Effect of Ginger and Novafen on menstrual pain: A cross-over trial

Ginger for Pain Management in Primary Dysmenorrhea: A Systematic Review and Meta-Analysis

Background: Primary dysmenorrhea is a common gynecological disorder that affects many women of reproductive age. Ginger, a widely used spice with anti-inflammatory properties, has been suggested as a potential treatment for the painful cramps associated with this condition. Objective: The aim of this systematic review and meta-analysis was to evaluate the efficacy of ginger for pain management in primary dysmenorrhea. Methods: Our systematic review was registered in Prospero (CRD42023418001). Six English (PubMed, Scopus, Web of Science, PsycINFO, CINAHL complete, and Cochrane) and one Persian electric database (SID) was searched up to May 2023 for English or Persian studies that measure the effect of ginger on pain in dysmenorrhea. The Cochrane tool was used to assess the risk of bias of the included studies. Random effects meta-analyses were performed to obtain standardized mean differences (SMD) and 95% confidence intervals (CI). Results: Out of the 804 articles initially identified from the search, 24 were included for qualitative analysis and 12 for quantitative analysis after a full-text evaluation. The combined results of the studies indicate that ginger is notably more effective than placebo in reducing both the intensity (SMD = -1.13; 95% CI = -1.59 to -0.68, I2 = 81.05%) and duration of pain (SMD = -0.29; 95% CI = -0.46 to -0.12). There were no differences between ginger and nonsteroidal anti-inflammatory drugs (NSAIDs) (SMD = 0.01; 95% CI = -0.24 to 0.25), or exercise (SMD = 0.06; 95% CI = -0.66 to 0.78) for pain intensity. Safety-related data were infrequently reported. Conclusions: The results of this meta-analysis suggest that ginger can effectively reduce pain associated with dysmenorrhea. The findings are limited due to risk of bias in the included studies and the unclear risk-benefit ratio.

Clinical dermatologic applications of ginger: a focused review

Ginger is a traditional herb with medicinal properties. Although most commonly utilized as a spice, it has been used for various medicinal ailments for thousands of years. Over the past century, the anti-inflammatory, antioxidative, and antimicrobial properties of ginger have been increasingly studied. Ginger has been demonstrated to be beneficial for many conditions including dermatologic, gastrointestinal, neoplastic, and respiratory diseases. Herein, we examine the existing literature regarding the clinical uses of ginger with a focus on its dermatologic applications.

Zingiber officinale Rosc. in the Treatment of Metabolic Syndrome Disorders-A Review of In Vivo Studies

Inflammation is a protective reaction of the innate immune system as a response to imbalances caused by a specific stimulus, a disease or a pathogen. A prolonged inflammatory condition may lead to the development of metabolic syndrome, which affects more than one-fourth of the world's population. This condition leads to the development of multi-organ disorders based on disrupted blood lipid and sugar levels, hypertension and oxidative stress. The review aims to present Zingiber officinale Rosc. as a plant that exhibits a variety of healing properties and restores the organism's equilibrium. Ginger (GI) rhizomes have been commonly used in traditional medicine to treat arthritis, stomach ache, nonalcoholic fatty liver disease, rheumatism, nervous system syndromes, asthma, diabetes and nausea caused by pregnancy or chemotherapy. This review gathers together data from in vivo experiments related to the application of ginger for the treatment of inflammatory conditions, obesity, diabetes and other related disorders as a consequence of metabolic syndrome, including the confirmed molecular mechanisms of action.

Comparison of herbal medicines and pain relief medications in the treatment of primary dysmenorrhoea among female medical students at Taibah University

Objectives

Dysmenorrhoea is a common gynaecological problem that affects many women during their reproductive years. The objectives of this study were to describe the different treatments used for primary dysmenorrhoea (PD) among medical students at Taibah University, and to investigate the link between pain severity and daily life activities in relation to the type of dysmenorrhoea treatment.

Methods

A cross-sectional study was conducted on 301 female medical students through an 18-item self-administered electronic questionnaire to screen for students with PD. The questionnaire included sociodemographic characteristics, details of self-management methods (types and adverse events), daily life domains affected by pain, and the Visual Analogue Scale score for the pain (wherein a score ≥7 indicated severe pain). Chi-square test, a multivariate regression model, and correlation analysis were used for data analysis.

