Good question!

I have MH 's oregano oil Im saving for after i use up the stuff I already purchased.

His is much stronger than the type you buy in most healthfood stores.

The one I use til I finish it is from "Herbal Authority". It doesnt say what the ratio is- only that it is 45 mg. mixed in Cold pressed olive oil.

I think I have some kind of small thread worm or such in my ear canal, I felt a little movement there so I put about three drops of this stuff in my ear. You could feel a burning feel. Later as I slept, I could feel some thumping sensations in that ear which could be a blood vessel, but I think was probably the worm trying to escape the oregano oil.

I dont know how safe it is to treat yourself this way by yourself. I was lucky that if it was actually a worm- it didnt block one of my blood vessels going into my brain while the oregano oil was hurting it. In any case, that stuff is potent and worms hate it!
