Herbal bath may help anal surgery wounds heal faster
NCT ID NCT07562672
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a daily bath with a traditional Chinese herbal mixture called Tongyangxiao can help surgical wounds heal faster after anal fistula surgery. 115 patients used either the herbal bath or a standard antiseptic bath for 14 days after surgery. Researchers measured wound closure time, pain, and inflammation to see if the herbs made a difference.
