The nail polish is keeping the fungus in the nail and nail bed. I can recommend a website if you are interested in some anti-fungal herbs that will not only help the toe when soaked in but when drank will also help internally to reduce the fungus as well as to clear and heal the liver, kidneys, pancreas and spleen of any pharmaceutical damage. As an RN you should be aware of the dangers to the filtering and elimination organs from pharmaceuticals. I only give my family healing herbs and we don't have to visit the doctor anymore. We don't get sick except rarely now and when we have we recover extraordinarily quickly. Let me know if you want the web link.
