Tongue is the fastest healing part of human body


Oral mucosa heals faster than skin, suggesting that saliva may have properties that aid wound healing. Saliva contains many compounds that are antibacterial or promote healing.

On the other hand, the cornea is the only part of a human body that has no blood supply; it gets oxygen directly through the air. The cornea is the fastest healing tissue in the human body, Most corneal abrasions will heal within 24-36 hours.
