Developing recurrent oral ulcers during menstruation may result from a temporary decline in immune function or from frequent consumption of spicy foods (e.g., chili peppers), which can damage the oral mucosa. Treatment typically involves symptomatic management—such as using medications like “Xigua Shuang” (Watermelon Frost) spray—under a physician’s guidance. In daily life, it is advisable to consume bland, easily digestible foods.
