The essential oil market isn't uniform

The term "essential oil" isn't legally protected in a way that guarantees consistent quality — products sold under the same name can vary enormously in purity, sourcing, and the presence of contaminants. That's why, when choosing oils, it's worth looking beyond price to how a producer approaches quality control.

What the CPTG standard covers

Why plant origin matters

The same plant grown under different climate and soil conditions can produce oil with a different chemical composition. dōTERRA sources many oils from the regions where a given plant naturally thrives (a co-impact sourcing model), which affects the quality and authenticity of the final product.

What this means for everyday use

Choosing an oil with a documented testing process gives you more confidence that you're getting exactly what the label says — without unexpected additives or dilution with cheaper substitutes.
