DISCALIMER: Essential oil (EO) should not be used to replace medication & medical treatment or prevent & cure Covid-19 or other diseases. You have to abide to the safety guidelines (such as the amount, how and restrictions of usage) when using EO.

As a form of aromatherapy, research into the effectiveness of essential oils is on them inducing calmness and relaxation. Essential oils can also increase a person’s tolerance to pain. This works as pleasant scents from essential oils send signals to the brain to release feel-good chemicals. However there are no clinical trials to prove some of their other benefits. (Source)


These labs below (and others) analyze the detailed chemical breakdown to detect desirable Major and Minor components and verify the absence of undesirable components; adulterant, contaminant or diluent to determine purity of EO.

Purity is important because additives that are used to dilute or imitate an essential oil could trigger allergic reactions and impact the effectiveness of the oil. 

  • Essential Oil University (EOU in USA, essentialoils.org) – Founded by Dr. Robert S. Pappas (aka “Dr. P”), a PhD chemist who specializes in GC/MS (Gas chromatography–mass spectrometry) analysis and reporting the chemical breakdowns of hundreds of different essential oils, CO2s and absolutes. 
  • Laboratoire Phytochemia in Canada | phytochemia.com 

For example, “Conclusion” of a pure essential report may look like this: 

Example of adulterated (not pure) essential oil report:

Factors that determine EO Quality

  • Processing – Distillation, equipment, packaging, handling, storage. Sometimes they are adulterated, contaminated or diluted (to save cost, achieve the desired aroma, etc.)
  • Plant used to obtain the oil – species, which country it is cultivated from, environmental conditions, use of chemical etc.
