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.
