Overview

Yu-Chuan-San is a topical traditional Chinese medicine (TCM) formulation developed by Beijing Shijitan Hospital Affiliated to Capital Medical University for the treatment of mild recurrent aphthous ulcers (canker sores). Formulated as a powder (indicated by the suffix 'San'), it is applied directly to the oral mucosa to provide rapid analgesia and promote the healing of ulcerated lesions. In clinical research, including a randomized controlled trial (ChiCTR2000038691), Yu-Chuan-San has been evaluated for its analgesic intensity, effective rate, and impact on ulcer area compared to established treatments like Tongrentang oral ulcer powder. As a multi-ingredient herbal preparation, its therapeutic effects are attributed to the synergistic anti-inflammatory and mucosal protective properties of its botanical components.
