What should I do for mouth ulcers and chapped lips?
Generally speaking, oral ulcers are often associated with deficiencies in vitamins such as B₂, B₆, and B₁₂. Patients are advised to regularly consume fresh vegetables and fruits rich in these vitamins—such as carrots and kiwifruit. Additionally, deficiencies in iron or folic acid may also trigger oral ulcers. So, what should be done when oral ulcers are accompanied by chapped lips? The following section addresses this question.

What to Do for Oral Ulcers Accompanied by Chapped Lips
In most cases, for patients with oral ulcers who also experience chapped lips, mouthwash can be used effectively. Moreover, the mouthwash should be held in the mouth for a longer duration than usual—extending the rinsing time from the typical 10 minutes to approximately 15 minutes. Recommended mouthwashes include Kangfuxin (Periplaneta americana extract) mouthwash, compound boric acid solution mouthwash, ethacridine lactate (Rivanol) mouthwash, or chlortetracycline solution mouthwash—all of which help promote healing of oral ulcers.
These mouthwashes can also alleviate chapped lips, making them highly suitable for such cases. If oral ulcers co-occur with chapped lips, patients should also increase their intake of fresh vegetables and fruits rich in vitamins B₁, B₂, B₆, and B₁₂ to support recovery.
Furthermore, maintaining a positive mood, abstaining from smoking and alcohol, avoiding excessive fatigue and stress, and adopting appropriate lifestyle adjustments are all essential for achieving complete resolution.
