Common Names: arctic root, golden root, rose root, king’s crown

Latin Names: Rhodiola rosea


  • Rhodiola grows in cold, mountainous regions of Europe, Asia, and high altitudes in the Arctic.
  • Historically, people in northern regions have used rhodiola for anxiety, fatigue, anemia, impotence, infections, headache, and depression related to stress. People also have used it to increase physical endurance, work performance, longevity, and improve resistance to high-altitude sickness.
  • Today, people use rhodiola as a dietary supplement to increase energy, stamina, and strength, to improve attention and memory, and to enhance the ability to cope with stress.
  • Rhodiola root extracts are also available in capsule or tablet form.

How Much Do We Know?

  • There have been some studies of rhodiola in people; however, the quality of research is limited so firm conclusions about its effectiveness can’t be made.

What Have We Learned?

  • Two review articles—published in 2011 and 2012—looked at 15 studies that tested rhodiola on physical and mental performance in 575 people. Both reviews found evidence that rhodiola may enhance physical performance and ease mental fatigue, but emphasized that the limited quantity and quality of available evidence did not allow firm conclusions to be made.
  • A small, NCCIH-supported study tested rhodiola against the drug sertraline and a placebo in people with mild-to-moderate major depressive disorder. The 2015 study results showed all were similarly effective in reducing depressive symptoms, but people who took rhodiola had fewer side effects than those who took sertraline. However rhodiola’s effectiveness and safety for depression need testing in larger, more powerful studies.

What Do We Know About Safety?

  • When taken orally (by mouth), rhodiola may cause dizziness and dry mouth.

Keep in Mind

  • Tell all your health care providers about any complementary or integrative health approaches you use. Give them a full picture of what you do to manage your health. This will help ensure coordinated and safe care.
