Rosenroot (Rhodiola rosea): traditional use, chemical composition, pharmacology and clinical efficacy

This comprehensive systematic review examined rhodiola rosea's traditional use, pharmacology, and clinical evidence across multiple studies. The review included human trials for stress, fatigue, depression, and cognitive performance.

Evidence consistently showed that rhodiola reduces physical and mental fatigue, improves stress resilience, enhances cognitive function under stress, and may have antidepressant effects. Clinical trials demonstrated improvements in attention, processing speed, and accuracy during mental fatigue. Doses of 200-600mg daily were most commonly used.

Rhodiola's active compounds (rosavins and salidrosides) appear to work by modulating stress response systems, including the HPA axis and key neurotransmitters like serotonin and dopamine. The herb demonstrates adaptogenic properties, helping normalize physiological functions disrupted by stress. Rhodiola was particularly effective for fatigue-related cognitive impairment and maintaining performance under demanding conditions. The supplement showed excellent safety across studies.
