What should you do for mouth sores caused by excessive internal heat?

The following measures can help relieve mouth sores or oral inflammation (commonly referred to as "mouth heatiness"): 1. Dietary adjustment: Eat more light, cooling foods such as bitter gourd, winter melon, cucumber, and fruits like pears and watermelon. Avoid spicy, greasy, and irritating foods, and reduce sugar intake to lower the risk of oral inflammation. 2. Lifestyle care: Maintain healthy habits by avoiding late nights and ensuring sufficient sleep to boost immune function. Also, maintain a positive mood and avoid excessive stress and anxiety. 3. Medication: If symptoms are severe, take traditional Chinese medicines with heat-clearing and detoxifying effects—such as Niuhuang Jiedu Pian (Bezoar Detoxification Tablets) or Sanhuang Pian (Three Yellow Pills)—under a doctor's guidance. Topical treatments like Bingboran Powder or Watermelon Frost spray, which have anti-inflammatory, pain-relieving, and detoxifying properties, may also be used. With proper dietary adjustments, lifestyle care, and medication, symptoms of oral inflammation can usually be effectively relieved. However, if symptoms worsen or persist, prompt medical consultation is recommended.
