Mouth ulcers are generally caused by various factors related to the patient, such as local trauma, certain foods, frequent use of certain medications, poor nutrition, changes in hormone levels in the body, and excessive mental stress. Additionally, a deficiency in vitamins or trace elements in the body, or some systemic diseases, can also lead to the occurrence of mouth ulcers.

When patients experience mouth ulcers, they can appropriately consume some Dendrobium, as it is beneficial for ulcers and is edible. However, it is recommended that patients with mouth ulcers still undergo local ulcer treatment. They can use specific medications for mouth ulcers, such as mouth ulcer lozenges or xyliodine lozenges, which can be directly applied to the ulcerated surface and can aid significantly in healing.

Additionally, it is suggested that patients frequently use Kangfuxin Liquid for oral rinsing, which can effectively control bacterial infection in the mouth. Regarding diet, it is important to eat lightly and diversely, including plenty of fresh vegetables and fruits to adequately supplement nutrients.

(The use of medications should be under the guidance of a physician.)
