Mayo Clinic researchers report that a type of American ginseng (Panax quinquefolius) appears to aid patients with cancer-related fatigue. Researchers enrolled 282 patients in an eight-week trial of either placebo or three different daily doses of ginseng: 750, 1,000 and 2,000 mg. Those receiving the placebo and the lowest dose of ginseng reported very little improvement, while 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.
