Is Feng You Jing effective for oral ulcers?

Fengyoujing cannot treat oral ulcers. Fengyoujing is effective for refreshing the mind and relieving insect bites, but it has no therapeutic effect on oral ulcers. It is an external-use medication; ingestion may cause irritation and potentially result in stinging pain at the ulcer site. For oral ulcers, it is recommended to use medications such as Cetylidine lozenges or Amoxicillin capsules under a physician’s guidance. Alcohol consumption should be avoided during treatment.
