Had toe nail fungus for a long time and it was very stubborn. I tried many things… nothing work. It was white and powdery. I believe I got it from previous owner when I moved in my new house and my toe nail was blue and broken at the time. I could see yellow spots began to appear on the nail and it became white later on and it spread to my other toe nails. When I switched diet to alkaline diet a year ago I was surprised to see the fungus disappeared by itself. I also drink ACV every day so perhaps combining ACV with alkaline diet helps a lot more. I believe the fungus indicate the state of your health.
