Why doTERRA? First of all, let me start off by saying doTERRA is growing exponentially each year in sales because they filled a need. That need was for essential oils to have a scientific standard of testing and regulation available to the public.
There is currently no regulation on any of the essential oils sold in store or used in products (yes, even natural ones). Often they contain fillers, synthetics, or other unknown substances and are not 100% a pure oil. To bring this point home, I want to share with you that doTERRA is the brand John Hopkins University chooses to conducts their essential oil research with. This study about the effectiveness of essential oils against antibiotic resistant bacteria was done using doTERRA oils.
Before I started researching where my essential oils came from I purchased them at my local health food store. I never looked into them or imagined what I was getting was anything other than the oil I was purchasing. There was no disclaimer or information provided. In fact, labels like “pure” and “organic” were used to make the product appear more attractive while being misleading.
Let me repeat it again – there is zero quality control standard that essential oil companies must adhere to. The following image is of the back of a bottle of a brand of essential oils I used to buy:

The ingredients say each drop contains 0.007ml of oregano oil and the rest is olive oil. A drop of essential oil is about .05ml, so that means only 14% of this bottle of “oregano oil” is actually oregano oil. The cost of this bottle is $17.99 CDN. I was paying $17.99 plus tax for about 2ml of oregano oil. Even olive oil sold in stores these days isn’t 100% olive oil! Click here for an article warning consumers about this. Bottom line is when companies do this with essential oils we just don’t know what we are getting.
On the other hand, doTERRA’s 15ml bottle of oregano oil contains 100% pure oregano oil – that’s it! They are third-party tested by a reputable company and the tests done on each batch are available for anyone to see online.
