Please contact Alliance of International Aromatherapists (AIA) or National Association for Holistic Aromatherapy (NAHA). Both these organizations maintain lists of classes offered by reputable providers, as well as schools that offer turnkey programs that will allow you to sit for membership in a professional organization or for the Aromatherapy Registration Council (ARC) exam.

Please note that an "aromatherapy certification" is an absolutely meaningless document, since any company can claim that they offer one. Receiving a certification from any given provider does not necessarily mean that you have recieved a quality education or are competent to perform aromatherapy.

What does carry some weight however, is a national registration (RA) from ARC or a CMAIA certification from AIA. Both of these mean that you have received 200+ hours of classroom training from a reputable provider in the industry, have shown minimum competencies, have passed a board exam (in the case of ARC) and are committed to continuing ed to maintain your registration or certification.

My company, Aromaceuticals, provides quality classes that can be used toward qualifying for membership in a professional organization and toward certification/registration. Although I do not have a 200 hour program in place at this time, individual Aromaceuticals classes will be accepted by portfolio review.

It's great that we can discuss these things.  In the United States, if you are looking for training, it's best to go to the National Association of Holistic Aromatherapy website.  They will recommend classes and home study programs. 
W. Dannie is correct.  The internal use of essential oils is NOT something most people should be doing.  The only recorded death by use of essential oils was from a child drinking them.  It can be dangerous.  In the US, it's best just to stay away from that all together.  It's not necessary either.  Topical application is therapeutic.  So there's no need to suggest internal use.  (It scares me just a little that these MLM companies are suggesting it)
And everyone is right about the CPTG labeling.  There is no organization that "certifies" any essential oils.  That's just something they throw on the label to try making themselves look good.

Back to your original question, Dayna.  One of the companies I use is this one:  http://av-at.com/.  It's not an MLM.  But one of the nice things it does is allow you to request the GC from the lot of stock you are purchasing.  For trained aromatherapists, this is great.  The GC is the chemical test they put essential oils through to make sure they're at therapeutic level and it's nice that this company just offers it up to you.  It's not a "full prove" method of testing essential oils, but it shows that the company isn't trying to hide anything from you.  It's willing to share and educate.  Hope that helps.

I purchase a good number of my oils from Mountain Rose Herbs and Imani Naturals who make very top quality oils at decent prices.

I will see that quality of oils is indeed important, but you will learn how to quantify the quality of the essential oils you purchase with your own experience. If you purchase oils from the local herb stores most of them carry at a minimum Aura Cacia, Frontier, and NOW brands. Aura Cacia is my 1st preference, Frontier my second and I avoid NOW like the plague. Now is the cheapest on the market and even though they claim to be 100% I have had too many of them go rancid. True essential oils will not go rancid, they can keep for thousands of years in a cool dark place. Only carrier oils will go rancid so if your EO's go rancid you can guarantee they have been cut with something to dilute it. 

Doterra and YLEO are both very high quality oil sources but are extremely high priced as well because they have to fund downlines. My suggestion is to seriously shop around and learn the oils for yourself. Make your own decisions using your own knowledge. 

I personally use Doterra and YLEO but mainly for their blends unless I get something free with purchase. They also have some very good educational material if you can cut out the bias. 

Regarding Kat's comment on aromatherapy education, NAHA is indeed a wonderful resource. So is Alliance of International Aromatherapists (AIA) which maintains a listing of classes and approved schools. I've been a member of both organizations.

Rhonda, your statement regarding AFNOR and ISO indicates a basic misunderstanding of essential oil quality. Those organizations set essential oil standards for the perfumery and cosmetics industries, which have vastly different standards and objectives than the aromatherapy industry. Fragrance companies are concerned with aroma and not with therapeutic action of oils, and that is reflected in the way those standards were developed.

Please reread some of the comments made in various posts below, so you have a better understanding of what CPTG and GCMS actually mean.

looking for high quality oils go to Hands on Aromatherapy. I have been buying from this company since 1993.

Tina, what is your website? I may be able to help.

Thanks for blogging. Tremendous information regarding aromatherapy. I would like to further suggest drops of lemon oils into the water for aromatherapy bath. It also helpful for complete relaxation to your whole body.

An aromatherapy bath before going to work could get you prepared for a nice soft as well as easy-to-cope-with-stress present.  To end the need for caffeine, try an inspirational oil for instance lemon or geranium oil. It is simplest to add mostly warm water after which add cool water until the tub is a great deal hotter than skin setting, but not uncomfortably warm. Use of aromatherapy bath is more helpful to reduce stress of your body and make you feel better for your whole day.

Aromaceuticals has posted a fall schedule of on site classes, from beginner to advanced. Learn from a nationally registered clinical aromatherapist and recognized expert in the field. Please visit the website for class dates, detailed descriptions and more.

Hi. I'm new to aromatherapy and have a few questions about a brand of essential oils. I've been using lotus touch essential oils but there are a few oils that I would like that they are either always out of or just don't have. I would also like to buy more local. I ran across this site near where I live and was wondering if any of you have used this brand and if it is any good. Even though I would like to buy more local, I also want the best essential oils I can get. Have any of you tried them?

Michelle, it's a good idea to have several high quality suppliers on whom you rely, since no one has the same product line, and the industry does experience shortages of various oils from time to time.

I'd like to invite you to visit my site at aromaceuticals.com and check it out. Since 2000, I have been dealing primarily with complementary health providers and hospitals, providing high-integrity essential oils and aromatherapy supplies. All oils are backed by certificate of analysis so you know you're getting the real deal. Unlike many companies, Aromaceuticals is owned and operated by a nationally registered clinician... I know my oils in and out and am a stickler for quality, since I use them in my private practice on a daily basis. If this resonates with you, you may contact me directly with any questions.
