Summary
That instinct to lick a small cut might not be random—your saliva contains natural healing proteins like histatin, EGF, and Trefoil Factor 3 that help skin cells repair faster. Studies show these compounds can speed up wound closure and even support new blood vessel growth, which is important for healing. In lab tests, wounds exposed to saliva-related compounds closed faster than untreated ones. Scientists are still exploring how powerful this natural “built-in repair system” really is.
