Rhodiola is a hardy perennial herb known botanically as Rhodiola rosea, a member of the Crassulaceae family native to arctic and mountainous regions of Europe, Asia, and North America. It has fleshy leaves, yellowish flowers, and a thick root that is the part traditionally used.
In traditional northern and Eurasian herbal practice, rhodiola root has been valued as a tonic herb associated with stamina, resilience, and adaptation to harsh climates. It is most commonly prepared as a tincture, decoction, extract, or powder.
The root is notable for its faint rose-like fragrance when freshly cut, which is reflected in the species name rosea.
