Hi, PB. I don't know the specifics of what it would feel like to have boron attach to fluoride and leave the body. I've taken boron 3-9 mg for years, and I started it long before I knew to watch for some of these finer details. Ginagirl continues to write extensively about boron/borax. She compiled this boron reading list, including a reference to the website earthclinic.com concerning using borax for fluoride removal.
