I understand pouring alcohol on a wound can help prevent it from becoming infected. It doesn’t matter whether it’s bourbon or gin, vodka or scotch; it may hurt at first, but the pain will subside. If the problem is a bruised ankle, stay off of it for awhile.
If the wound is internal, mixing the alcohol with something like vermouth or tonic, along with some ice, may help. The alcohol may not heal the wound any faster, but it helps deaden the pain.
