First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a herbal medicine called STW 5-II can reduce inflammation in the gut lining and ease symptoms like stomach pain, bloating, and fullness after eating in people with functional dyspepsia. About 100 adults will take either the herbal remedy or a placebo for 8 weeks, with tissue samples and symptom diaries used to measure effects. An optional 4-week treatment extension is available for all participants.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
STW 5-II (a blend of six herbal extracts: bitter candy tuft, chamomile, caraway, melissa, peppermint, and licorice root)
What this could lead to
If successful, this could point toward a natural, well-tolerated option for managing functional dyspepsia symptoms and reducing gut inflammation.
What could go wrong
This is a small, early proof-of-concept trial. The herbal mixture may not outperform placebo, and results may not apply to all patients. Side effects are possible but typically mild.
