Effects of Rhodiola rosea on level of 5-hydroxytryptamine, cell proliferation and differentiation, and number of neuron in cerebral hippocampus of rats with depression induced by chronic mild stress
Zhongguo Zhong Yao Za Zhi. 2008; Division of Neurosciences, Department of Histology and Embryology, Zhongshan School of Medicine, Sun Yat-sen University, Guangzhou, China.
To explore the effects of Rhodiola rosea on the level of 5-hydroxytryptamine (5-HT), cell proliferation and differentiation, and number of neuron in cerebral hippocampus of rats with depression induced by chronic mild stress. Fifty rats were divided into 5 groups: normal control, untreated, negative control, positive control and Rhodiola rosea-treated groups. There were 10 rats in each group. Except for normal control group, depression was induced in rats by chronic mild stress. The depressive rats in the other four groups were intragastrically administered with 0.5% sodium carboxymethycellulose, fluoxetine and Rhodiola rosea for 3 weeks. After the treatment, the content of 5-HT in the hippocampus was detected by high-performance liquid chromatography. The proliferating cells and differentiated cells in the hippocampus were labeled by bromodeoxyuridine (BrdU) or/and beta-tubulin III immunohistochemistry, and the number of hippocampal neurons was counted by morphometry. Compared with the normal control group, the content of 5-HT, number of BrdU positive cells, percentage of BrdU and beta-tubulin III double labeled cells and number of neurons in cerebral hippocampus in the Rhodiola rosea-treated group were increased and recovered to normal level. Rhodiola rosea may enhance the level of 5-HT and promote the proliferation and differentiation of neural stem cells in the hippocampus of the depressive rats, and may play a role in saving injured neurons of the hippocampus.
Rhodiola extract shows some promise to combat cancer. Antitumor and antimetastatic effects of an official extract of Rhodiola rosea were established in experiments on inbred and noninbred mice and rats with transplantable NK/Ly tumor, Ehrlich's adenocarcinoma, melanoma B16 and Lewis lung carcinoma. Application of the said preparation was followed by an increase in survival.
Oral administration of Rhodiola rosea extract to a small group of patents (n = 12) with superficial bladder carcinoma (T1G1-2) improved the characteristics of the urothelial tissue integration, parameters of leukocyte integrins and T-cell immunity. The average frequency of relapses for these patients has been found to fall twice, though statistical differences were not significant.
Rhodiola capsules decrease the oxygen consumption of myocardium and oxygen consumption index in anesthetic dogs, decrease the coronary artery resistance, but have no marked effect on the coronary artery blood flow. The capsules also have the function of decreasing blood pressure and slowing heart rate.
Rhodiola and depression
an extract of rhodiola rosea roots and rhizomes has shown benefit in patients with mild to moderate depression. A double-blind, randomized, placebo-controlled study of rhodiola rosea in patients diagnosed with depression, published in the Nordic Journal of Psychiatry, utilized a proprietary Rhodiola rosea root extract called SHR-5, a standardized extract used in the product Arctic Root produced by the Swedish Herbal Institute in Gothenburg, Sweden. The 6-week trial was conducted on 89 subjects, aged 18 to 70, who had clinical depresson. Patients were randomly assigned to one of three groups. The first group received 2 tablets once daily (340 mg/day) of SHR-5, the second group received 2 tablets twice daily (680 mg/day) of SHR-5, and the third group was given 2 placebo tablets once daily.
Monoamine oxidase inhibition by Rhodiola rosea L. roots.
J Ethnopharmacol. 2009. van Diermen D, Marston A, Bravo J, Reist M, Carrupt PA, Hostettmann K. Laboratory of Pharmacognosy and Phytochemistry, School of Pharmaceutical Sciences, University of Geneva, University of Lausanne, Quai Ernest-Ansermet Geneva 4, Switzerland.
Rhodiola rosea is traditionally used in Eastern Europe and Asia to stimulate the nervous system, enhance physical and mental performance, treat fatigue, psychological stress and depression. In order to investigate the influence of Rhodiola rosea L. roots on mood disorders, three extracts were tested against monoamine oxidases (MAOs A and B) in a microtitre plate bioassay. Methanol and water extracts gave the highest inhibitory activity against MAOs. The methanol and water extracts exhibited respectively inhibitions of 92% and 84% on MAO A and 81% and 88% on MAO B, at a concentration of 100mug/ml. The most active compound (rosiridin) presented an inhibition over 80% on MAO B). The present investigation demonstrates that Rhodiola rosea L. roots have potent anti-depressant activity by inhibiting MAO A and may also find application in the control of senile dementia by their inhibition of MAO B.
Memory and Learning
Studies with mice did not show rhodiola extract to have much of an effect on memory.
