Gingseng and Fatigue

American ginseng does not improve fatigue in multiple sclerosis: a randomized double-blind placebo-controlled crossover study.

This study examined the safety and efficacy of an escalating dose (100 mg, 200 mg, 400 mg/day) of American ginseng over 6 weeks in 56 MSers with fatigue. There were no serious adverse events but fatigue on ginsengwas not significantly different from fatigue on placebo.
