Dr. Zhang Liwen
Pineapple is considered a “heaty” fruit in traditional Chinese medicine, and bromelain—an enzyme found in pineapple—can irritate the oral mucosa, potentially triggering mouth ulcers. Topical treatments for oral ulcers—such as ulcer ointments or ulcer powders—can help alleviate local pain and promote wound healing. In daily life, maintaining good oral hygiene, keeping the oral mucosa moist, and rinsing the mouth after meals are all important preventive measures.
