Using Fengyoujing for Oral Ulcers

It is not recommended to use Fengyoujing (a traditional Chinese topical remedy) for oral ulcers. Although Fengyoujing can help refresh the mind and relieve pain caused by insect bites, it is ineffective for treating oral ulcers. As a topical medication, Fengyoujing is not intended for internal use; applying it directly to oral ulcers may cause stinging or other discomfort at the affected site. Self-medication without professional guidance is strongly discouraged. Instead, consult a physician for appropriate treatment—such as using Xiguashuang spray—and maintain a diet rich in fruits.
