Therapeutic Grade Essential Oils is a Potentially Misleading Claim
No governmental agency or generally accepted organization "grades" or "certifies" essential oils as "therapeutic grade," "medicinal grade," or "aromatherapy grade" in the U.S. There is no formally approved grading standard used consistently throughout the essential oil industry.
Throughout the years, I noticed a number of companies that use these terms. Until writing this article, I hadn't given these terms serious thought.
I've been a member of the National Association of Holistic Aromatherapy (NAHA) for a number of years. Upon renewing my membership several years ago, I spotted that their membership application/renewal form, at that time, prohibited membership to those companies that use these terms. It was that policy that lead me to then take a fresh look at the terms therapeutic grade and aromatherapy grade and realize how confusing these terms can be to consumers. Having said that, I have noticed that NAHA, under different leadership, no longer includes the statements on their applications that prohibit membership to companies that use these terms.
I first began studying aromatherapy in the 90s. Thankfully, I never got caught up with particular MLM companies that make marketing claims and promote practices that I find concerning and unsafe. I was avoiding these companies for other reasons and did not realize until I had inquired with NAHA's president at the time, Kelly Holland Azzaro, that the term "therapeutic grade" was apparently coined by one MLM in particular.
By the time I first learned about holistic aromatherapy, a number of companies, including those that I otherwise find highly reputable, were also using the terms therapeutic grade and/or aromatherapy grade. I didn't see anything malicious with these terms and the terms seemed to act as a way to quickly convey to consumers that the seller's essential oils were carefully sourced specifically for use by those seeking oils for holistic aromatherapy use.
Most essential oils are distilled and standardized (adulterated) for use in other industries, so those carefully sourcing and selling essential oils intended for aromatherapy and therapeutic applications understandably do want a way to convey the suitability, purity and quality of their oils for therapeutic uses. Soil conditions, seed quality, climate, altitude, growing conditions, harvesting, the care during distillation, bottling and storage can all play a part in the resulting quality of an essential oils. These are all factors that conscientious suppliers pay close attention to. Using these two-word terms seemed to be a concise way for suppliers to designate that their oils were suitable for use by those seeking oils for use in holistic aromatherapy.
Though I'm a skeptical sort, I didn't originally find anything concerning about companies that used these terms. After much more careful thought back at the time I noticed NAHA's previous stance in prohibiting companies who used the 'grade' term from joining NAHA, I realized how truly meaningless and misleading these terms can be.
I have been especially concerned about one MLM's claims. Marcia Elston of Samara Botane wrote a detailed blog post, One More Time: There Are No FDA Certified Pure Therapeutic Grade Essential Oils, Part I, that details the particular concerns regarding this company.
Recommendations for Consumers
The key point to bear in mind:
Though these terms can be misleading, not all companies use these terms with intentional deception in mind.
If you come across a company that uses the term aromatherapy grade or therapeutic grade, look for other key indicators of their essential oil quality and attempt to assess their particular intent is behind their use of the term. Some companies provide details on their site that define their particular usage of the term.
Use the tips within AromaWeb's How to Buy Essential Oils article to guide you on what to look for when considering suppliers. Companies that use the terms "therapeutic grade" and "aromatherapy grade" may simply be trying to quickly convey to you that their oils were carefully chosen and tested for use by those practicing holistic aromatherapy. Some companies still have no idea that these terms are confusing.
Having said that, you still do need to be careful... Some companies do use these terms in a manner that is intentionally misleading consumers.
Carefully read the below AromaWeb articles for tips that will help you evaluate companies that sell essential oils and help you better understand how to access essential oil quality.

NAHA created an E-Booklet Series and prepared a very helpful 22-page booklet entitled Quality of Essential Oils. This booklet is Volume I in the series and is available to members (I received mine with my NAHA renewal confirmation email).
Recommendations for Essential Oil Suppliers/Retailers:
For those businesses that want to replace their use of the "grade" terms with a less misleading term, therapeutic quality helps to convey the intent without using the misleading word "grade."
Kelly Holland Azzaro, president of NAHA at the time, shared the following suggestions:
- pure essential oils for therapeutic applications
- pure essential oils (or organic if that is the case) for aroma-therapeutic use
- quality essential oils used in professional aromatherapy
A Note About AromaWeb's Advertisers
I strongly encourage AromaWeb advertisers to refrain from using the "grade" terminology, However, a few AromaWeb advertisers do still use these terms. It can be difficult for some companies to go back and change all the many references they may have used with the word "grade."
