THIS IS NOT AN ADVERTISMENT ....No...DO. castor oil........ within 7 days I have had it for 25 years nothing else works I've tried so hard to get rid of it and it's looking really good the fungus looks under a microscope looks like to be parasitic worms but castor oil will do it and I also use some dewormer on them because they look like worms to me. I'm guessing it's all related because the toe was terrible. Most all phones have a microphone on it and also you can download a microscope from the App Store for free set it up to 6 and it look at the fungus toe. You really need to have it for this journey