Stress and Fatigue
Rhodiola extract may be helpful in increasing energy and decreasing mental fatigue. The objective was to investigate the stimulating and normalizing effect of the adaptogen Rhodiola rosea extract SHR-5 in foreign students during a stressful examination period. The study was performed as a double-blind, randomized and placebo-controlled with low repeated dose regime. The study drug and the placebo were taken for 20 days by the students during an examination period. The physical and mental performance were assessed before and after the period, based on objective as well as on subjective evaluation. The most significant improvement in the SHR-5 group was seen in physical fitness, mental fatigue and neuro-motoric tests. The self-assessment of the general well-being was also significantly better in the verum group. No significance was seen in the correction of text tests or a neuro-muscular tapping test. The overall conclusion is that the study drug gave significant results compared to the placebo group but that the dose level probably was suboptimal.
This was another study with doctors working night shift in a hospital. The aim of this study was to investigate the effect of repeated low-dose treatment with a standardized extract SHR/5 of rhizome Rhodiola rosea L, (RRE) on fatigue during night duty among a group of 56 young, healthy physicians. The effect was measured as total mental performance calculated as Fatigue Index. The tests chosen reflect an overall level of mental fatigue, involving complex perceptive and cognitive cerebral functions, such as associative thinking, short-term memory, calculation and ability of concentration, and speed of audio-visual perception. These parameters were tested before and after night duty during three periods of two weeks each: a) a test period of one RRE/placebo tablet daily, b) a washout period and c) a third period of one placebo/RRE tablet daily, in a double-blind cross-over trial. The perceptive and cognitive cerebral functions mentioned above were investigated using 5 different tests. A statistically significant improvement in these tests was observed in the treatment group (RRE) during the first two weeks period. No side-effects were reported for either treatment noted. These results suggest that RRE can reduce general fatigue under certain stressful conditions.
What's in Rhodiola extract?
There are dozens of substances in Rhodiola and it is difficult to say which are the active ingredients. The dried rhizomes contain 0.05% essential oil with the main chemical classes: monoterpene hydrocarbons (25.40%), monoterpene alcohols (23.61%) and straight chain aliphatic alcohols (37%). n-Decanol (30%), geraniol (12%) and 1,4-p-menthadien-7-ol (5%) were the most abundant volatiles detected in the essential oil, and a total of 86 compounds were identified. Geraniol was identified as the most important rose-like odour compound besides geranyl formate, geranyl acetate, benzyl alcohol and phenylethyl alcohol. Floral notes such as linalool and its oxides, nonanal, decanal, nerol and cinnamyl alcohol highlight the flowery scent of rose root rhizomes. Additional molecules include rosavin, rosin, and rosarin, salidroside and lotaustralin.
Rhodiola is sold in capsule, tablet, and tea form. Dosage ranges from 100 to 400 mg a day.
Rhodiola for more stamina?
Rhodiola rosea, also known as golden root, grows in the Arctic regions of eastern Siberia. Rhodiola is a popular plant in traditional medical systems in Eastern Europe and Asia. Russians have drunk rhodiola tea for centuries as an energy booster. Russian and Chinese scientists have researched the benefits of Rhodiola for several decades. The purpose of this study conducted at Katholieke Universiteit Leuven in Belgium. was to two-fold. To investigate the effect of acute and long term 4-week Rhodiola rosea intake on physical capacity, muscle strength, and reaction time. During the acute phase of the study, subjects were given 200-mg of Rhodiola rosea extract and the results compared a few days later when they were given placebo pills. Subjects given rhodiola had sligthly more stamina. The time to exhaustion during exercise was 17.2 minutes compared to 16.8 min on placebo. Also, lung ventilation capacity improved during rhodiola treatment. In a second phase of the study, subjects subjects ingested 200 mg of rhodiola for 4 weeks. The results showed that there was no difference in stamina when compared to placebo.
It appears that Rhodiola rosea intake for a day or two can improve endurance exercise capacity, but long term use does not make much of a difference. Perhaps using lower dosages may have been more effective since high dosages can cause insomnia and reduce energy levels. Practically speaking, it would make sense to take breaks from use. Perhaps this recommendation could also apply to ginseng and other adaptogens.
Q. Does rhodiola help with weight lose, burn fat?
A. We are not aware of research regarding the role of rhodiola and weight loss or fat burning.
Q. Shouldn't rhodiola extract have
a contraindication for individuals taking antidepressants?
A. Many herbs that have stimulant type properties may interact with antidepressants, but generally not in a significant manner if the dosage of the herbs is low.
