Ginger and digestion: how it speeds up gastric emptying by 25%
Digestive problems (bloating, heaviness, reflux) affect 1 in 4 people in Europe. Ginger is a documented natural prokinetic that accelerates gastric transit without the side effects of medication.
The key study
Wu et al. (European Journal of Gastroenterology & Hepatology, 2008) conducted a randomized clinical trial:
- Result: ginger accelerates gastric emptying by +25%
- Dose: 1.2g of ginger powder
- Mechanism: stimulation of antral contractions (lower part of the stomach)
- Effect: significant reduction in bloating and feelings of fullness
Why digestion slows down
Functional gastroparesis (slow gastric emptying) is caused by:
- Meals rich in fats (slow down emptying by 50%)
- Chronic stress (activation of the sympathetic nervous system)
- Sedentary lifestyle (reduces peristalsis)
- Certain medications (opioids, anticholinergics)
Ginger vs. prokinetic drugs
| Agent | Mechanism | Efficacy | Side effects |
|---|---|---|---|
| Ginger | Antral stimulation + 5-HT | +25% emptying | Minimal |
| Metoclopramide | D2 antagonist + 5-HT4 | +30-40% emptying | Dyskinesia, drowsiness |
| Domperidone | D2 antagonist | +20-30% emptying | Cardiac risk |
| Erythromycin | Motilin agonist | +40-50% emptying | Antibiotic resistance |
Ginger offers a significant prokinetic effect without the neurological or cardiac side effects of medications.
Optimal digestive protocol
- Before meals: 15ml of ginger concentrate in a little water, 15-30 min before the meal
- After a heavy meal: 15ml in hot water (immediate prokinetic effect)
- As a course: 15-20ml/day for 21 days for a lasting effect on gastric motility
Adding turmeric for digestion
Curcumin stimulates bile production (+62%, Rasyid et al., 1999), essential for fat digestion. The combination of ginger (prokinetic) + turmeric (cholagogue) covers both aspects of digestion: motility and fat emulsification.
In practice
Essence d'INTI combines organic ginger (prokinetic +25%) + organic turmeric (cholagogue +62%) + organic black pepper. A shot before the meal = easier digestion. 1.1g natural sugar/100ml.
