Oil of Oregano for ears?

Yay, I got my OOO - thanks MH and John! Thanks for giving me a booklet with it too, John - I read it last night.

I have super itchy ears sometimes, like right now. The itch is deep, and drives me crazy. I am really really really hoping that it's not parasites....gulp. Anyway, could I put a drop of this diluted safflower/OOO in each ear? This is 12 parts oil to one part OOO ratio, right? Is that diluted enough, or should I still put a drop of it into a drop of another oil? I don't want to burn anything!
