A systematic review of randomized clinical trials shows that the herb Rhodiola rosea improves physical and mental performance and improves mental health
Researchers at the University of Exeter, in the UK critically assessed the current evidence from randomized clinical trials for or against the effectiveness or efficacy of Rhodiola rosea. Systematic literature searches were performed in six electronic databases: AMED (1985-July 2009), CINAHL (1982-July 2009), The Cochrane Library (search in July 2009), EMBASE (1974-July 2009), MEDLINE (1950-July 2009) and Web of Science (searched in July 2009).
Eleven randomized clinical trials met the inclusion criteria; all were placebo-controlled. Six trials investigated the effects of Rhodiola rosea on physical performance, four on mental performance, and two in patients diagnosed with mental health condition.
Rhodiola rosea had beneficial effects on physical performance, mental performance, and certain mental health conditions according to the data in these studies. The review is published in the journal Phytomedicine, October 29th, 2010 [Epub ahead of print].
