Motion Sickness: Mechanisms and Ginger's Action
Kinetosis (ginger motion sickness) results from a conflict between vestibular (inner ear), visual, and proprioceptive information. Intestinal serotonin and H1 histaminergic receptors trigger nausea.
Ginger acts on:
- 5-HT3 Antagonism: blocks serotonin receptors on the vagus nerve that transmit the signal of bloating-remede-naturel-2026">nausea to the vomiting center (medulla)
- Mild H1 Antihistamine: same receptor as dimenhydrinate, but without sedation (peripheral, not central mechanism)
- Gastric Emptying Activation: accelerates ginger bloating-colon-irritable">gastric emptying by 12-15 min → reduction of nausea related to stasis
- Vestibular Anti-spasmodic: reduces vagal reflexes triggered by sensory conflicts
Clinical Studies: Ginger vs. Anti-Motion Sickness Medications
- Mowrey & Clayson 1982 (Lancet): first RCT — ginger 940mg > dimenhydrinate 100mg for kinetosis prevention on a rotating chair
- Schmid et al. 1994: ginger 1g pre-travel = dimenhydrinate 100mg — comparable efficacy, no drowsiness with ginger
- Grøntved et al. 1988: ginger reduced navigation-related nausea by 72% vs. placebo in a double-blind study
INTI Travel Protocol
Prevention (Before Departure)
- 30-60 min before: 20-30ml INTI pure (or diluted if sensitive stomach)
- Repeat 10-15ml every 4h during travel if necessary
During Travel (Nausea Triggered)
- 20ml INTI at the first symptoms — effect within 15-20 min
- Fix gaze on the horizon (sensory coherence)
- Avoid reading and screens in vehicles
Types of Transportation
- Car/bus: 20ml INTI 30 min before + 10ml/4h
- Boat: 30ml INTI 1h before + scopolamine patch if travel >6h in rough seas
- Plane: turbulence → 20ml INTI at departure + 10ml if turbulence

ginger dizziness Positional Vertigo (BPPV) and Ginger
Positional vertigo (BPPV — benign paroxysmal positional vertigo, related to otoliths) is different from kinetosis. Ginger is not a treatment for BPPV (the Epley maneuver remains the reference), but it can reduce associated nausea.
FAQ — Ginger and Motion Sickness
Why does ginger not cause drowsiness unlike antihistamines?
Dimenhydrinate acts centrally (crosses the BBB) → sedation. Ginger acts peripherally on intestinal H1 receptors and vagus nerve 5-HT3 receptors without significantly crossing the blood-brain barrier → no sedation.
Is INTI effective for motion sickness in children?
From 6 years old, 5-10ml INTI in apple juice is safe and effective. For children aged 3-6, consult your pediatrician before use.
Ginger for ginger and pregnancy-remede-naturel">ginger during pregnancy while traveling: doubly effective?
Yes — INTI is one of the rare remedies that simultaneously treats pregnancy nausea AND travel kinetosis. Particularly useful in the 1st trimester for pregnant women who travel.
INTI is a Belgian fresh cold-pressed organic ginger elixir in Belgium. This information is educational. Persistent or recurrent dizziness requires an ENT consultation.
