The purity of an essential oil is its most important characteristic. An essential oil that isn’t pure means you run the risk of putting germs, heavy metals, or adulterants onto or into your body, which can provoke irritation, adverse effects, or even sickness. Without an accepted standard for essential oil quality, doTERRA created its own testing process, calling it CPTG Certified Pure Therapeutic Grade®. The CPTG process certifies that there are no added fillers, synthetic ingredients, or harmful contaminants in their essential oils that would reduce their efficacy. doTERRA even goes a step further, putting all their products and the packaging through a battery of tests to ensure a long and effective shelf-life. This protocol ensures potency, purity, and consistency batch to batch.
Before the CPTG® Process Begins
Proper methods of growing, harvesting, and distilling are also crucial to maintaining purity. Poor production practices and the development of synthetic essential oil variations suggest that it is impossible to accurately identify a pure essential oil without scientific analysis. Appropriate analysis of the constituents within an essential oil is one of the most challenging and detailed aspects of quality assurance.
Knowing which of the many different species of a given plant will provide the most profound therapeutic health benefits is the first step in producing the highest quality essential oil. Relying on the expertise of botanists, chemists and wellness practitioners, botanical materials are carefully selected for their natural concentrations of active aromatic compounds.
Nurturing plants in the most favorable environment and carefully harvesting and transporting plant material for processing ensures an optimal yield of pure and potent essential oils. Spanning the continents of the globe, doTERRA’s exclusive network of growers and harvesters are experts at cultivating plants specific to the essential oil industry.
The CPTG® Process
The CPTG testing begins immediately after distillation with each oil being reviewed for its chemical composition. A second round of testing is carried out at our production facility to ensure that what was distilled and tested is the same essential oil as was received. A third review of the chemistry of the oil is conducted in a three-phase procedure as the oils are packaged into the bottles we use as consumers. Each of these tests confirms that the essential oil is free of contaminants and unexpected alterations during production.
The CPTG Certified Pure Therapeutic Grade quality protocol includes the following tests:
- Organoleptic testing
- Microbial testing
- Gas chromatography
- Mass spectrometry
- Fourier Transform Infrared spectroscopy (FTIR)
- Chirality testing
- Isotopic analysis
- Heavy metal testing
This strict series of testing ensures that every doTERRA oil produced is of the highest quality so you can feel good about using it on your family. Please note, not all companies have the same high standards for their oils, so please carefully read any bottle of oil to ensure it can be used like the doTERRA oils- aromatically, topically and internally.
