Essential Oils are not all created equally so first, it is very important to make sure that you thoroughly research any Essential Oil company  that you consider using. Young Living Essential Oils have been around for 20 years and the purity of their oils is guaranteed by their proprietary Seed to Seal process. This process ensures that their oils are genuine, free of synthetic chemicals, and are of unmatched purity. Here is some information about each step that Young Living takes to create such safe and effective oils and this video explains even more...  Seed to Seal

Seed- Powerful, effective essential oils come from seeds and plants that are verified for their essential oil potential by Young Living experts, partnering with university experts.

Cultivate- Young Living farms, located around the globe, are dedicated to perfecting the best growing and harvesting methods. Our experts also travel the world visiting our co-op farms to verify that their growing and cultivating processes match our high standards. These operations provide an ongoing source for essential oils that meet Young Living’s demanding quality standards.

Distill- Combining ancient and modern techniques, Young Living is recognized as an innovator in essential oil distillation. We use a gentle, proprietary technique for steam extracting the most effective essential oils, as well as using cold pressing and resin tapping methods for select oils.

Test- Young Living never accepts diluted, cut, or adulterated oils. To guarantee consistent quality, our oils are tested in Young Living’s own internal labs, as well as in third-party facilities, to ensure that they meet stringent specifications, exceed international standards, and contain the optimal levels of natural bioactive compounds.

Seal- Young Living completes the Seed to Seal process in its 107,000-square-foot facility in Spanish Fork, Utah. Using state-of-the-art equipment, each essential oil is carefully bottled into protective amber glass bottles—ready to be shipped to members worldwide.
