1. Apply a small amount of white sugar to the surface of the mouth ulcer, 2–3 times a day. Dip a cotton swab in some Bingpengsan (Ice Borax Powder) and apply it to the affected area. Although it may taste a little bitter, the sore will heal after 2–3 days of consistent use.

 

2. Remove the outer skin of a garlic clove, take the thin transparent film that wraps the clove, and place it over the mouth ulcer. Dissolve a tablet of Huasu tablets (Cydiodine Buccal Tablets) in the mouth, 1–2 tablets at a time, 3–4 times a day.

 

3. After cleaning your mouth, use a cotton swab to apply honey to the ulcer. Avoid eating for the time being. After 15 minutes, you may swallow the honey and reapply. This can be repeated many times within 24 hours.

 

Note: Eating more tomatoes may also help with mouth ulcers.
