Researchers conducted a review of 11 randomized placebo-controlled human studies on the adaptogen Rhodiola. Of these 11 studies, six investigated the effects of Rhodiola on physical performance. Four of them looked at mental performance. And two of them focused on patients diagnosed with a mental health condition.

The reviewers found that the Rhodiola clearly had beneficial effects on physical performance, mental performance, and certain mental health conditions.

And it reduced their ability to recover from sleep deprivation.

Researchers from the University of Salford in Manchester, England gave the Bilharzia parasite to a strain of rats that cannot make nitric oxide. This strain of rat is highly susceptible to infection and the severe pathology caused by the parasite. When the researchers returned nitric oxide levels to normal in these rats, they recover their natural resistance to the parasite.
