Question: I often accidentally bite my lips while brushing teeth or eating, which easily leads to oral ulcers. Whenever there’s a cut on the lip, an ulcer forms. What should be done?

Answer: You need to be careful when brushing your teeth, as repeated occurrences of oral ulcers can trigger an allergic reaction, leading to stubborn oral ulcers that may even develop into systemic autoimmune diseases. If you already have an ulcer, it is recommended to apply Bingpeng Powder locally.
