"Oil pulling is a technique to clean your teeth and mouth. You put a spoonful of oil in your mouth, then swish it around for 20 minutes (yes, 20 minutes!!). Then you spit it out (into the trash can/compost bin, not the sink, so it won’t clog your plumbing)."
I just tried oil-pulling but after 6 minutes my mouth was so full of spit I couldn't stand it.
