Essential oils can be a touchy subject with people, especially those who feel very strongly about the company they use. I have personally used one of the most popular brands because a friend did and she signed me up so I could get a discount. That was a long time ago...and life happened and I never really got into them and didn't order for a very long time... years.
Then EOs got really, really popular. Everyone and their cousin was joining up with some EO company. I reached a point in my life that I was interested in checking them out again, but when I went back to the company I had joined way back when, I was required to purchase over $200 worth of oils just to get my account back. I understand $200 isn't hard to spend in oils, but I wasn't about to do that and be chained to the company in this way. So I went on a mission to find out what other people thought.
So searching the good old inter-web, I came upon a lady who did a very extensive, in depth, review of some of the major EO companies and a few that are not as well known. Yeah for me! It was done in a non-bias way and she actually contacted the companies and talked with owners about their practices and much much more. I was impressed at the time she put into it. She of course had her critics, some not very nice at all, but I took her work to heart and made my own decision.
Her review and conclusion is HERE. I found it very interesting because her conclusion was a company I had recently found and was already looking into. Besides the two listed below, I also use oils from Melaleuca and Mountain Rose Herbs.
Long story short, I personally think if you find a company(s) that you love for your essential oils, great! I don't like all the negativity toward other companies or people who force theirs on you and make you feel like you are a horrible person if you use or think some other oil is good too. Take it or leave it, hate me or love me...there are more important things in life.

I have been using these for a few years. I really like that they are very transparent about their safety and test results.
