Saliva from humans has yielded a natural painkiller up to six times more powerful than morphine. The substance, dubbed opiorphin, may spawn a new generation of natural painkillers that relieve pain as well as morphine but without the addictive and psychological side effects of the traditional drug. Opiorphin works in nerve cells of the spine by stopping the usual destruction of natural pain-killing opiates there, called enkephalins.

Penso que não é a saliva que seja o anestesiante..... mas aquilo a que leva à transmissão de saliva é que é o mais perfeito dos calmantes naturais :P
