How to use Yike Tie for oral ulcers: which side should be applied?

1. Preparation: Ensure your hands are clean before use; wash them with soap and water and then dry thoroughly. 2. Removing the patch: Take the Yiketie patch out of the packaging, being careful not to touch the back side of the patch. 3. Cleaning the ulcer area: Keep the area around the oral ulcer as dry as possible. Rinse your mouth with tap water if needed, then gently dry by吸干水分 (absorbing excess moisture). 4. Applying the patch: Gently place the white side of the Yiketie patch directly onto the oral ulcer, ensuring complete coverage. Press lightly for 10–15 seconds to ensure full contact with the oral mucosa and secure adhesion to the ulcer surface. 5. Precautions: Yiketie is for external use only; do not swallow. Avoid spicy or irritating foods during use, as they may worsen ulcer pain. Discontinue use immediately and consult a doctor if you experience an allergic reaction. If the oral ulcer does not heal within a prolonged period or symptoms worsen, seek medical attention promptly.
