NCT ID NCT05668871
First seen Aug 05, 2026 · Last updated Aug 06, 2026 · Updated 1 time
Summary
This trial tests whether Danning tablets, an herbal medicine, can reduce the size or clear multiple gallbladder polyps when combined with lifestyle changes like a low-fat diet and avoiding alcohol. Adults aged 18-75 with polyps between 3-7 mm are enrolled. The main goal is to see if the treatment improves symptoms and shrinks polyps after 24 weeks, compared to lifestyle changes alone.
