Ginger

What does the research say about Ginger?

5 health outcomes synthesised

Ginger has been studied across 5 health outcomes, with the strongest evidence supporting its use for reducing vomiting frequency. Three studies involving pregnant women, including those with hyperemesis gravidarum, and chemotherapy patients found predominantly large effects at approximately 1 g/day. The evidence for improving insulin sensitivity and reducing nausea and vomiting in pregnant women is also promising but based on small study bases.

Strongest evidence: Ginger shows moderate evidence for reducing vomiting frequency (3 studies, large effect) and reducing nausea and vomiting in pregnant women (3 studies, moderate effect). For vomiting, the typical dose was approximately 1 g/day for at least 4 days.

Mixed or weaker evidence: Ginger has low evidence for improving insulin sensitivity (3 studies, small effect) and mixed findings for reducing hemoglobin A1c (1 beneficial, 2 neutral) and pain intensity (1 beneficial, 2 neutral). The small number of studies and inconsistent results limit confidence in these areas.

Effective dose patterns: A consistent effective dose emerged only for vomiting frequency (~1 g/day). Other outcomes lacked consistent dose data, making cross-outcome dose comparisons difficult.

Population insights: Pregnant women (including those with hyperemesis gravidarum) and chemotherapy patients were the most studied populations for nausea and vomiting. Insulin sensitivity benefits were observed in individuals with type 2 diabetes, MASLD, and PCOS.

Notable caveats: Publication bias is a concern across all positive outcomes, as null-result studies may be underreported. All evidence bases are small (3 studies each), warranting cautious interpretation. Doses and forms were inconsistently reported across studies.

Frequently asked

  • What is Ginger good for according to research?
    Research indicates ginger is most effective for reducing vomiting frequency (3 studies, moderate evidence, large effect) and reducing nausea and vomiting in pregnant women (3 studies, moderate evidence). It also shows some benefit for improving insulin sensitivity (3 studies, low evidence).
  • What dose of Ginger is typically used in studies?
    A consistent dose is reported only for reducing vomiting frequency, at approximately 1 g/day for at least 4 days. Doses for other outcomes were inconsistently reported or ranged widely (e.g., 35–500 mg for nausea in pregnancy).
  • Who benefits most from Ginger?
    Pregnant women, including those with hyperemesis gravidarum, and patients undergoing chemotherapy benefit most for nausea and vomiting. For insulin sensitivity, benefits were seen in individuals with type 2 diabetes, MASLD, and PCOS.
  • Are there caveats or limitations in the research on Ginger?
    Yes. All evidence bases are small (3 studies per outcome), and publication bias may inflate reported benefits. Doses and forms of ginger were inconsistently reported across studies, limiting practical conclusions.
  • Does Ginger help reduce pain intensity?
    The evidence is mixed. One study found a large benefit for primary dysmenorrhea, but two studies (including a larger meta-analysis) found no benefit, resulting in low evidence strength overall.
  • Can Ginger improve insulin sensitivity?
    All 3 studies reported small improvements in insulin sensitivity, though confidence is limited by low evidence strength and inconsistent dosing. Beneficial effects were noted in type 2 diabetes and PCOS populations.
