All of these essential oils are 100% pure with absolutely no fillers, diluting oils, synthetic fragrances or unnatural components of any kind. They’re also tested on 3 different occasions for purity and potency. After they’ve been tested, we bottle the oils in black matte bottles so no light or oxygen can reach them. Then they’re stored in a temperature-controlled building while they wait to be shipped directly to you. Organic These essential oils are certified organic whenever possible. To become a certified organic farm, there are a lot of hoops to jump through and it’s a serious financial commitment. Since we work with small farms across the world, they’re not always able to become certified. However, 8 out of 15 single-origin oils are certified organic, and all the farms we work with are non-GMO.
