Course description

Essential Oils have been used for thousands of years. When you choose our oils, you are choosing Essential Oils gently and carefully distilled from plants that have been patiently harvested at the perfect moment by experienced growers from around the world for ideal extract composition and efficacy.

Experienced Essential Oil users will immediately recognize the superior quality standard for naturally safe, purely effective Essential Oils.

• Provide health–conscious individuals with a safe and natural alternative.
• Used for a wide range of emotional and physical wellness applications.
• Have few, if any, undesirable side effects when used as directed.
• One drop is all that is needed to achieve a powerful benefit.


Our company has also perfectly melded modern advances and testing procedures to ensure the purity and efficacy of each Essential Oil.

Every dōTerra Essential Oil & Product is put through the highest standard of rigorous and thorough testing.

This testing protocol sets the bar for quality, purity, efficacy, and consistency.

When an Essential Oil is deemed worthy to be sold as one of our Essential Oils, you’ll know that it has the highest quantity of active, beneficial constituents and that it is free of contaminants and adulterations.

Because we know that the same care and attention—as well as the same commitment—to only provide the very best is not unique to us; they’re the same qualities you employ when taking care of those you love the most.
