The goal of this clinical trial is to find out whether a herbal medicine called STW 5-II can help improve gut health and symptoms in adults recently diagnosed with functional dyspepsia (FD)-a condition that causes frequent stomach discomfort, especially after eating.
The main questions it aims to answer are:
Can STW 5-II reduce certain immune cells (eosinophils) in the gut lining? Can it improve symptoms like severe postprandial fullness, bloating, epigastric pain, and improve quality of life?
Researchers will compare STW 5-II to a placebo to see if it helps reduce gut inflammation and ease symptoms.
Participants will:
Take either STW 5-II or a placebo for 8 weeks Provide small samples of gut tissue (via endoscopy) Answer questions about their symptoms and daily life An optional 4-week treatment with STW 5-II will follow for all participants.
