Ginger for nausea: what the evidence actually shows

If there's one health benefit of ginger that's virtually undisputed, it's its anti-nausea effect. The evidence is remarkably strong.

Pregnancy nausea

A Cochrane review (the gold standard of evidence-based medicine) found ginger significantly reduces nausea and vomiting in early pregnancy. The WHO and ACOG both recommend it as a first-line treatment.

Motion sickness

Multiple studies show ginger reduces motion sickness symptoms comparably to dimenhydrinate (Dramamine), without the drowsiness side effect.

Chemotherapy-induced nausea

A 2012 trial published in the Journal of Clinical Oncology found that ginger supplementation (0.5-1g/day) reduced chemotherapy-induced nausea by 40% when combined with standard anti-emetics.

The mechanism

Ginger acts on 5-HT3 receptors in the gut — the same receptors targeted by ondansetron (Zofran), one of the most commonly prescribed anti-nausea drugs.

Sugar and nausea

High sugar intake can actually worsen nausea by causing rapid blood sugar fluctuations. A ginger product with 34g sugar/100ml may paradoxically increase nausea rather than reduce it.

For maximum anti-nausea benefit without sugar: INTI — triple formula, zero added sugar, organic.
