Some science behind the scenes
Opiorphin is an endogenous chemical compound first isolated from human saliva. Initial research with mice shows the compound has a painkilling effect greater than that of morphine. It works by stopping the normal breakdown of enkephalins. So if you spit or lick a wound, as animals do or as mother’s do it helps clean the wound , but it should also ease the pain. Dame Edna was absolutely right……….
“I have my own healing range called My Mother’s Spit. It was an accidental discovery. When you were small and grazed your knee, your mother licked her hanky, didn’t she? There’s something there, an enzyme. And luckily my mother is still alive and she’s drooling in commercially viable quantities. So we’ve harnessed that.
