Ginsenoside Rg1 can reverse fatigue behavior in CFS rats by regulating EGFR and affecting Taurine and Mannose 6-phosphate metabolism

Abstract:

Background: Chronic fatigue syndrome (CFS) is characterized by significant and persistent fatigue. Ginseng is a traditional anti-fatigue Chinese medicine with a long history in Asia, as demonstrated by clinical and experimental studies. Ginsenoside Rg1 is mainly derived from ginseng, and its anti-fatigue metabolic mechanism has not been thoroughly explored.

Methods: We performed non-targeted metabolomics of rat serum using LC-MS and multivariate data analysis to identify potential biomarkers and metabolic pathways. In addition, we implemented network pharmacological analysis to reveal the potential target of ginsenoside Rg1 in CFS rats. The expression levels of target proteins were measured by PCR and Western blotting.

Results: Metabolomics analysis confirmed metabolic disorders in the serum of CFS rats. Ginsenoside Rg1 can regulate metabolic pathways to reverse metabolic biases in CFS rats. We found a total of 34 biomarkers, including key markers Taurine and Mannose 6-phosphate. AKT1, VEGFA and EGFR were identified as anti-fatigue targets of ginsenoside Rg1 using network pharmacological analysis. Finally, biological analysis showed that ginsenoside Rg1 was able to down-regulate the expression of EGFR.

Conclusion: Our results suggest ginsenoside Rg1 has an anti-fatigue effect, impacting the metabolism of Taurine and Mannose 6-phosphate through EGFR regulation. This demonstrates ginsenoside Rg1 is a promising alternative treatment for patients presenting with chronic fatigue syndrome.

Panax ginseng improves physical recovery and energy utilization on chronic fatigue in rats through the PI3K/AKT/mTOR signalling pathway

Abstract:

Context: Panax ginseng C. A. Meyer (Araliaceae) is a tonic herb used in ancient Asia.

Objective: This study investigated the antifatigue effect of P. ginseng on chronic fatigue rats.

Materials and methods: Sprague-Dawley rats were divided into control, model and EEP (ethanol extraction of P. ginseng roots) (50, 100 and 200 mg/kg) groups (n = 8). The rats were subcutaneously handled with loaded swimming once daily for 26 days, except for the control group. The animals were intragastrically treated with EEP from the 15th day. On day 30, serum, liver and muscles were collected, and the PI3K/Akt/mTOR signalling pathway was evaluated.

Results: The swimming times to exhaust of the rats with EEP were significantly longer than that without it. EEP spared the amount of muscle glycogen, hepatic glycogen and blood sugar under the chronic state. In addition, EEP significantly (p < 0.05) decreased serum triglycerides (1.24 ± 0.17, 1.29 ± 0.04 and 1.20 ± 0.21 vs. 1.58 ± 0.13 mmol/L) and total cholesterol (1.64 ± 0.36, 1.70 ± 0.15 and 1.41 ± 0.19 vs. 2.22 ± 0.19 mmol/L) compared to the model group. Regarding the regulation of energy, EEP had a positive impact on promoting ATPase activities and relative protein expression of the PI3K/Akt/mTOR pathway.

Conclusions: Our results suggested that EEP effectively relieved chronic fatigue, providing evidence that P. ginseng could be a potential dietary supplement to accelerate recovery from fatigue.

Semen raphani weakened the action of ginseng under chronic fatigue condition

Abstract:

Ethnopharmacological relevance: Fatigue is a kind of subhealth status and people paid much more attention on it. Ginseng is used to treating fatigue as a kind of qi -tonifying drug in Chinese medicine. In the traditional applications, there is a viewpoint that ginseng could not be used with semen raphani and supposed that semen raphani is a kind of qi regulating drug, which will reduce the qi invigorating effect of ginseng. However, the underlying combination mechanism of the two drugs remained unclear.

Aim of the study: The aim of this study is to explore whether ginseng can be used with semen raphani or not to remedy acute and chronic fatigue conditions.

Methods: We used normal and weight-bearing swimming method combined with appetite control animals. The biochemical indexes in energy metabolism, antioxidant, regulating endocrine system and immunity capacities were performed to explore the antagonism effect of semen raphani on ginseng under acute and chronic fatigue conditions. The serum and urine metabolomics were investigated using liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QTOF/MS). Fecal flora was analyzed via 16S rRNA amplicon sequencing.

