Does ginger help period pain?
Yes — in women with ordinary period pain, about 1.5 g of ginger powder a day around the period reduced pain versus placebo, and worked roughly as well as common painkillers in pooled trials. It's a whole-spice amount, and the effect is real but modest.
What the evidence supports
What it doesn't mean
- ✗ A cure — it eases pain, and the benefit sits near the clinically meaningful threshold
- ✗ Proof for pain duration in every schedule — that result was mixed
- ✗ A substitute for medical care in severe or worsening pain (e.g. endometriosis)
Where this comes from
- What the human evidence shows
- In a placebo-controlled trial of about 100 women with moderate-to-severe primary dysmenorrhea, 500 mg of ginger powder three times a day around the period reduced pain severity versus placebo (P = 0.015 and 0.029 across two schedules), and reduced pain duration when started before the period began.1 A 2021 systematic review pooled eight trials — every one using ginger powder, not an extract — and found ginger clearly beat placebo for pain severity and was statistically no different from NSAID painkillers.2
- How big is the effect, honestly
- Modest, and worth stating plainly. The trials were small, varied a lot between studies, and the average reduction in pain sits close to the change usually considered clinically meaningful rather than comfortably above it. The benefit for pain duration was less consistent than for severity. So the direction is reliable and reproducible, but this is a gentle help, not a dramatic one.
- Where the evidence stops
- This applies to primary dysmenorrhea — pain caused by the period itself. It says nothing about pain from underlying conditions such as endometriosis or fibroids, which need medical assessment. The dose that was tested is a plain-spice amount (~1.5 g/day of dried ginger, taken as capsules in the studies); we recommend no ginger supplement or extract, and if you take blood-thinning medication or are pregnant, check with a clinician first.
The practical version: if you get ordinary period cramps, ginger is a reasonable, low-cost thing to try — around three-quarters of a teaspoon of ground ginger a day (or 500 mg capsules three times daily), started as your period begins or a day before. It's roughly on a par with painkillers and gentle to combine with them. It is not a fix for severe or worsening pain, which is worth getting checked. We recommend no supplement, and we sell nothing.

Bottom line for you
For ordinary period pain, ginger genuinely helps: around 1.5 g of ginger powder a day — roughly three-quarters of a teaspoon of the ground spice — taken as your period starts eased pain about as well as standard painkillers in the trials. It's cheap, food-based, and reasonable to try, on its own or alongside your usual painkiller.
Keep expectations realistic. The effect is modest and the studies are small, so think of ginger as a gentle helper, not a cure. And it only speaks to normal period pain — pain that is severe, new or worsening deserves a proper check for causes like endometriosis. We recommend no ginger supplement, and we sell nothing.
