1 part thyme oil
1 part Celandine extract
2 parts apple cider vinegar
Combine all ingredients and soak up in tiny bit of cotton, just enough to cover the wart. Apply to the wart and cover with tape or a bandaid. Remove and carefully wash the area once a day and replace with a fresh cotton ball. The wart should be gone within 2 weeks.
This method kills the wart and can damage the surrounding skin, so make sure the cotton ball is only covering the affected area. You can smoothe aloe vera over the surrounding area and let it dry after you wash the area each time you change the bandage to help protect the surrounding skin, or protect the skin with cocoa butter or beeswax salve (or petroleum jelly if you absolutely must).
Also, this hurts. Alot. But not as much as having them frozen off.
Note: If you don't have all the ingredients, don't worry. Vinegar is the key ingredient here. You can use any kind of vinegar by itself if you're in a pinch.
