Can a herbal formula restore hearing? new trial investigates
NCT ID NCT07505667
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether Yiyuancong, a traditional Chinese medicine made from food-like ingredients, can help people with sudden hearing loss. About 128 adults aged 18-60 will take the formula for 1-2 months, and their hearing will be measured with standard tests. The goal is to see if it improves hearing better than usual care alone.
