Rhodiola rosea (Golden Root, Roseroot, Aaron's Rod) is a plant in the Crassulaceae family that grows in cold regions of the world. These include much of the Arctic, the mountains of Central Asia, the Rocky Mountains, and mountainous parts of Europe, such as the Alps, Pyrenees, Carpathian Mountains, Scandinavia, Iceland, Great Britain and Ireland.
Rhodiolarosea L. (Crassulaceae) is traditionally used in Eastern Europe and Asia to stimulate the nervous system, enhance physical and mental performance, treat fatigue, psychological stress and depression. Rhodiola rosea contains a variety of compounds that may contribute to its effects, including the class of rosavins which include rosavin, rosarin, and rosin. Several studies have suggested that the most active components are likely to be rhodioloside and tyrosol, with other components being inactive when administered alone, but showing synergistic effects when a fixed combination of rhodioloside, rosavin, rosarin and rosin was used.
