Does ginger help with period cramps or stomach cramps?
This page covers period cramps (primary dysmenorrhea) and stomach or digestive cramps, what the underlying searches are actually about — not exercise-related muscle cramps, which no trial has tested ginger for. Several trials and reviews on menstrual pain generally favor ginger over placebo; stomach cramps specifically haven't been studied.
This page covers period cramps (primary dysmenorrhea) and stomach or digestive cramps, since that's what the searches behind it are actually asking about — not exercise-related or nighttime leg muscle cramps, which no trial has tested ginger for. Several trials on menstrual pain generally favor ginger over placebo; stomach cramps specifically haven't been studied at all.
What the evidence doesn't support
It doesn't support "cure" as the right word for any of this — the trials below measured a reduction in pain scores, not a resolution of the underlying cause of cramping. It doesn't support ginger for exercise-induced or nighttime leg muscle cramps, since no trial we found tested that. And it doesn't support treating menstrual-pain research as evidence for general stomach cramps — they're different symptoms with different research bases, and only one of the two has real trial data behind it.
What the trials found
Period cramps. This is ginger's best-studied use among the topics on this page. A 2016 Cochrane review pooled 3 small trials (266 women) and found ginger reduced pain scores versus placebo, though it rated the overall evidence low quality, mainly because of small sample sizes. A larger 2024 meta-analysis, pooling 12 trials, found ginger reduced both pain intensity and pain duration versus placebo; some of the pooled trials also compared ginger against NSAIDs or against exercise as separate arms. A newer 2026 trial in 96 women tested a standardized ginger extract twice daily across three menstrual cycles and found meaningfully lower pain and symptom-burden scores than placebo by the third cycle — that trial was funded by the extract's manufacturer, worth knowing when weighing the size of the effect. Doses and forms varied a lot across all these trials, from loose powder taken during the first few days of a cycle to a standardized twice-daily extract taken for three full months, so there's no single dose that all of this research points to.
Stomach or digestive cramps. This is a different, much less studied question. A review of ginger and digestive conditions found ginger's best-supported effect is on nausea; for other digestive symptoms, including general abdominal pain or cramping, the review found too few trials to draw a real conclusion. We found no dedicated trial testing ginger against stomach cramps, IBS-related cramping, or gas pain specifically.
| Source | Topic | Population/size | Finding |
|---|---|---|---|
| 2016 Cochrane review | Period cramps | 3 trials, 266 women | Reduced pain vs placebo; low-quality evidence |
| 2024 meta-analysis | Period cramps | 12 trials | Reduced pain intensity and duration vs placebo |
| 2026 RCT | Period cramps | 96 women, 3 cycles | Lower pain and symptom-burden scores vs placebo |
| 2019 review | Digestive conditions generally | Multiple trials, various conditions | Best-supported effect is nausea; too few trials for cramping specifically |
Questions people ask
Will ginger cure period cramps?
"Cure" isn't accurate. Several trials found ginger reduced pain scores compared with placebo, but the effect was a reduction, not a resolution of the cause, and the overall evidence has been rated low quality by the most rigorous review of the group.
Is ginger good for stomach cramps?
We found no trial testing that question directly. Ginger's best-supported digestive effect is on nausea, not cramping specifically — see ginger and digestive conditions for what that research covers.
Does ginger tea help with stomach cramps?
No trial we found tested ginger tea for stomach cramps specifically.
What dose of ginger was used for period cramps?
The trials varied: some used ginger powder in the 750-2,000 mg/day range during the first 3-4 days of a cycle, while the newer 2026 trial used a standardized extract taken twice daily for a full 90 days across three cycles. Those are different regimens, not one agreed-on dose.
When to talk to a doctor
Severe menstrual pain that isn't manageable, or that's getting worse, is worth discussing with a doctor — it can sometimes point to an underlying condition rather than typical primary dysmenorrhea. Persistent stomach cramps, especially with other symptoms like fever, vomiting, or blood, need medical evaluation rather than a supplement. Ginger is not a treatment for either.

- Efficacy of a Standardized Ginger Extract for Menstrual Pain and Associated Symptoms in Women With Primary Dysmenorrhea: A Randomized, Double-Blind, Placebo-Controlled Trial A 96-woman, 90-day randomized trial found a standardized ginger extract, taken twice daily across three menstrual cycles, reduced pain severity and overall dysmenorrhea severity significantly more than placebo; the study was funded by the extract's manufacturer.
