I use oregano oil too. I'm currently treating my warts with it. I have several warts on my hands and feet. I've been applying the oil to the affected skin for a few weeks now. So far, 2 of the warts have gone away (one of which has been there since I was 13!), and the rest of the bumps are starting to lose their ugly appearance. It is important to dilute the oil first before using it on your skin because it is a very harsh and strongly concentrated oil and can cause irritation or burn your skin. I made the mistake of not diluting it first and it started eating away at my healthy skin. I now dilute mine 10 parts vegetable oil to one part oregano oil, and it is fine on my skin now.
