http://www.physorg.com/news100089123.html North Central Cancer Treatment Group researchers, based at Mayo Clinic in Rochester, Minn., have generated preliminary data suggesting that a form of American ginseng provides greater improvements in fatigue and vitality in patients who receive the highest doses tested, compared to lower doses or no treatment.
The results of their scientifically rigorous pilot study, the first to evaluate the Wisconsin species of American ginseng as a possible therapy for cancer-related fatigue, are being presented June 3 at the annual meeting of the American Society of Clinical Oncology.

Traditional Chinese medicine and current understanding of ginseng’s function both point to its characteristics as an adaptogen -- a substance that helps the body overcome the effects of environmental stress. Since cancer patients have stressors ranging from the psychological stress of diagnosis to the physiological stresses of chemotherapy and radiation, if ginseng helps, the researchers think it would be a valuable addition to currently available therapies.

Of the four treatment arms, patients receiving the placebo and the lowest dose of ginseng reported very little improvement in fatigue or other areas of physical or psychological well-being. The patients receiving the larger doses showed improvements in overall energy levels, reporting higher vitality levels and less interference with activity from fatigue. They also reported an improvement in overall mental, physical, spiritual and emotional well-being.