Results: The combination of ginseng with semen raphani have no influence on acute fatigue effect compared with ginseng alone. Both can improve the exhausted swimming time, the activity of GSH-Px, LDH and Na+-K+-ATPase. Furthermore, the combination of ginseng with semen raphani can increase the urine volume of rats and down-regulate the content of AQP-3, which can alleviate the “fireness” side-effect of ginseng. But the abundance and diversity of bacterial are decreased under acute fatigue experiment. Both the combination of ginseng with semen raphani and ginseng alone can remedy chronic-fatigue. They can also regulate the endocrine system, immune system, citric acid cycle metabolism, tryptophan metabolism, fatty acid metabolism, glycolysis/gluconeogenesis, etc. Furthermore, they can promote substance metabolism and energy metabolism in qi deficiency rats, and increase the abundance and diversities of the flora. While with the increased content of semen raphani, the combination of ginseng and semen raphani weaken the capacity of antioxidant, lactic acid metabolism, energy metabolism, flora diversity and regulation of endocrine system.

Conclusion: Compared with ginseng alone, the combination of ginseng with semen raphani can weaken the qi invigorating ability under chronic fatigue condition. The more ratios of semen raphani is in the combination of the two drugs, the less the power of treating chronic fatigue is. Compared with ginseng alone, the combination of ginseng with semen raphani have no influence on the qi invigorating ability under actue fatigue experiment. But the combination of ginseng with semen raphani will benefit for the “fireness” side-effect of ginseng.

Ginseng for the Treatment of Chronic Fatigue Syndrome: A Systematic Review of Clinical Studies

Abstract:

Background: Chronic fatigue syndrome (CFS) is a complex and often disabling chronic condition emerging worldwide, with no curative or definitive therapy yet identified. Ginseng has been widely used to treat fatigue in other patient groups and conditions; however, a systematic review focusing solely on the impact of ginseng on fatigue in patients with CFS has not been performed.

Objective: This study aimed to assess the current state of evidence regarding ginseng for CFS.

Methods: Multiple databases were searched from inception to October 2020. All data was extracted independently and in duplicates. Outcomes of interest included the effectiveness and safety of ginseng in patients with CFS.

Results: 2 studies enrolling 68 patients were deemed eligible, including one randomized clinical trial and one prospective observational study. The certainty of evidence in the effectiveness outcome was low and moderate from both studies, while the safety evidence was very low as reported from one study.

Conclusion: Study findings highlight a potential benefit of ginseng therapy in the treatment of CFS. However, we are not able to draw firm conclusions due to limited clinical studies. The paucity of data warrants limited confidence. There is a need for future rigorous studies to provide further evidence.

An Open-Label, Pilot Trial of HRG80™ Red Ginseng in Chronic Fatigue Syndrome, Fibromyalgia, and Post-Viral Fatigue

Abstract:

Chronic fatigue syndrome and fibromyalgia (CFS/FMS) affect 2.1% of the world’s population and ~10–25% of people who have had COVID-19. Previous clinical data suggested that a unique Panax ginseng (C.A. Meyer, family Araliaceae) root extract (HRG80™ Red Ginseng) often resulted in marked improvement. We aimed to study this hydroponic form of red ginseng root, containing high levels of rare ginsenosides, for improving energy, cognition, and stamina. This open-label prospective study included participants with severe CFS/FMS who took a daily supplement of HRG80 capsules (200–400 mg) or tablets (100–200 mg) for one month.
A total of 188 subject patients completed the one-month treatment trial. Of these, 60.1% rated themselves as improved, with 13.3% rating themselves as being much better. In this group, the mean composite score improved from 11.9 to 18.8 (p < 0.001), with a 67% average increase in energy, 44% average increase in overall well-being, 48% average improvement in mental clarity, 58% average composite improvement in the previous three measurements (primary outcome measure), 46% average improvement in sleep, 33% average decrease in pain, and 72% average increase in stamina. Our study showed that HRG80 red ginseng root powder resulted in a marked improvement in people with CFS and fibromyalgia. This included the subgroup with post-viral CFS/FMS.

