This was posted by another gal from another board I go to. Just thought I would pass it along. This is from the book "Hope and Help for Chronic Fatigue Syndrom and Fibromyalgia" but I have also read about it in Suzane Sommers new book "Ageless: the Naked Truth About Biodentical Hormones" as she takes it herself and most antiaging doctors and other doctors interviewed in her book recommend this herb: " This is probably the most exciting botanical to come to the North American market in recent years. Unlike many herbs, the clinical potential of rhodiola is backed up by some well-designed human studies. Rhodiola is an herb that has been studied intensively in Russian scientific laboratories over the last forty years. It has been used traditionally to enhance work performance and energy and decrease irritability under stressful conditions as well as physical and mental strain and viral exposure. Rhodiola is a classic adaptogen and based on its historical use, partivularly postviral/stress, it may be the most appropriate herb for CFS/FM patients. Rhodiola has been the subject of clinical research, the results of which seem to verify its traditional use. Two double-blind, placebo controlled trials of rhodiola extract appeared in Western scientific journals in 200. The first study showed that the rhodiola group (170 mg per day) had statistically significant improvements in mental performance and measures of fatigue versus a placebo among medical doctors working night call rotations. The second trial involved medical students during a stressful exam period. The three week study showed that those who received 100 mg of rhodiola had significant improvements in physical fitness, mental performance, sleep patterns, motivation to study, and general well-being. Those taking rhodiola also reported less need for sleep, greater mood stability, and reductions in mental fatigue versus those on placebo. In 2003, a joint Russian-Swedish study showed that just one dose of rhodiola given during stressful conditions could improve mental function versus placebo. This study, again double blind and placebo-controlled, showed that single doses of rhodiola (370 or 555mg) given at four o'clock in the morning could improve capacity for mental work and that rhodiola produces a pronounced antifatigue effect as reflexed in an anti-tagieu indes (AFI). In fact there was a trend for the lower dose to be more effective. It seems that higher doses do not enhance the adaptogenic effects of rhodiola. There have been no significant side effects noted for rhodiola at the dosage levels used in the clinical trials. Based on these intial studies in healthy adults, investigations into the usefulness of rhodiola in cases of CFS/FM seem rational. Supplementation with rhodiola has not been evaluated in pregnancy and lactation and should therefore be avoided during these times."
