Herbal granules aim to ease Post-Meal stomach troubles
NCT ID NCT06696261
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This Phase 3 trial tests whether Lianxiaxiaopi Granules, a traditional Chinese herbal medicine, can relieve symptoms of postprandial distress syndrome (stomach discomfort, fullness, or early fullness after meals). 342 adults aged 18-65 will take the granules or a placebo three times daily for 8 weeks. The study measures how many weeks symptoms improve by at least half compared to baseline.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Lianxiaxiaopi Granules (herbal granules)
- What this could lead to
- If successful, this could provide a new herbal treatment option for people with postprandial distress syndrome, reducing discomfort after meals.
- What could go wrong
- This is a Phase 3 trial, but the intervention is based on Traditional Chinese Medicine concepts (cold/heat imbalance) which may not be accepted by all. The placebo response in digestive disorders can be high, so the real benefit may be modest.
