Via io9, ‘You Have a Painkiller Six Times Stronger Than Morphine In Your Saliva. Right now, you are walking around with a mouth full of extremely powerful, untested pharmaceuticals. Your saliva contains opiorphin, a painkiller thats about six times more powerful than morphine.
After so many decades spent prodding lab rats, one would think that there is nothing more to be discovered about the horrid little things, or how they relate to humans. One would be wrong. What a fool one is! In the early 2000s, scientists discovered that rat saliva contains sialorphin, a powerful painkiller. Rats are, in many ways, analogous to humans. Researchers began wondering if human saliva contained its own painkilling compound.
Enter opiorphin, a painkiller that seems to be both very effective and very simple. It works by preventing the breakdown of little chemicals called enkephalins. These chemicals stimulate the bodys opiate receptors, which block pain signals. Liberal application of opiorphin keeps the bodys own pain-blocking system going. Why such a powerful pain-killer is in saliva is up for debate…
