I, too, have a natural remedy. Last year, my 7 year old daughter started to take gymnastics. As a result, she developed the lovely, large wart on the bottom of her toe.
We had a trip planned for Disney in February and I feared that her wart would negatively impact all the walking we would do at Disney.
I tried to be proactive and took her to the doctor in January...the doctor froze it but the wart remained. As the visit cost me about $300 ( we have a high deductible health plan and are responsible for the first $4000), I was not going to go that route again.
We tried cutting it, but understandably, could not get my daughter to cooperate.
Out came the natural remedy books and we found this one...each night, we would soak her foot in warm water with some vinegar added to it. Immediately after the soak, dry it, slather it with castor oil (found at Walgreens) and wrapped it with a bandage. We would leave the bandage on for the rest of th night and take it off in the morning. Each night we would repeat this same process. Within about a week and half , the wart was completely gone.
I think the key is suffocating the thing...especially after reading these emails with the different natural remedies, that seems to be the common factor.
Good luck!
