A weakened immune system and
fatigue are commonly encountered when one is on a low-calorie diet or in the
midst of changing diets. American ginseng is a rich store of nutrients for
revitalizing the body.
A Tonic for the Immune System
American ginseng helps to strengthen the immune system in a variety of
ways. Its polysaccharides help balance the immune system and enable it to
destroy existing cancer cells and viruses. Scientists reported that these
polysaccharides may stimulate macrophages (multi-tasking immune cells) to
secrete cytokines, chemicals that summon immune cells to deal with bacteria
and viruses. American ginseng also builds up immunity by stimulating the
production of tumor necrosis factor α (TNF- α ), an immune
chemical used in fighting viruses.
American ginseng's immunity-building abilities have been demonstrated by
its extract, which is rich in poly-furanosyl-pyranosyl-saccharide. A study
revealed that consuming a moderate dose over four months may reduce the
number of colds, the severity of colds and the number of days they last,
possibly preventing respiratory tract infections.
Nutritional Immunology research
shows that American ginseng helps the body adapt to fatigue, stressful
conditions and changing temperatures.
American ginseng can energize when the body experiences tiredness, and
tranquilize when the body is under stress. By regulating the body's
production of stress hormones and protecting the hippocampus from the
effects of stress hormones, the substances n American ginseng reduce stress
reactions greatly. Ginsenosides such as Rb1 can help the body to cope with
stress and increase rates of learning.
American ginseng is also packed with fiber, iron, magnesium, potassium,
zinc, vitamin C, and B-vitamins.
