Last updated: June 2026 · Reviewed by the FactoWiki Editorial Team for clarity and source accuracy
Quick summary
Ginger is a culinary root with genuinely good evidence for one thing in particular: easing nausea, including in pregnancy, motion sickness and after surgery. Its anti-inflammatory and joint claims are more modest.
What is Ginger?
Ginger (Zingiber officinale) is the rhizome of a flowering plant used worldwide as both a spice and a traditional remedy, especially for digestion and nausea. Its active compounds are gingerols and shogaols. It is taken as fresh root, dried powder, capsules, teas and crystallised forms, and appears in digestive and anti-nausea products. Among herbal remedies, ginger stands out for having a clear, well-supported primary use.
What Ginger is commonly used for
Ginger is used in supplements as nutritional support, not as a treatment for any medical condition.
How Ginger works
Ginger's compounds act on the digestive tract, speeding stomach emptying and influencing serotonin receptors in the gut that are involved in the nausea-and-vomiting reflex — a similar target to some anti-nausea drugs. This is the basis for its well-established anti-nausea effect. Gingerols also have mild anti-inflammatory activity, which underlies its weaker joint and general anti-inflammatory claims.
What the evidence says
Here's an honest snapshot of what published research suggests about Ginger — including where the evidence is limited.
- Multiple trials and reviews support ginger for reducing nausea — including pregnancy-related nausea, motion sickness, and post-operative and chemotherapy-related nausea, though the size of effect varies. (PubMed research)
- Some studies suggest modest reductions in osteoarthritis pain and markers of inflammation, but the effect is smaller and less consistent than for nausea. (PubMed research)
- Effects on blood sugar and cholesterol have been explored with preliminary, mixed results. (PubMed research)
Typical dosage used in studies
For nausea, trials commonly use up to about 1-1.5 g/day of dried ginger, split into doses. Culinary amounts are smaller. This is research information, not a recommendation.
Side effects and safety
Ginger is generally very safe, especially in food amounts. Higher supplement doses can cause heartburn, mild stomach upset or a burning sensation. At high doses it may have a mild blood-thinning effect.
Medication interactions and who should avoid Ginger
Medication & safety check
People on blood thinners or facing surgery should be cautious with high-dose ginger supplements. Those with gallstones should check with a doctor, as ginger increases bile flow. In pregnancy, moderate amounts are widely used for nausea, but it is sensible to confirm the amount with a healthcare provider, particularly close to delivery.
This is general information, not personal medical advice. If you take any medication, confirm it's safe to combine with Ginger with your doctor or pharmacist first.

Frequently asked questions
What is ginger best for?
Nausea — it has solid evidence for pregnancy-related nausea, motion sickness, and post-surgery and chemotherapy nausea. That's its standout, well-supported use.
Does ginger help joint pain or inflammation?
There's modest, less consistent evidence for easing osteoarthritis pain. The effect is smaller than for nausea.
How much ginger for nausea?
Trials often use up to about 1-1.5 g/day of dried ginger in divided doses.
Is ginger safe in pregnancy?
Moderate amounts are widely used for morning sickness, but confirm the amount with your provider, especially near term.
Are there side effects?
Mostly mild — heartburn or stomach upset at higher doses, and a mild blood-thinning effect that matters if you take blood thinners or have surgery coming up.
