I have not yet tried this but a friend shared this info with me recently:
Reading the Wheatgrass Book from Ann Wigmore, I want to share with you this incredible discovery :
Chapter " ARE YOU PROTECTED FROM THE HAZARDS OF MODERN LIVING? "
"A few years ago, I ( Ann Wigmore ) asked Dr. GH Earp Thomas of the Bloomfield Laboratories in High Bridge, New Jersey, to do an experiment for me. He placed a small amount of wheatgrass juice in a jar of regular tap water and he tested it for fluoride and other chemicals present in the water...
Both of us were surprised by the results!
He concluded, "Fluorine rapidly combines with calcium phosphate and other kinetic elements to lose its toxic properties, and harden teeth and bones. that is why fresh grass would act as a catalyst to speedily change the acid fluorine into a beneficial component with a positive reaction...
By using wheatgrass, which is comparatively rich in calcium phosphate, it would remove any free fluoric acid and change its negative charge to an alkaline calcium phosphate fluoride combination with a positive reaction"
I was amazed (Ann Wingmore )
not only did wheatgrass neutralize the toxic effect of fluorine but it converted it into an ally in maintaining healthy bones and teeth! I don't recommend that you drink tap water, though; pure spring or purified water taste better and is much better for you. But if you cannot obtain spring or purified water, pour a little wheatgrass juice into regular tap water, and it will make it more healthful..."
