Usually when I talk to doctors about medical issues, I just ask for the sake of finding out for myself. however, I recently have decided to take some time to write down my doctor's views on Vicks Vapor Rub as a cure for toenail fungus.
According to my doctor, there are many types of fungi out there that can infect your toenails, so there is not necessarily an "end all cure" for toenail fungus. However, if you want to get rid of it for sure, he said you do need to use a product that actually kills fungus. Vicks Vapor Rub is not a product that is able to kill any kind of fungus, even toenail fungus.
Vicks Vapor Rub is simply a petroleum based gel that contains menthol. Petroleum is harmless and is use primarily as a lubricant and as a sort of moisturizer. It will make our toes softer, but it will not kill the toenail fungus on or around your toenail. You need something more potent, or something with an active ingredient much stronger than menthol to get the job done.
So, there you have it. Vicks Vapor Rub will not cure toenail fungus, because it does not even kill fungus. If you are serious about fixing your toes, use a product that actually kills toenail fungus and you will see results. I have personally used a couple of products that worked very well for me, and wrote about them in a previous post called Vicks Vaporub for Toenail Fungus - Alternatives. Feel free to check it out and decide what might work for you.
