Mouth ulcers so painful you can't eat? Tongrentang's "Little Blue Bottle" Oral Ulcer Powder is a household staple, a common "fire extinguisher." The fine blue powder penetrates deeply into ulcer crevices, providing instant cooling and comfort upon application, forming a protective layer over the wound and relieving the burning pain.

• 【Classic Formula】Contains natural indigo, alum, and borneol, targeting canker sores caused by "internal heat."
• 【Rapid Pain Relief】Borneol provides a cooling sensation, quickly alleviating the torment of redness, swelling, heat, and pain.
• 【Astringent Healing】Alum helps dry the ulcer surface, promoting scab formation and shortening the healing period.
• 【Deep Powder Penetration】Unlike patches, the fine powder can cover various hard-to-reach areas like the tongue tip, gums, and corners of the mouth.

Usage Scenarios: Suitable for oral ulcers, tongue blisters, angular cheilitis (cracked corners of the mouth), and gum swelling and pain caused by "internal heat."

Product Specifications: 3g * 10 bottles/box

Usage Tips: For external use. Apply with a cotton swab or spray directly onto the affected area. After application, please close your mouth for 1-2 minutes and avoid swallowing or drinking water to allow the powder to adhere fully. A temporary blue residue in the mouth after use is normal and can be cleaned by rinsing.
