There are many companies in the world producing pure essential oils. But finding those companies may not be the easiest of tasks, and even if you find them, they may not be selling their product in small retail bottles. As a general rule, the farther down the supply chain you go the less likely you are to be getting pure product. There are a lot of companies out there selling essential oils and most of them have no ability (or in many cases no desire) to do the necessary quality control to verify what they are getting from their supplier before they pass it on to their customers. Additionally, pure does not necessary equate with good quality. A pure oil can be distilled incorrectly or could have been obtain from a particular variety of plant species that was not ideal. Furthermore, with regards to therapeutic grade, we need to be diligent at discerning what the claim really means. There seems to be a misconception that there is some kind of independent body that certifies oils as therapeutic grade, but to this date there is no such body, at least not one that is widely recognized. Does this mean there is no such thing as therapeutic grade? No, but just realize that any therapeutic grade standard out there right now is an internally derived company standard. Now this standard may be an overall great standard and perfectly acceptable to me or any other analyst or aromatherapist out there but it just needs to be noted that its not an independent standard. Some of the company standards that I have been privileged to access have in fact even been quite exceptional in some cases, surpassing the conventional standards of ISO, etc. In the end, for most people who don't have access to their own GC/MS, it all boils down to who do you trust to give you the pure oil. If the leader of a company has a history of misinformation, arrest records for practicing medicine without a license, getting sued for injuring people by improper use of essential oils, using the names of credible people inappropriately for personal gain, and questionable ethics in general then its probably not a company whose "therapeutic grade" standard would really carry much weight with the aromatherapy community at large and should also not be taken seriously by an educated EO consumer.
