Now there is some evidence that ginseng’s claim to fight fatigue may be deserved. In a small number of independent studies, researchers have found that ginseng extracts seem to help combat cancer-related fatigue, one of the most common side effects of chemotherapy and other treatments. The fatigue can be so severe that patients often call it paralyzing, and there are few options for alleviating it. In a randomized double-blind study with 290 cancer patients at the Mayo Clinic in 2010, more than twice as many patients taking 1,000 or 2,000 milligrams of ginseng a day reported less fatigue and more energy after eight weeks compared with those given a placebo.
