NCT ID NCT07761013
First seen Aug 12, 2026 · Last updated Aug 13, 2026 · Updated 1 time
Summary
This trial tests whether Yanlishuang buccal dropping pills, a traditional Miao medicine, can relieve the sore throat and pain of acute pharyngitis. About 400 adults with a sore throat that started within the last 48 hours will be randomly assigned to take either the herbal drops or a placebo for up to 5 days. The main goal is to see how quickly the sore throat completely resolves, with secondary measures looking at immediate pain relief and other symptoms.