Results

The prevalence of PD among respondents was 71.8%. Medications were used by more than half of the respondents (51.9%), and were mainly non-steroidal anti-inflammatory drugs (53.5%) and paracetamol (47.5%). Among the participants, 14.1% used herbal medicines, cinnamon (55.7%), chamomile (40.7%), and ginger (33.3%). Other pain relief modalities were used by 34% of participants. Most students with a history of PD (80.6%) reported effects on their daily activities, mainly mood disturbance. Students using medications were more likely to have severe pain (72.7%) and an affect on daily activities (92.9%) than those using herbal medicines (44.4% and 88.9%, respectively) and other treatments (47.7% and 70.8%, respectively) (p < 0.001).

Conclusions

Medications were more commonly used than herbal medicines and other relief methods. Effects of PD on daily life activities were observed among most students treated with medications. We recommend health promotion programmes to increase the awareness regarding different pain relief methods.

Effect of varash oil to decrease menstrual pain in primary dysmenorrhea of senior high school student at Palu City

OBJECTIVE

menstrual pain is a common gynecological symptom at women on or near their menstrual period. Two third of them experienced moderate to severe pain. However, just several seek for medical help. This research aims to know the effect of ginger oil used on decreasing menstrual pain scale.

MATERIALS AND METHODS

this cross over experimental study was held from February until May 2020 on 64 grade XI high school students at Palu city. Participants were grouping cluster randomly into group A which applied 5ml ginger oil five days before until the second day of the first menstrual period, and group B that given the same treatment in the next period. A visual pain scale measured the pain scale on the second day of the menstrual period.

RESULT

most participants were in the age of 17 years old. The study found a lowering of pain scale significantly at both groups after treatment. The main menstrual pain scale were 6.87 ± 1.817 and 6.46±1.362 decreased to 3.48±1.928 and 4.24±2.010 after treatment (p=0.0001). Differences between the two groups were significant in the first period (p=0.0001) but not significant in the second period (p=0.410).

CONCLUSION

the use of ginger oil several days before menstruation can reduce menstrual pain scale on students with primary dysmenorrhea; therefore, its use can be recommended to prevent the pain.

Efficacy of Ginger in the Treatment of Primary Dysmenorrhea: A Systematic Review and Meta-analysis

It has been evidenced that very few systematic reviews have examined the effectiveness of ginger for pain duration and its severity among women with primary dysmenorrhea. This meta-analysis was therefore performed to methodically incorporate and significantly evaluate randomized controlled ginger studies for the treatment of primary dysmenorrhea. The literature was searched using PubMed, Embase, Ovid, ClinicalKey, Medline, and electronic database. We have analyzed clinical trials by comparing ginger with placebo and non-steroidal anti-inflammatory drugs in women with primary dysmenorrhea. The primary outcomes assessed in our meta-analysis were pain severity and pain duration. Secondary outcomes were change in bleeding, side effects of the drug, and rate of satisfaction. We have screened a total of 638 studies, out of which narrative synthesis was formulated for eight studies. We have performed a meta-analysis of five trials examining ginger with placebo and other two randomized controlled trials comparing ginger with a non-steroidal anti-inflammatory drug (NSAID); it seems to be more helpful for relieving menstrual pain than a placebo (mean difference [MD] = 2.67, 95% CI = 3.51-1.84, P = 0.0001, I2 = 86%), although it was found that ginger and NSAIDs were equally effective in pain severity (risk ratios [RR] = 1.15, 95% CI = 0.53-2.52, P = 0.72, I2 =77%). We have not observed any significant difference between ginger and placebo on pain duration among primary dysmenorrheic women (MD = -2.22, 95% CI = -7.62-3.18, P = 0.42, I2 = 56%). Accessible information proposes that oral ginger can be a compelling treatment for primary dysmenorrhea. This meta-analysis strongly supports the requirement for high methodological quality consistency for upcoming trials.

The Relationship between Pain and Vascular Function Biomarkers in Dysmenorrheal University Students

Our aim was to establish if the secretion of contactin 1 (CNTN-1), a widely researched pain biomarker correlates with the severity of dysmenorrhea and circulating levels of vascular cell adhesion molecule 1 (VCAM-1) and angiotensin II (ANG-II). This study was a longitudinal randomized clinical study that involved 95 female students between 17–25 years. The control participant group were students who, without medications, had not experienced dysmenorrhea, while the inclusion criteria were primary dysmenorrhea without medications. Data was collected using demographic questionnaires that also contained the Numeric Rating Scale (NRS-11), while blood samples were collected for analysis of CNTN-1, VCAM-1 and ANG-II by ELISA. The participants' mean BMI's across the four pain strata were between 16.60–38.43 kg/m² and in addition to age and menarche, showed no correlation to either the NRS-11 scale (r=−0.01214) or their CNTN-1 levels (r=0.009622). The severe dysmenorrhea group showed statistically higher (p<0.0001) and positive correlation to systolic (r=0.7304) and diastolic (0.6588) blood pressures. The contactin 1 levels (7.00-55.70 ng/mL) increased with higher menstrual pain and as the pain increased, so did the mean VCAM-1 and ANG-II levels (p<0.0001). A positive linear correlation (r=0.9691) was observed between the NRS-11 scale of the participants and their CNTN-1 activities while the CNTN-1 levels positively correlated with their VCAM-1 (r=0.9334) and ANG-II (r=0.8746) secretion. In summary, the severity of dysmenorrheal pain elevates the contactin 1 levels which affects their vascular health and blood pressure.

