A team from the Pasteur Institute in Paris, France, led by Catherine Rougeot, have apparently isolated an endogenous chemical compound from the human saliva known as Opiorphin, which is said to be a natural painkiller. This new natural painkiller was found to be 6 times more potent than morphine when tested on rats.

Opiorphin works by preventing the breakdown of little chemicals called enkephalins, which are found in central nervous system. These chemicals stimulate the body's opiate receptors responsible for blocking pain signals.
