Rhodiola rosea ("golden root" or "Arctic root") is widely distributed at high altitudes in Arctic and mountainous regions throughout Europe and Asia. It is a popular plant in traditional medical systems in Eastern Europe and Asia, with a reputation for stimulating the nervous system, decreasing depression, enhancing work performance, eliminating fatigue, and preventing high altitude sickness.1 In addition to Rhodiola rosea, over 200 different species of Rhodiola have been identified and at least 20 are used in traditional medical systems in Asia, including R. alterna, R. brevipetiolata, R. crenulata, R. kirilowii, R. quadrifida, R. sachalinensis, and R. sacra.
