Quality & Testing

In our quest to provide you with the purest essential oils, doTERRA puts every batch of essential oils through an exhaustive testing protocol. We established the CPTG® process, a stringent collection of physical, chemical, and stability testing procedures that ensure our oils are free of synthetics, additives, and harmful contaminants. Through this battery of tests, we can be confident that our oils are safe when used as directed and will remain so throughout the duration of their shelf life. doTERRA is meticulous in their quality testing so that you can trust that every bottle of oil you open is truly a “gift of the earth.” To learn more about each stage of the rigorous CPTG process, check out the articles listed below:
