CPTG – doTerra ; The best quality label for oils ?

CPTG’s promotion found on Google Image (1)

Definitions :

doTerra : MLM company selling -mostly- essential oils.
MLM : multi-level marketing.
CPTG :Certified Pure Tested Grade” (3) or “Certified Pure Therapeutic Grade” (2) (4). Seems like doTerre themselves aren’t sure about their own label.
Pure : without pesticides, herbicides or any kind of additives.
Therapeutic : curative, that heals.


For those who want a quick answer, doTerra is using its own quality label, “CPTG“, claiming it is way better than any kind of national / international test about oils.
Their label being their own, the objectivity is questionnable.
They claim that “multiple” labs are verifying the CPTG but we can easily find out there’s only one that does : “APRC“, Aromatic Plant Research Center.
APRC is led by “scientists” who are heavily linked to doTerra. doTerra is also the CLIENT of the APRC, which means the lab is paid by the company to “test” their products… Questionnable again.
APRC has been founded by the same law group used by doTerra for their legal mark deposits or even when taking other companies to court : “TraskBritt“, that’s an other link.
Even with all these links, we can find that CPTG only guarantees superficial and non factual characteristics about oils.
Also, doTerra never proved their oils to have any therapeutic effects unless from their “Third party labs” that you now know as linked to them.

If you want more details, here is the whole research.

Research :


Let’s talk about science from doTerra.

They’re using it for their label CPTG. But, what is CPTG ?


doTerra says that CPTG is “Certified Pure Therapeutic Grade” or “Certified Pure Tested Grade” (seems like it depends on their mood). This label is owned by them and is supposed to verify their oil quality with scientific proofs.

So basically they are using their own label to prove that their oils are “better” than any other oil in the market…

But hey, look, it’s cool, they say CPTG is tested by “Third parties labs”

Even before checking those labs, let’s see what guarantees this label

We are not going to stop on their scientific tests as our dear Author isn’t qualified to check if it’s a correct way to do it or not. (we’re still open to editing the post if someone is able to provide us informations about it)

Here is one of the multiple explications about doTerra’s CPTG :


“CPTG Certified Pure Therapeutic Grade is a doTerra Holdings, LLC’s brand standing for norms on quality’s evaluation and materials’ control. CPTG’s testing protocols require third parties laboratories in terms of normalisation and quality’s control. CPTG protocol isn’t administrated by government or regulatory agencies and doesn’t imply any approbation on doTerra’s products.”

CPTG protocol isn’t administrated by government or regulatory agencies and doesn’t imply any approbation on doTerra’s products.

Seems a very serious science’s stuff, isn’t it ?

But again, don’t worry ! Some doTerra’s affiliated will tell you that “Without an accepted standard for essential oil quality, doTERRA created its own”


“Because organic certification varies so much from one country to another, it is not possible to acquire all essential oils under organic status. So doTERRA created their own quality control standards that exceed the industry standards for organic/therapeutic and they decided to call it CPTG  (Certified Pure Therapeutic Grade).”

So.. they didn’t pass national controls but they claim that THEIR label makes their oils way better than any other on the market.

Plus, there are honestly few reasons for a company to put themselves under more restrictions than a state would impose them, so we can even more doubt of their false kindness.

So, what else does Rebecca claim about CPTG on her website ?


Well, it seems like we can find pesticides, herbicides and even unlabeled species in their oils… We thought it was called a Certified Pure Tested Grade.

By the way, as it’s also called Certified Pure Therapeutic Grade, we can quickly talk about the fact that they use this term but its meaning can be somehow fuzzy.


It can mean “curative” or simply “having a beneficial effect”. We also recommend you to watch carefully on doTerra’s website to see some hidden mentions about this, they clearly claim to have “curative” oils but then add below their page that they’re not verified by the Food and Drug Administration. How cute from them. We will maybe write an other article to debunk their claims on their oils, complementing this one.


Well so, pure but potentially with pesticides, right ?

Maybe all this is just a misunderstanding, let’s see what really guarantees this CPTG label.

  • Compounds carefully extracted

Yeah..? So what ?

  • No fillers or artificial ingredients

Ok let me remind you something quickly…


  • Methods to ensure oils are free of any contaminants

Food domain :
United Nations Organisation for food and agriculture :
“Any substance that is not intentionally added to food, but is founded in it as a production’s residue […]”

So, what’s a contaminants ?

On the Wikipedia French page (seemed like no one translated it yet), we have a definition from the UN. It says : “Any substance that is not intentionally added to food, but is founded in it as a production’s residue”

And yes, essential oils ARE food if we refer to French Health Department, as they are dietary supplement.


