I have Immune System cancer (Multiple Myeloma) which means that while under treatment and during recovery, I have a very difficult time fighting off bacteria, viruses and fungi. After a lifetime of never being plagued with toe fungus, I got it this summer and nothing was working to fight it back. After conferring with the lovely people at this company, I gave this a shot. I layered it on every morning and night onto a clean toe and, miracle of miracle it worked and the gross nail is growing out with healthy nail beneath coming in! I have now moved on to using this on non-cancerous spots on my skin (always check with the dermatologist first to make sure it's not cancerous) and I am seeing healing in those places. It's important to be patient and consistent and to support all health with sleep, hydration and nutrition. So thrilled to have an option that doesn't include the usual endless prescription bottles!
