An essential oil is a natural product extracted from a single plant species. Not all plants produce essential oils, and in the plants that do, the essential oil may be found in the roots, stems, leaves, flowers, or fruits.
What is the difference between "aromatherapy" and "essential oils"?
Basically, these terms mean the same thing. We think the term "aromatherapy" is a bit of a misnomer because it implies that all essential oils smell nice. On the contrary, there are many essential oils that do not have a pleasant odor. While smell is very subjective, German chamomile is an example of an essential oil that does not appeal to many people. Also, the name "aromatherapy" implies that smelling, or inhaling, essential oils is the only way to get therapeutic benefit, but there are actually a number of ways to use essential oils.
While we think the term "essential oil therapy" is a more descriptive name for this topic, we refer to it as "aromatherapy" because it currently has better name recognition.
