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.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Danning Tablet (Biliflow), an herbal medicine taken orally, combined with lifestyle management (diet and habits)
What this could lead to
If effective, Danning tablets could offer a non-surgical way to shrink or clear gallbladder polyps, potentially reducing the need for surgery.
What could go wrong
This is a phase 4 trial, but results are not yet known. The effect may be modest, and some people may not respond. Side effects are possible, though the medicine is already in use.
