Double-blind, placebo-controlled clinical trial comparing a clean, whole root red ginseng (HRG80) versus standard white ginseng and placebo
50 healthy adults ages 18-65 who had very stressful, mentally demanding office work, took each treatment in turn for 12 days, with a two week wash-out between each phase
While taking each treatment (red ginseng, white ginseng, or placebo (rice flour), the participants completed mental and stress tests in the morning and after a day’s work
While taking red ginseng, the participants had significant improvement in their mental focus and made fewer errors on the mental assessment tests –results were detectible on the first day of use!
When taking white ginseng or placebo, their mental assessment scores got worse
Both red and white ginseng reduced stress levels, but significant reductions were seen by day 5 with red ginseng and not until day 12 for white ginseng
Dosage was 200 mg daily of the red ginseng, and no significant adverse effects were reported