Whats is a dietary supplement ?
Dietary supplement are defined as “food […]”

So, stop us if we’re wrong but, pesticides, it’s intentional or no ? We guess that no, so this point about “no contaminant” seems totally wrong.

  • Gently and skillfully distilled

Cool. What does that mean ? Did they take smooth gloves and kiss their plants ?

  • Additional rigorous quality testing

Which ones ?

  • Patiently harvested

Can you tell me more about that ? What does that change ?

  • Product is guaranteed

Cool it’s guaranteed ! Wait… What’s the guarantee about ?

We also can find this :


So they are also paying a lot of attention to :

  • Sourcing
  • Country/soil of origin
  • What is sprayed on a field or added to the soil
  • Distillation processes
  • Uses of solvents and chemicals for extraction
  • Temperature

Cool, but what’s the purpose of it ? What does that mean to “pay attention” ?

Nothing ?

All this seems to be very blurry.

Are you glad to know that your product is a CPTG certified one ?

No ?

But that’s not all. Do you member we talked about labs at the beginning ?

Let’s check these.

doTerra owns a website named “sourcetoyou.com” where we can find “THESE” “THIRD PARTIES” labs. Just saying, third parties means they are not linked doTerra.


So here it is. APRC, Aromatic Plant Research Center.

Just to be sure it’s really this lab that does verification for doTerra, let’s have a test on one of their products.


Here is the page we can use to make a test.

We can see this product is CPTG certified. So now let’s download the PDF.

Images are mostly blurred because of a Copyright.

Click on the image to see it clearly.
Click on the image to see it clearly.

At the bottom of the document, it’s written : “The analysis of this [product] lot revealed no contaminants or adulteration.” We just hope there’s no toxic stuff inside…

So we can see it’s clearly the APRC lab that gives us the result, as it’s also them who will give doTerras’s oil the CPTG label.

We can also see that doTerra is considered as a customer, for this lab. Which means doTerra directly pays the APRC to run the tests…

Note that we came from “Third party labS” to only “third party lab”.

So let’s see if we can find more informations about this THIRD PARTY lab (already linked with money but whatever).

But hopefully, APRC’s scientists won’t be linked with doTerra.


Check up on their executive board :

  • Aaron Sorensen

This guy is clean unless that he participated to a doTerra conference. So that’s a bit of proximity between them.

  • Prabodh Satyal

May seem clean too, but the guy is in some videos at doTerra’s conferences, like Aaron Sorensen. He is also a co-author on some study with Noura Dosoky (but we’ll see her below) https://www.researchgate.net/profile/Noura_Dosoky (list of co-authors on the right)

  • Anjanette DeCarlo

Wow she’s all clean ! Is it the beginning of trust between us and doTerra ?

  • Brian Lawrence

No Brian ! We had faith !

Here is Brian who is a Scientific Advisor for doTerra PLUS a Senior Research Scientist for APRC lab.

Well, seems like we can throw the “Third Party” part, right ?

  • William Setzer

William, you’re even worst. This is at the end of one of your “scientific” study.

“This work was carried out as part of the activities of the Aromatic Plant Research Center. (APRC, https://aromaticplant.org/). The authors are grateful to dōTERRA International (https://www.doterra.com/US/en) for financial support of the APRC.”

By the way its done with “Noura Dosoky”, and here she is :

  • Noura Dosoky

We have a great combo ! She made studies financed by doTerra FOR the APRC and she is doing some livestreams with the Founding Executive Sales & Marketing of doTerra.
Oh dear objectivity, where did you go ?


That’s funny because this Internet website also says that APRC is a third party lab and that no scientist is linked to doTerra.

We’re on the end of the subject. We’ll now just throw some facts and you’ll just make yourself an opinion of what you see.


We can see that APRC was registered by the APRC itself. Nothing much interesting here. But we can see who was the attorney.

It’s Krista Weber Powell, she works for TraskBritt which seem to be a lawyer’s office.

Can you guess for who she’s working too ?

Yup. doTerra. She registered all (or almost) their trademarks and she was their attorney for their court attacks.

If you’re curious, I’m giving you at the end of the article three sites to see it yourself. (6) (7) (8)

We can also quickly see that a guy named Mark A. Wolfert, working for TaskBritt, is also a Founding Executive and General Counsel for doTerra (https://www.zoominfo.com/p/Mark-Wolfert/1411940925).


To end all this, doTerra owns a charity association : HealingHands.

I have nothing more to say about it. Some of you will understand what it could mean.

So here we are :

CPTG’s label from doTerra : BULLSHIT SCIENCE.
