Being based in the UK, the only thing I would take issue with is the words, (Genuine and Authentic.) Here like, “pure and natural” they have no legal meaning. The way I ensure oils (apart from those I make myself by infusing herbs in a vegetable oil) are something I am prepared to use on my own and my clients’ skin is that they are certified organic and have the Latin name on the bottle. (Thyme for instance has at least five different chemotypes and it is only by referring to the latin name you can be sure an oil is exactly what you believe it to be.)
That said, you have given a much better description of aromatherapy than the more limited one currently on my site.
