Hmmm, personally I would try the oregano first, and then switch to lemon, or alternate between the two. The key here is that your oils are pure and have been distilled at the right pressure and heat in order to preserve the delicate chemical structure of the oils, as well as distilled with water rather than alcohol or some other base.
The oregano shouldn't burn if you don't get it on the sensitive skin around, or else, you can put a layer of olive oil around the area (not on the wart), and then put the oregano (just a dab) on the wart, and do this a few times a day. Let us know your results!!
