First, doTERRA goes into nature and practices Cō-Impact Sourcing® by sourcing its oils from all over the world so that each oil is derived from its indigenous environment where the plants naturally grow best. When they are grown and harvested in the proper altitude, climate, seasons, and soil, you end up with a far superior product. This is where dōTERRA®'s commitment to purity begins!
The second important reason is that doTERRA oils are CPTG Certified Pure Therapeutic-Grade® (CPTG) so that every oil has ZERO fillers, synthetics, dyes, pesticides, or contaminants of any kind. They are pure and unadulterated oil. dōTERRA® created this standard as a promise of purity and each and every batch is THIRD-PARTY TESTED outside of doTERRA to verify so you can be confident in not just their purity, but potency as well.
