A plant native to mountainous regions of Asia, parts of Europe, and the Arctic, Rhodiola rosea has long been used as a healing herb. Traditionally it is often recommended to help combat fatigue and restore energy.
Although records show that the ancient Greek physician Dioscorides once prescribed this plant, it is primarily associated with Scandinavia and Russia. Swedish researchers, for instance, believe that the Vikings regularly used rhodiola. And even today, a bouquet of rhodiola may be presented to a bride and groom in Siberia to assure a rich and fruitful marriage.
Given the plant's origins, it's not really surprising that most of the research on Rhodiola rosea has been published in Slavic and Scandinavian languages. American and other Western researchers, however, have recently begun to explore rhodiola's effect on the body and its capacity to aid in the healing process, building upon the clinical studies originally conducted in Scandinavian countries and the Soviet Union.
Of particular interest is rhodiola's well-documented qualities as an adaptogen (an endurance enhancer). In this capacity it appears to help the body stay healthy and perform in top-notch condition despite physical exhaustion or environmental stresses, such as high heat or pollutants in the air and water.
Plant specialists have actually identified more than 200 different species of rhodiola. While a number of different ones are used in traditional healing, R. rosea appears to be the most clinically effective form. The root is the part of the plant used medicinally, and some sources refer to R. rosea as "golden root" or "Arctic root."
In recent years, dozens of uses for Rhodiola rosea have been proposed, including treating depression and fatigue, enhancing memory and intellectual capacity, increasing work performance and endurance, and stimulating the nervous system. Many of these potential benefits relate to the herb's adaptogenic qualities.
One particularly interesting aspect of rhodiola is that it appears to work differently within the body than other adaptogens--the best known of which is the very popular herb Siberian ginseng. Rhodiola's unique mechanism of action excites researchers because it means this herb may be able to provide a therapeutic alternative to established adaptogens.
Some of the current findings on rhodiola are still preliminary and relate to complex physiological interactions in the body's chemistry. But put simply, rhodiola appears to work by influencing key central nervous system chemicals--neurotransmitters called monoamines (dopamine and serotonin are examples). An imbalance of monoamines is believed to be involved in several hard-to-treat illnesses, such as fibromyalgia, chronic fatigue syndrome, and seasonal affective disorder (SAD); some herbalists believe taking rhodiola to normalize monoamine levels may benefit these ailments.
In contrast, most other adaptogens, such as Siberian ginseng, seem to boost the body's reserves by enhancing the output of stress-fighting hormones from the adrenal glands.
Other studies on rhodiola have shown benefits in such varied areas as increased learning capacity and memory enhancement, regulation of menstrual periods and infertility, reduction of side effects from cancer chemotherapy, increased strength and dysfunction, enhancement of thyroid gland function, increased capacity for work and endurance, and protection from environmental toxins.
