oil of oregano

I've been using oregano for years as a spice, especially in spaghetti, but today I learned of a new use.  I happened to click on the Dr. Oz show when I got home from work and he was extolling the virtues of oil of oregano.  Who knew there even was such a thing.  Evidently, if you put just a drop in some coconut oil it makes an inhalant (under a towel) that will clear your sinuses, and if you mix it with equal parts of olive oil it will clear up pimples and skin rashes, just a tiny dab will do it.  I haven't actually tried this yet, you understand, but it did sound interesting.  I think I'll recheck the directions on his website before I actually do any of this.
