Rhodiola rosea (commonly golden root, rose root, roseroot, Aaron's rod, Arctic root, king's crown, lignum rhodium, orpin rose) is a perennial flowering plant in the family Crassulaceae. It grows naturally in wild Arctic regions of Europe, including Britain, Asia and North America, and can be propagated as a groundcover. Although it has long been used in traditional medicine for several disorders, notably including treatment of anxiety and depression, there is little scientific evidence to verify any benefit.
