Vinegar: This really works and I am amazed. I have tried expensive fungus treatments and they have also worked, but at a cost. Now thanks to Earth Clinic I have found a treatment that works for a cost of pence. I can see a good sized band of new nail on every toe. I bought myself a dropper bottle for easy application. I didn't want to write a review until I was really sure vinegar worked, but as nearly half of my big toenails are clear in colour instead of brown I feel I can add my review. I am not the best at doing it twice a day as recommended, but always do it at least once a day.
