Mouth ulcers during breastfeeding can be treated with watermelon cream for spraying the ulcerated surface. Watermelon cream has little effect on the body and can be used on women who are breastfeeding. If mouth ulcers occur during breastfeeding, don’t worry, mouth ulcers are just ulcerative diseases on the oral mucosa and do not affect breastfeeding. Mouth ulcers themselves are a self-limiting disease and can heal on their own in half a month or so even if no treatment is taken. If the pain of mouth ulcers is obvious during breastfeeding, you can spray watermelon cream locally. Watermelon cream is a proprietary Chinese medicine with anti-inflammatory and analgesic effects, with little side effects and safety. Watermelon Cream has no obvious effect on breastfeeding women and babies. It will not enter the body with blood and saliva and be secreted into breast milk, which will have an adverse effect on children. Breastfeeding mouth ulcers are recommended to drink more water, eat a reasonable diet, eat more vegetables and fruits, and keep a relaxed mood, which will help the condition to recover. The use of drugs should be used under the guidance of a physician.
