Ginger and Nausea: The #1 Natural Remedy Proven by 20+ Studies
Motion sickness, morning sickness, post-operative or chemotherapy-related nausea? Ginger is the most studied natural remedy for nausea — with over 20 clinical trials to its credit. Here's everything you need to know.
Why ginger is so effective against nausea
Gingerol and shogaol act on 5-HT3 serotonin receptors — exactly the same receptors targeted by ondansetron (Zofran), the reference anti-nausea medication. In addition:
- Prokinetic action: ginger accelerates gastric emptying by 25-50%, reducing gastric stasis that causes nausea
- Central and peripheral action: it acts on both the vomiting center in the brain and gastrointestinal receptors
- Digestive anti-inflammatory-guide-complet-gingembre-turmeric-2026">: reduces mucosal inflammation that amplifies nausea
