Rhodiola: Science and Safety

https://www.nccih.nih.gov/health/rhodiola?nav=govd Background Rhodiola grows in cold regions and at high altitudes in Europe and Asia. People have traditionally used it to try to increase endurance, work performance, and tolerance of high altitudes and to treat fatigue, weakness, and other symptoms. Today, rhodiola is promoted to increase energy, stamina, strength, and mental capacity; improve athletic performance; resist the effects of stress; and help manage depression, anxiety, and other symptoms. What Have We Learned? Some preliminary research has been done on rhodiola, but few rigorous studies of this herb have been done in people. There isn’t enough evidence from studies in people to allow conclusions to be reached about whether rhodiola is helpful for any health-related purpose. What Do We Know About Safety? Rhodiola has been used safely in studies lasting 6 to 12 weeks. Little is known about whether it’s safe to use rhodiola during pregnancy or while breastfeeding.
