Spit Takes
Some amazing things you probably didn’t know about
all that gross water that lives in your mouth.
The phrase “licking your wounds” comes from the practice of animals nursing themselves back to health by literally licking their wounds. And it works. The saliva of many animals contains antibacterial enzymes, such as peroxidase, cystatins, and lysozyme, as well as the antiviral compound thrombospondin. Saliva also contains various nitrates that turn into nitric oxide upon skin contact, which stops bacteria from growing. Further, opiorphin is present in saliva—it’s an analgesic, or painkiller.
