You can let @allforthegood know that one recipe for wart removal is:
Combine 5 drops cypress oil, 10 drops lemon oil, and 2 Tbsp apple cider vinegar. Apply on location twice daily and cover with a bandage. Keep a bandage on until the wart is gone.
Some other essential oils that may help: frankincense, On Guard (protective blend), melaleuca, oregano, and clove. You can dilute 1-2 drops of any of these oils in a carrier oil (coconut, olive, etc.) and apply 1-2 drops daily.
Hope this helps!
