Lick your wounds
Ever wondered why mouth ulcers clear up in days but a shaving cut takes weeks to heal? Scientists from the Federation of American Societies for Experimental Biology found human spit heals wounds super fast.
When they created a fake wound, and applied human saliva, it healed in 16 hours. A protein in saliva called histatin is anti-bacterial and promotes cell-repair. It’s easy to create, so could soon be on our shelves in salve form as an active alternative to antibiotic creams.
