The cause of oral ulcer is low immunity, lack of vitamins and easy to get angry! In traditional Chinese medicine, there is a bubble on the tip of the tongue.

Suggestion:

I suggest that you can take vitamin C orally or soak in water in your daily life, and soak more honeysuckle and lotus plums, all of which are heat-clearing and detoxifying! Lotus seeds are venting their anger! You can eat more bitter gourd!
