First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a daily herbal capsule called Nimsai Herbal can shrink hemorrhoids and reduce symptoms like pain and itching. Fifty adults with grade 2-3 hemorrhoids will take either the herbal blend or a placebo for 10 days. The main goal is to see if the hemorrhoids improve or if symptoms drop by at least 75%.
