Dealing With a Plantar's Wart

My son discovered a small plantar's wart on his foot about a week ago. I decided to see if there was one of my essential oils I could use on it rather than buying the kit that you use to freeze them. Sure enough, I found a testimonial about using the Young Living lemon essential oil that comes in the Everyday Essentials kit.

Just put a drop on once or twice a day and it'll be gone in no time. Well, it's taken us about a week to do 4 applications (we keep forgetting) but when we did the 4th one this evening, I noticed the wart is almost entirely gone! Oh my goodness, how I wish I had this available to me when I was a kid. I have a clear memory of being at my grandparents for a week for Christmas and having to soak my foot, rub the wart area down with a pumice, put the medication on...

Have you used an alternative to the modern freezing kits? Please share!
