Have you tried oil pulling, as recommended by Raster and Able on this forum? I started one week ago and have experienced positive results with my mouth and ultimately spitting up phlegm. I’m not sure where the direct link is on the forum, but this is the protocol with oil pulling:
* on an empty stomach, brush teeth/mouth thoroughly
* gargle with 1 Tblsp. unrefined virgin coconut oil for 10-15 minutes
* rinse mouth with salt & water
* brush teeth/mouth thoroughly
* repeat up to 3-times per day
It sounds rather disgusting, but surprisingly it’s not. Good luck!
