First seen Jul 20, 2026 · Last updated Jul 21, 2026 · Updated 1 time

Summary

This study tests whether a traditional Chinese herbal formula called Hewei Anchang Formula can ease overlapping symptoms of functional dyspepsia (indigestion) and diarrhea-predominant irritable bowel syndrome (IBS-D). Researchers will give 120 adults either the herbal granules or a placebo for 4 weeks and track symptom changes. The goal is to see if one treatment can address both conditions at once, based on the idea that they share an underlying imbalance.
