After burning, lazer and cutting out a planter wart, nothing removed the root.
Finally, I soaked my foot during a bath and taped a small peice of aloe vera leaf
right onto the wart. After a few days of repeating this, the wart left for good and never returned.

I don't know how natural this is....but I've heard duct tape works.

Wart Plant can be bought from Riechert's Herbs onlin, don't know if you can get it other places, like a health food store. The juice from the stems is rubbed on the wart and it falls off in a few days.
Plantars warts are hard bumps found on the soles of the feet, they tend to grown inward due to the pressure of the foot and should NEVER be dug out, or they can spread badly. Ever see a crocus plant when it starts the little baby bulbs? Like that. My sister has one that she dug at as a kid, now it has a name and even doctors can't remove it.
Best bet is to get the over the counter plantarts wart treatments. It is salisylic acid, the ingredient of willow, which is aspirin. It destroys the wart a little at a time, which causes the plantar version to move outward as it is killed, eventually eliminating the wart. On other surface warts, this process is easier. If the plantar wart is left untreated, it will evetually become painful for your daughter to walk on it, like having a pebble stuck under her skin.
Best wishes and hope she is better very soon! PS remind her not to pick at it

Thuja oil works very well. It's made from cedar.

My favorite source for it is here...

I've been buying from Denise for many years, and the quality of her herbs and oils is phenomenal.
