I asked this same question just recently and got the above answer as well as trying Whole Foods, or, http://www.mothernature.com/ I can't vouch for any of them since I haven't used them yet. I bought some of my essential oils at GNC, but afterwards realized that they aren't organic. I will use them up and then try some others. I found Tea Tree oil at Target, of all places. It was a large bottle, wasn't too expensive, and was pharmaceutical grade. I'm using mine for making natural cleaners, since I'm allergic to bleach and most cleaners. If I may be so nosy, what are you doing with yours?
