In what can only be described as a major medical discovery, saliva contains a painkiller that is stronger than morphine, six times stronger, in fact. But what exactly makes a discovery like this so amazing, and if this happens to be the case, why are we able to feel pain at all? I mean, most people swallow their own saliva, shouldn’t that act as a painkiller on its own?
Morphine is regarded as one of the strongest painkillers that can be used, but it has its problems. Aside from being potentially deadly, it’s also highly addictive. It’s use is generally restricted to those in severe debilitating pain. The painkiller in saliva that is stronger than morphine, on the other hand, is not addictive at all, and as far as anyone knows, is harmless.
