What’s doTERRA On Guard?

Dr. Stevens began by breaking down the components of doTERRA On Guard: Cinnamon Bark, Clove, Eucalyptus, Rosemary, and Wild Orange. Each essential oil brings its own unique aromatic profile and incredible properties.

Many oil companies sell a protective-type blend, but Nicole explained, “The power of doTERRA On Guard is in how each ingredient complements the others. It’s not just about adding oils together. It’s about how they interact chemically and aromatically.”

The Science Behind the Blend

One highlight of the discussion was the doTERRA commitment to CPTG Certified Pure Tested Grade® quality standards. Every batch of doTERRA On Guard goes through multiple rounds of testing—from gas chromatography–mass spectrometry (GC/MS) and Fourier-transform infrared spectroscopy (FTIR) to heavy metal and microbial screening—to ensure purity and potency.

“We’re not just checking a box. We’re making sure every drop of essential oil lives up to the standard we promise our customers,” said Dr. Stevens.

She also pointed out the synergy between essential oils like Clove and Wild Orange isn’t random. Blends like doTERRA On Guard are designed with chemistry in mind to support a strong aromatic experience.
