You may be able to treat toenail fungus at home with certain essential oils and other products with antimicrobial and antifungal properties, like Vicks VapoRub.
Toenail fungus, also called onychomycosis, is a common fungal infection of the toenail. The most noticeable symptom is a white, brown, or yellow discoloration of one or more of the toenails. It may spread and cause the nails to thicken or crack.
Sandal season or not, toenail fungus typically isn’t what you want to see when you look at your feet. There are many treatments you can try, and some of them can be natural.
