Why most essential oils on the market fall short — and how doTERRA's CPTG standard addresses it.
Purity and quality are often spoken about together, but they are not the same.
A high-quality plant can produce high-quality oil — but due to modern sourcing processes, it may become adulterated, making it impure. Likewise, an oil can be technically pure but come from low-quality plant material, limiting its effectiveness.
True integrity lies in the consistent meeting of both: oils that are unaltered and sourced from healthy, carefully grown plants.
In much of the essential oil industry, oils pass through multiple intermediaries before reaching the end user. With each step there is pressure to increase profit — and this is often where dilution or substitution occurs. An oil may be extended with a carrier oil, have cheaper similar-smelling compounds added, or be labelled as a species it is not. The essential oil market is largely unregulated.
CPTG stands for Certified Pure Tested Grade — doTERRA's internal quality standard. Every batch is independently tested for purity and potency by third-party labs before it can be sold. No synthetic fillers. No adulterants. What is on the label is what is in the bottle.
Testing includes:
doTERRA works with multiple independent third-party laboratories to test each batch — not just their own internal lab. Results are published at sourcetoyou.com, where any oil can be traced by lot number from farm to bottle.
