Ginseng for Immune Enhancement

Many studies show that ginseng revs up the immune system. Scientists at the University of Milan. Italy, gave ginseng (100 mg a day) or a placebo to 227 people. A month later. everyone received a flu shot (which does not kill the flu virus. but rather stimulates the immune system to resist infection). In the placebo group, 42 people got the flu, but in the ginseng group, the figure was just 15, demonstrating that ginseng enhanced immune response to the shot.
