How Safe Is Ginger Rhizome for Decreasing Nausea and Vomiting in Women during Early Pregnancy?

ABSTRACT: Ginger, Zingiber officinale Roscoe, is increasingly consumed as a food or in food supplements. It is also recognized as a popular nonpharmacological treatment for nausea and vomiting of pregnancy (NVP). However, its consumption is not recommended by all countries for pregnant women. Study results are heterogeneous and conclusions are not persuasive enough to permit heath care professionals to recommend ginger safely. Some drugs are also contraindicated, leaving pregnant women with NVP with few solutions. We conducted a review to assess effectiveness and safety of ginger consumption during early pregnancy. Systematic literature searches were conducted on Medline (via Pubmed) until the end of December 2017. For the evaluation of efficacy, only double-blind, randomized, controlled trials were included. For the evaluation of the safety, controlled, uncontrolled, and pre-clinical studies were included in the review. Concerning toxicity, none can be extrapolated to humans from in vitro results. In vivo studies do not identify any major toxicities. Concerning efficacy and safety, a total of 15 studies and 3 prospective clinical studies have been studied. For 1 g of fresh ginger root per day for four days, results show a significant decrease in nausea and vomiting and no risk for the mother or her future baby. The available evidence suggests that ginger is a safe and effective treatment for NVP. However, beyond the ginger quantity needed to be effective, ginger quality is important from the perspective of safety.

Project description:BackgroundNausea and vomiting of pregnancy (NVP) affect approximately 80-90% of the pregnant women. Ginger (Zingiber officinale Roscoe) is the most widely used herbal therapy in the management of NVP. Like conventional therapies, herbal therapies have potential harms and benefits that patients need to be informed about in order to develop their therapy preferences. The aim of this study was to achieve consensus among women who suffered NVP and physicians often consulted by pregnant women on a core list of potential harms and benefits of using ginger to manage NVP to be addressed during clinical consultations.MethodsIn this study, the Delphi technique was used to achieve consensus on a core list of important harms and benefits of using ginger in the management of NVP to be addressed during the clinical consultation. A Delphi process was followed in two panels in parallel sessions. One panel was composed of 50 gynecologists and other physicians who are often consulted by pregnant women suffering NVP and the other panel was composed of 50 women who suffered NVP.ResultsConsensus was achieved on 21 (75%) of the 28 potential harms presented to the panelists. Panelists agreed that potential harms of the anticoagulant effects of ginger, risk with other co-morbidities, and risk of potential allergic reactions are important to address during the clinical consultation. Of the 14 potential benefits presented to the panelists in both panels, consensus was achieved on 13 (92.9%). Partial consensus on 7 potential harms and 1 potential benefit was achieved in both panels.ConclusionsAddressing important potential harms and benefits of using ginger for the management of NVP during the clinical consultations is important in promoting congruence and reducing patient dissatisfaction in clinical practice. Consensus was achieved on a core list of important harms and benefits of using ginger for the management of NVP to be addressed during the clinical consultations by a panel of women and a panel of physicians. Further studies are still needed to investigate what is being addressed during clinical consultations.

Project description:Importance:Nausea and vomiting during pregnancy have been associated with a reduced risk for pregnancy loss. However, most prior studies enrolled women with clinically recognized pregnancies, thereby missing early losses. Objective:To examine the association of nausea and vomiting during pregnancy with pregnancy loss. Design, Setting, and Participants:A randomized clinical trial, Effects of Aspirin in Gestation and Reproduction, enrolled women with 1 or 2 prior pregnancy losses at 4 US clinical centers from June 15, 2007, to July 15, 2011. This secondary analysis was limited to women with a pregnancy confirmed by positive results of a human chorionic gonadotropin (hCG) test. Nausea symptoms were ascertained from daily preconception and pregnancy diaries for gestational weeks 2 to 8. From weeks 12 to 36, participants completed monthly questionnaires summarizing symptoms for the preceding 4 weeks. A week-level variable included nausea only, nausea with vomiting, or neither. Main Outcomes and Measures:Peri-implantation (hCG-detected pregnancy without ultrasonographic evidence) and clinically recognized pregnancy losses. Results:A total of 797 women (mean [SD] age, 28.7 [4.6] years) had an hCG-confirmed pregnancy. Of these, 188 pregnancies (23.6%) ended in loss. At gestational week 2, 73 of 409 women (17.8%) reported nausea without vomiting and 11 of 409 women (2.7%), nausea with vomiting. By week 8, the proportions increased to 254 of 443 women (57.3%) and 118 of 443 women (26.6%), respectively. Hazard ratios (HRs) for nausea (0.50; 95% CI, 0.32-0.80) and nausea with vomiting (0.25; 95% CI, 0.12-0.51) were inversely associated with pregnancy loss. The associations of nausea (HR, 0.59; 95% CI, 0.29-1.20) and nausea with vomiting (HR, 0.51; 95% CI, 0.11-2.25) were similar for peri-implantation losses but were not statistically significant. Nausea (HR, 0.44; 95% CI, 0.26-0.74) and nausea with vomiting (HR, 0.20; 95% CI, 0.09-0.44) were associated with a reduced risk for clinical pregnancy loss. Conclusions and Relevance:Among women with 1 or 2 prior pregnancy losses, nausea and vomiting were common very early in pregnancy and were associated with a reduced risk for pregnancy loss. These findings overcome prior analytic and design limitations and represent the most definitive data available to date indicating the protective association of nausea and vomiting in early pregnancy and the risk for pregnancy loss.
