Interesting! I had no idea! I'm always amazed at the amount of things I learn on here!

Just remember it has to be your spit/saliva and it works a treat.

I have done that, works great!!!!!

I was told yrs ago your own spit takes out your own blood. Works for me all thhe time.

Spit works on your own blood because of your body's enzymes, a cool fact.
Thread a wet needle with a dry thread, don't lick that, too.
