide called 'Astragalan B'. Animal studies have shown that 'Astragalan B' is effective at controlling bacterial infections, stimulating the immune system, and protecting the body against a number of toxins. Astragalan B seems to work by binding to cholesterol on the outer membranes of viruses, destabilizing their defenses, and allowing for the body's immune system to attack the weakened invader. Astragalus also increases interferon production and enhances NK and T cell function, increasing resistance to viral conditions such as hepatitis, AIDS and cancer.
Astragalus shows support for peripheral vascular diseases and peripheral circulation.
It produces gradual beneficial changes within the body by improving general nutrition and by gradually altering the health of the blood. Burdock has also been shown to enhance liver and bile functions. Bacteriostatic principles have been isolated from Burdock root, and it has been found to inhibit tumor growth. Documented effects include treatment of scurvy, venereal eruptions, leprosy, and other cankerous skin conditions. The Indians obtained more mileage from this single herb than practically any other medication.
