Seasickness and mechanism of action of ginger

Seasickness results from a conflict of signals between the inner ear (vestibule), eyes and proprioceptors. Ginger acts peripherally (digestive tract) rather than centrally:

• Blockage of 5-HT3 receptors in the tract ginger gastroenteritis-intestinal → ↓ peripheral nausea signal
• Acceleration of gastric emptying → ↓ accumulation of gastric fluid which amplifies the bloating-natural-remedy-2026">nausea
• Reduced dysrhythmic gastric contractility (main cause of seasickness)
