Ginger and Reduced Nausea and Vomiting

Research synthesisModerate evidenceModerate effect3 studies · 3 beneficial · 0 neutral · 0 harmful

Across 3 studies, all reported beneficial effects of ginger for reducing nausea and vomiting in pregnant women, with predominantly moderate effect sizes. The evidence is based on systematic reviews and a meta-analysis, but the small number of studies (only 3) limits confidence. Doses were inconsistently reported, with one study citing a range of 35–500 mg.

Studied populations: pregnant women

Caveats: Available evidence is overwhelmingly positive — clinical literature in this area is subject to publication bias (null-result studies are less likely to be published or indexed). Evidence base is small (only 3 studies) — conclusions should be considered preliminary. One included study (2025) had low methodological quality, and no consistent dose or form data were reported across studies.

Ginger was the most investigated remedy and was consistently reported to ameliorate nausea and vomiting during pregnancy better than placebo; its efficacy in doing so was noted to be equal to that of vitamin B6 and dimenhydrinate.