Efficacy and safety of Sijunzi Decoction for chronic fatigue syndrome with spleen deficiency pattern: study protocol for a randomized, double-blind, placebo-controlled trial

Abstract:

BACKGROUND: Chronic fatigue syndrome (CFS), which is characterized by severe and disabling fatigue, has become an extensively concerned medical disorder in clinical practice. Due to the unclear etiology, current treatments are symptomatic or need assistance from psychology and kinesiology. Under the immature conditions in China, many patients would seek help from traditional Chinese medicine (TCM), in which Chinese herbal medicine (CHM) is one of the main interventions. Sijunzi Decoction (SJZD) is a classical formula and has been utilized in improving fatigue symptoms for a long time. However, lack of rigorously-designed randomized controlled trial limits its application and generalization in CFS management. Hence, we design this clinical trial to assess the effectiveness and safety of SJZD for CFS.

METHODS: This is a single-center, randomized, double-blind, placebo-controlled trial. Two hundred and twelve patients with CFS will be recruited from public and equally allocated to SJZD group and placebo group. Based on the general education, these two groups will receive corresponding drugs twice a day for consecutive 2 months. The follow-up period will be 1 month. The primary outcome will be the change of Chalder fatigue scoring after treatment. Secondary outcomes include the short form-36 physical function subscale (SF36-PF), spleen deficiency rating scale, quality of life and self-rated clinical global impression (CGI) scales.

DISCUSSION: The four ingredients of SJZD are Renshen (Radix Ginseng), Baizhu (Rhizoma Atractylodis Macrocephalae), Fulin (Poria) and Zhigancao (Radix Glycyrrhizae Preparata), which show potential to alleviate CFS on the foundation of available studies. The results of this trial will provide high-quality clinical evidence for the application of SJZD, and hope to further support a new TCM choice in CFS treatment.

The effective mechanism of the polysaccharides from Panax ginseng on chronic fatigue syndrome

Abstract:

Ginseng acidic polysaccharide WGPA isolated from the root of Panax ginseng C. A. Meyer was fractionated into WGPA-A and WGPA-N by anion-exchange chromatography. The antifatigue activity of ginseng acidic polysaccharide WGPA has been reported in our previous research. This present study was designed to identify its active component and elucidate the mechanism for preventing chronic fatigue syndrome (CFS).

WGPA, WGPA-A and WGPA-N were orally administered to mice once daily for 15 days. The effects of these compounds on physiological biomarkers of oxidative stress and on the morphology of the mitochondria in striated skeletal muscle were assessed. The results of forced swimming test-induced indicated that WGPA and WGPA-A could lengthen the swimming time, while WGPA-N could not. In addition, malondialdehyde and lactate dehydrogenase levels in serum were enhanced; while those of superoxide dismutase and glutathione peroxidase were lowered. Interestingly, the structural degeneration of mitochondria were all ameliorated.

These findings suggested that WGPA-A is the active component of WGPA, it might have potential therapeutic effects for CFS and the oxidative stress might be involved in the pathogenesis. Our results also provided essential data for a better understanding of the antifatigue effects of P. ginseng extracts.

Effects of a Chinese traditional formula Kai Xin San (KXS) on chronic fatigue syndrome mice induced by forced wheel running

Abstract:

ETHNOPHARMACOLOGICAL RELEVANCE: In traditional medicine, Kai Xin San (KXS), composed of ginseng (Panax ginseng), hoelen (Wolfiporia cocos), polygala (Polygala tenuifolia) and Acorus gramineus, is famous for the treatment of emotion-thought disease, such as settling fright, quieting the spirit and nourishing the heart.

AIM OF THE STUDY: The present study investigated the effect of KXS on chronic fatigue syndrome (CFS) mice induced by forced wheel running.

