There are many things that are contraindicated for mouth ulcers, such as the following:
1. chewing gum, chocolate, hot food and spicy barbecue.
2. Irritating condiments such as vinegar, ginger, scallions and star anise. These condiments can induce pain and also irritate the ulcer surface, prompting it to expand.
3. Rough and hard foods such as fried ribs, fried chicken legs and other foods. These hard foods can rub against the ulcer surface and aggravate the condition.
4. things after grinding, because these things will stay on the surface of the ulcer, slowing down the recovery of mouth ulcers.
It is recommended that patients with mouth ulcers should take some lighter foods in their normal life.
