Rhodiola is an adaptogenic herb which grows in the arctic regions of Eastern Siberia. The variety called Rhodiola rosea has long been studied by Russian scientists. Now that the Cold War has ended, more information has become available and further research undertaken to learn more about the physical and psychological actions of rhodiola. It looks promising that the herb may help with several important energy functions.
History
In 1947, adaptogens were discovered by Dr. Nicolai Lazarev, a Russian scientist, who became the mentor of Dr. Israel Brekhman. Dr. Brekhman continued Lazarev's research and became known as a leading expert on adaptogens. Adaptogens are considered to have a broad spectrum of healing actions, but their most unique property is in the stress-relief category. "First-generation" adaptogens are herbs such as Panax ginseng, American ginseng and Siberian ginseng. Rhodiola rosea, also called golden root, is considered to be a "second generation" adaptogen.
Weight Loss
There is little research to support that Rhodiola helps with weight loss, but clearly more studies are needed. It may help in an indirect way by improving energy and stamina. Fat is stored in adipose tissue. Lipase plays an important role in breaking down that fat. A 1999 study by Zakir Ramazanov, published by ATN/Safe Goods Publishing, showed that Rhodiola rosea did activate lipase to break down stored fat. A study led by Katrein De Bock, reported in the International Journal of Sports Exercise Metabolism in 2004, showed Rhodiola improved endurance exercise performance in young, healthy volunteers.
Stress
Adaptogens are natural plants which bolster the body's ability to handle both external and internal stress factors and maintain homeostasis. In 2002, Dr. Richard Brown of Columbia University published a paper, "A Phytomedicinal Overview," citing different studies on Rhodiola. Brown reports that Rhodiola provides both "emotional calming" and "cognitive stimulation" as well as adds to long-term maintenance of brain function.
Other Effects of Rhodiola
Based on preliminary research, the standardized extract of Rhodiola rosea root may be therapeutic in asthenic conditions such as sleep disturbances, poor appetite, irritability, headaches and fatigue. Rhodiola may also offer anti-cancer activity; when lab rats were injected with cancer cells and Rhodiola was added to chemotherapy treatment, the treatment was enhanced. Other early research shows that Rhodiola may increase energy and mental clarity. Further research is needed into these possible health benefits.
Dosage and Side Effects
The average dose of Rhodiola rosea is between 200 and 400 mg/day of an extract standardized to contain rosavins and salidrosides in a 3:1 ratio. The herb is considered safe, but in high doses of 1.5 to 2 g per day it can cause irritability. Because of its mild energizing effect, it should be taken in the morning or by midday. It has not been studied in pregnant women and should not be used by them.
