My Dad's oil pulling experience has been pretty cool.
At Thanksgiving Dinner 2006 he showed me a black spot that he had on his tongue about the size of a dime. I told him about the oil pulling and he started immediately. At Christmas the black spot was almost gone.
In the meantime someone here on curezone had posted the map of the tongue and I realized that this spot corresponded to his kidneys. He had told me at Thanksgiving that the doctor said that his kidneys were only working at 40%. By Christmas he said that his last results said that his kidneys were up to 60%.
At a birthday party in March he showed me his tongue and it was completely clear, and he said that his kidney problems were gone. He also had what I call liver spots on his forehead and on the back of his hands, and these were gone by then as well.
