What are essential oils?
Essential Oils are the naturally occurring volatile oils obtained by steam distillation or cold pressing (expression), having the characteristic aroma of the plant part from which it was derived. These pure oils are "neat", meaning they have not been processed, diluted or manipulated in any way with solvents or other additives. Although a particular species of plant harvested and distilled for its essential oil during a particular growing season in a specific region may produce a fragrance that differs from the same species grown in a different region, many of the main chemical markers and physical specifications may be very similar.
NOW's citrus fruit essential oils are 100% cold pressed. Our other essential oils are typically 100% steam distilled.
Do essential oils have a grading system to tell me which is better?
There is no official grading system that grades essential oils as A, B, C or Therapeutic grade. All NOW pure essential oils are accurately labeled as such and are the highest purity and quality available.
Are NOW essential oils pure or do they have anything added to them?
All of our pure essential oils are labeled as such. We also sell clearly labeled oil blends that are formulated with essential oils or absolute extracts and another oil as a base, usually pure grapeseed oil.
Natural Essential Oils by their very nature will vary slightly from season to season. We allow nature to take its course and do not add isolated compounds to the oil to try to standardize the naturally occurring variations of a particular oil. We take both the organoleptic (sight, smell and taste) and chemical properties into account when selecting and testing NOW essential oils.
What are NOW's criteria for testing essential oils?
Our Quality Assurance and Quality Control departments adhere to specifications used by the Essential Oils and Flavor Industry and published in The Essential Oils by Guenther, as well as Fenaroli's Handbook of Flavor Ingredients.
These texts, as well as other sources of scientific information, detail specific physical and chemical properties of a particular oil. A partial list of the components that we analyze include Specific Gravity, Refractive Index, Optical Rotation, Flash Point, Infrared Absorption (as published in FCC), Solubility, Taste/Odor, Color/Appearance, Heavy Metals and Predominant Active Chemical Components.
Our in-house laboratory employs state-of-the-art analytical equipment that allows us to perform highly specialized analyses, such as Gas Chromatography and Infrared Spectrometry. We use our own analysis results to confirm specification sheet results and certificates of analyses received from 3rd party outside laboratories and vendors. As always, when it comes to Essential Oils, individual practitioners and consumers will decide for themselves which variety of a flower or leaf produces the essential oil that best suits their particular need. With NOW pure essential oils, you can be assured that you have the real thing.

My family and I have been using Cassia essential oil topically on our feet. Is this OK since your bottle says "Not for Topical use"?
Skin irritation is possible with many essential oils, including Cassia or Cinnamon. Though many people do use our oils in a variety of ways, due to the powerful nature of steam distilled pure essential oils we label these products with cautions and suggest that you consult an aromatherapist or health professional for proper use. There are many good reference books on using essential oils safely.
These pure oils are of the highest quality, undiluted and unadulterated. They are appropriate for any use where these concentrated oils are indicated, either for aromatherapy or with significant dilution per an appropriate recipe for aromatherapy or massage oil blends.
