[Mick] In my view, the very best essential oils are made by Young Living; and DoTerra oils are a close second. Those two companies are also the priciest by a wide margin. I have gotten very good oils for better prices from the following companies: Hopewell Oils, Appalachian Valley Natural Products, and Mountain Rose Herbs. I tend not to buy essential oils at a local health-food store because it’s hard to judge the quality of the brands that most stores carry. I never buy essential oils from somewhere like Walmart.