Q. According to an
states that "Starting in the brain stem, Rhodiola rosea promotes release of
norepinephrine, serotonin, and dopamine in ascending pathways that activate the
cerebral cortex and the limbic system. Consequently, the cognitive (thinking,
analyzing, evaluating, calculating, and planning) functions of the cerebral
cortex and the attention, memory, and learning functions of the prefrontal and
frontal cortex are enhanced." Therefore, I do understand that rhodiola rosea
improves prefrontal cortex function. However, I am unclear if this also applies
to use of rhodiola rosea for prefrontal cortex function dysfunction caused by
sleep deprivation. In other words, when a person has sleep loss and therefore
has prefrontal cortex function impairment, does consumption of rhodiola rosea
help to reverse this impairment?
A. Rhodiola extract does cause alertness as do many herbs such as ginseng. Rhodiola rosea may be appropriate to take at times during the day if there has been inadequate sleep and alertness is required, but the most important thing is not to take too much so that it is out of the system by bedtime and sleep is not interfered with.

Q. What is rhodiola Arctic root?
A. Arctic Root is a registered rhodiola rosea product trademark. Apparently a person with the name Georg Wikmann of Swedish Herbal Institute invented the term in the early 1960's in Russia.
Q. I recently read in 2007 an article on rhodiola
extract in Science News which states that in 1989 the then Soviet government
standardized the supplement to contain 3% rosavins. I then looked at a couple of
rhodiola extract supplements on-line and found that many of them claim to
contain 4% rosavins ( and something called a salidroside,
usually at 1%). My question is that your product information states the content of your supplement to contain only 0.8% rosavins as well as 0.8% salidrosides. The dosages you recommend also differ, although they sound more conservative, they may be a more informed and cautious approach. Could you please explain the discrepancies I have found between your product and these others. Understandably, you can only speak directly about your own, but perhaps you may have some insight as to the practices of other manufacturers or suppliers.
A. A long time ago most herbs used to be available only as regular powder or leaf form, or as tinctures. Now, almost every herb has different extract concentrations. Different raw material suppliers will have different extract concentrations of rhodiola or other herbs. Since human research with these various extract potencies is limited, it is difficult to claim that one extract percentage or potency is better than another. Sometimes if an herbal extract is too concentrated and of high potency, it can cause more side effects. Just because one organization or one country has chosen a particular extract percentage as a standard does not mean that particular extract is the best option. Different scientists, organizations, and medical doctors can have different viewpoints on this topic. The bottom line is that the ideal extract potency is what works for any particular person rather than what is recommended or chosen by an organization. And the only way for a consumer to tell is to try the product in various dosages to see which amount works best for their unique condition.
Q. I just received my order of rhodiola rosea
extract. i have a question. On one website says to take "one half tablet to one
full tablet one time per day." but the bottles suggested use says " take 2
rhodiola rosea tablets twice daily." This is quite a discrepancy in dosage info,
a half tablet as opposed to up to 4 tablets daily.
A. This rhodiola rosea extract product is made by Planetary Formulas. Manufacturers place suggested guidelines for usage for their products that sometimes are too high. Our research staff is more cautious and we want people to avoid side effects, especially people who are very sensitive to herbs. As such we prefer people use lower amounts of rhodiola rosea extract until they get a good sense of how it is working for them and whether they are getting any side effects of overstimulation or rapid heart beat.
Q. Is rhodiola an erectile dysfunction herb?
A. Yes, it can, but keep the dosages low until you learn how each one is influencing you. Some people are very sensitive to herbs and others need larger amounts to notice an effect. Rhodiola may slightly help with erectile dysfunction but other herbs are more potent.
Q. Can you tell me where I can just rhodiola rosea
(nothing else) in a capsule of 100 mg or there about that was grown in Siberia?
I've spent some time trying to find this can so far I've not been able to find
A. We are not familiar with a 100 mg rhodiola rosea dosage capsule, but if search the internet, there may be a product out there that has 100 mg of this herb. However, we don't see why 100 mg would be so important. There is no exact dosage of any herb that is better than another dosage. A wide range of dosages are acceptable with herbs as opposed to pharmaceutical medicines.
I Googled “Rhodiola rosea and coumadin” and got:
Rhodiola Complex. Rhodiola herb has few side effects;
however the herb may thin your blood, so discontinue use before surgery and
consult your doctor if you take blood-thinning medications like Coumadin (warfarin)
or supplements like vitamin E. What are your thoughts about combining Coumadin
warfarin with rhodiola rosea extract?
There are many herbs that have blood thinning potential. Whether rhodiola rosea has more potent blood thinning potential than other herbs such as ginkgo or garlic is difficult to say. Herbs should be used cautiously by those on Coumadin. We have not seen direct studies regarding the role of rhodiola rosea supplements on blood clotting parameters.
I was wondering if there are any drug interaction
problems with Rhodiola Rosea. I also have been taking Goji, Glucosamine and
Chondroitin, a Hair, Skin and Nail supplement and I also take Prilosec.
There are too many variables involved to be able to give a simple answer.
