Does drinking Wanglaoji for mouth ulcers work?

Drinking Wanglaoji for mouth ulcers has no effect.
Wanglaoji is a kind of herbal tea with Chinese medicine ingredients, including chrysanthemum, honeysuckle, licorice, cactus, Xiaku Cao, etc. Such drugs have the effect of cooling the blood and detoxifying the toxin, clearing away heat and promoting dampness, but Wanglaoji herbal tea as a foodstuff is usually ineffective in drinking Wanglaoji for canker ulcers.
Mouth ulcers are usually self-limiting diseases, which can be relieved by maintaining oral hygiene, eating more vitamin-rich vegetables and fruits, reducing spicy and stimulating foods, strengthening physical exercise to enhance physical fitness, etc. Drugs to promote ulcer healing (e.g., oral ulcer powder) and anti-inflammatory drugs (e.g., cedirizumab) can also be chosen.
When mouth ulcers occur, it is recommended to consult a doctor in a timely manner and under the doctor’s guidance to carry out regular treatment. In addition, the above medications should also be used under medical supervision.
