Oil Pulling
Oil Pulling is pretty wonderful. There's an oil pulling forum here on cz. The premise is that the oil stimulates lymph and a pull from your body into the oil. Think of it like a siphon or an oil pump in a field. There's a gentle, continuous pulling motion that sucks stuff up a tube - the same is effectively true for oil pulling (or at least that's a general consensus). One of the ladies on the OP forum mentioned that having gingivitis, gum issues, cavities, compounds the infection in your mouth. When you think about it, germies in your mouth represent a lot of square footage of infection at the opening of your face. (dramatic, I know but it makes A LOT of sense).
When I started oil pulling, my breath got better and better, my allergies seriously decreased, my brain fog dissipated, my overall energy was better and - no lie - at about day 10, the stains fell right off my teeth. I spit the oil and there were little off-tan-color flakes in the sink and I looked up in the mirror and my teeth were WAY whiter. Gums that recede are repeatedly reported as coming back down the tooth as it helps heal the gum 'pockets' by clearing the bacteria so the mouth can heal itself.
