Follow the directions on the tube. For the nail fungus, get pure
tea tree oil and put that on your nail every day, twice a day if possible, but at least once a day. It will take months and it smells pretty much like turpentine, but it won't hurt you. There are oral antifungals, but they have the potential to harm your liver. You can take oral odorless garlic and a probiotic or prebiotic to get your system cleaned up. Avoid eating sugar to get your flora healthy again.
