Eleutherococcus senticosus, commonly known as Siberian ginseng, is an herb used in traditional medicine to combat fatigue. It is an adaptogen compound.
Preliminary evidence suggests that Eleutherococcus senticosus can improve physical performance during periods of high intensity exercise. Unfortunately, this effect is not very reliable. The studies that showed the most promise for Eleutherococcus senticosus also had the worst methodology. Though additional research is needed to confirm Eleutherococcus senticosus’s ergogenic effect, it cannot be disproven either.
Preliminary in vitro (outside the body) and animal research suggests Eleutherococcus senticosus supplementation can provide a variety of protective effects for cognition, meaning it can protect the brain from harm. Again, further research is needed to confirm these effects.