Efficacy of herbal medicine (cinnamon/fennel/ginger) for primary dysmenorrhea: a systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

To assess the efficacy of herbal medicine (cinnamon/fennel/ginger) for treating primary dysmenorrhea.

METHODS

Relevant studies were searched in multiple databases. The weighted mean difference (WMD) was used as the effect indicator for measurement data, and each effect size was given estimates and 95% confidence intervals (CIs).

RESULTS

Nine studies with 647 patients were selected. Compared with the results in the control group, pain intensity was significantly relieved in the trial group when assessed by the intervention (cinnamon vs. placebo: WMD = 1.815, 95% CI = 1.330-2.301; fennel vs. placebo: WMD = 0.528, 95% CI = 0.119-6.829; ginger vs. placebo: WMD = 2.902, 95% CI = 2.039-3.765), observation period (one cycle: WMD = 2.061, 95% CI = 0.815-3.307; one cycles: WMD = 1.831, 95% CI = 0.973-2.690), and study quality (high quality: WMD = 2.224, 95% CI = 1.488-2.960). Pain duration was significantly shorter in the trial group (cinnamon vs. placebo: WMD = 16.200, 95% CI = 15.271-17.129). No publication bias was observed for either outcome.

CONCLUSIONS

For primary dysmenorrhea, cinnamon/fennel/ginger effectively reduced pain intensity, and cinnamon shortened the duration of pain. Further studies are needed to confirm our results.

Ginger and its bioactive component 6-shogaol mitigate lung inflammation in a murine asthma model

Asthma, a common disorder associated with airway inflammation and hyperresponsiveness, remains a significant clinical burden in need of novel therapeutic strategies. Patients are increasingly seeking complementary and alternative medicine approaches to control their symptoms, including the use of natural products. Ginger, a natural product that we previously demonstrated acutely relaxes airway smooth muscle (ASM), has long been reported to possess anti-inflammatory properties, although a precise mechanistic understanding is lacking. In these studies, we demonstrate that chronic administration of whole ginger extract or 6-shogaol, a bioactive component of ginger, mitigates in vivo house dust mite antigen-mediated lung inflammation in mice. We further show that this decrease in inflammation is associated with reduced in vivo airway responsiveness. Utilizing in vitro studies, we demonstrate that 6-shogaol augments cAMP concentrations in CD4 cells, consistent with phosphodiesterase inhibition, and limits the induction of nuclear factor-κB signaling and the production of proinflammatory cytokines in activated CD4 cells. Sustained elevations in cAMP concentration are well known to inhibit effector T cell function. Interestingly, regulatory T cells (Tregs) utilize cAMP as a mediator of their immunosuppressive effects, and we demonstrate here that 6-shogaol augments the Treg polarization of naïve CD4 cells in vitro. Taken together with previous reports, these studies suggest that ginger and 6-shogaol have the potential to combat asthma via two mechanisms: acute ASM relaxation and chronic inhibition of inflammation.

Ginger on Human Health: A Comprehensive Systematic Review of 109 Randomized Controlled Trials

Clinical applications of ginger with an expectation of clinical benefits are receiving significant attention. This systematic review aims to provide a comprehensive discussion in terms of the clinical effects of ginger in all reported areas. Following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guideline, randomized controlled trials on the effects of ginger were investigated. Accordingly, 109 eligible papers were fully extracted in terms of study design, population characteristics, evaluation systems, adverse effects, and main outcomes. The reporting quality of the included studies was assessed based on the Cochrane Collaboration's tool for assessing the risk of bias in randomized trials and integrated together with studies that investigated the same subjects. The included studies that examined the improvement of nausea and vomiting in pregnancy, inflammation, metabolic syndromes, digestive function, and colorectal cancer's markers were consistently supported, whereas other expected functions were relatively controversial. Nevertheless, only 43 clinical trials (39.4%) met the criterion of having a 'high quality of evidence.' In addition to the quality assessment result, small populations and unstandardized evaluation systems were the observed shortcomings in ginger clinical trials. Further studies with adequate designs are warranted to validate the reported clinical functions of ginger.