MATERIALS AND METHODS: Seventy two healthy adult male Kunming mice were randomly divided into six groups: home cage control group, CFS group, CFS group with Modafinil treatment at 13 mg/kg/d doge, KXS treatment at 175 mg/kg/d, 350 mg/kg/d and 700 mg/kg/d doge. CFS mice were induced by forced wheel running with higher speed for 4 weeks and then taken an exhausted exercise. The biochemical parameters including serum lactate dehydrogenase (LDH), serum urea nitrogen (SUN), serum testosterone (T), liver glycogen (LG), muscle glycogen (MG) and muscle lactic acid (MLA) were determined by using commercially available kits. The splenocytes proliferation from mice was examined by MTT method. The levels of interleukin-2 (IL-2) and interleukin-4 (IL-4) secreted by splenocytes were determined by ELISA.

RESULTS: CFS mice with KXS administration exhibited less electric shock time when compared with CFS group without drug treatment. The effect of KXS has after demonstrated reduction in SUN, LDH and MLA levels and an increase in T, LG and MG levels. CFS mice with KXS could improve the proliferation of splenocytes compared with CFS group without drug treatment. The cultured splenocytes from CFS mice without KXS supplementation produced more interleukin-2 (IL-2) but less interleukin-4 (IL-4) when compared with home cage control mice. The cultured splenocytes of CFS mice with KXS supplementation produced more interleukin-2 (IL-2) but less interleukin-4 (IL-4) when compared with CFS group without drug treatment.

CONCLUSIONS: The results of this preliminary study provide evidence that KXS could ameliorate CFS by affecting the physiological markers for fatigue. This study also supported the use of KXS against CFS by improving the proliferation of splenocytes from CFS mice and modulating the disturbance of cytokines induced by CFS.

The role of antioxidant properties of Nardostachys jatamansi in alleviation of the symptoms of the chronic fatigue syndrome

Abstract:

An experimental model of chronic fatigue syndrome (CFS) is utilized for evaluation of antidepressant, anti-stress effects, wherein the rat is forced to swim in water for 15 min/day on 21 consecutive days. Rats were divided into stressed control, stressed plus standard drug (Panax ginseng) and stressed plus 200 and 500 mg/kg of test drug, i.e., Nardostachys jatamansi extract (NJE) given orally.

The immobility during each 5 min periods of 0-5, 5-10 and 10-15 min of stress were noted. Similarly the climbing (struggling) behaviour was noted in the above four groups of rats in intervals of 5 min. The locomotor activity and also the anxiety state in animals were evaluated in an elevated plus maze after CFS in all the four groups. There was a significant increase in despair behaviour and anxiety in stressed control animals on successive days of CFS. Locomotor activity gradually decreased in stressed control group. Treatment with NJE (200 and 500 mg/kg) significantly reversed both paradigms.

Biochemical analysis showed that CFS significantly increased lipid peroxidation, nitrite and superoxide dismutase levels and decreased catalase level in rat brain. Administration of NJE (200 and 500 mg/kg) tended to normalize both augmented lipid peroxidation, nitrite, superoxide dismutase activities and catalase level significantly. NJE per se has an antioxidant effect. The results indicate that CFS may lead to oxidative stress, which is mitigated by NJE and so its antioxidant property may be responsible for anti-stress effect of NJE.

Brain atrophy in a murine model of chronic fatigue syndrome and beneficial effect of Hochu-ekki-to (TJ-41)

Abstract:

Brain-derived neurotrophic factor (BDNF) is associated with the main symptoms of chronic fatigue syndrome (CFS) and neuron apoptosis. Nevertheless, no study has been performed directly to explore the relationship between CFS, BDNF and neuron apoptosis.

We induced a CFS model by six injections of killed Brucella abortus antigen in BALB/c mice and treated them with Hochu-ekki-to (TJ-41). Daily running activity, body weight (BW), ratio of cerebral weight to BW (CW/BW) and expression levels of BDNF and Bcl-2 mRNA in the hippocampus were determined. The daily activity and CW/BW decreased significantly in the CFS model. BDNF and Bcl-2 mRNA expression levels in the hippocampus were suppressed in the CFS model and TJ-41 treated mice, while no significant difference was found between them.

We improved a murine model to investigate the relationship between CFS and brain dysfunction. In this model, reduced daily activity might have been associated with decreased hippocampal BDNF mRNA expression, hippocampal apoptosis and brain atrophy. TJ-41 increased the daily running activity of the model, which was independent of brain recovery.
