The Ultimate Guide to Buying Essential Oils: 10 Things You Need To Know

Everywhere you go you’ll find people and stores selling essential oils or essential oil-infused products. Essential oils have been gaining popularity and the industry is expected to reach over 11 billion dollars by 2022. 

Unfortunately, the essential oil industry remains unregulated which means we often don’t know what is truly inside those pretty fragrant bottles. In fact, there are certain must-knows that are hardly ever mentioned by (health food) stores… In this ultimate guide, I will walk you through the things you need to know before buying essential oils. 

Essential Oil Must-know #1 

Pure Essential Oils Are Often Not Actually Pure

When done right essential oils have amazing healthful properties. Most likely, you’ll have seen or bought essential oils with labels that say ‘pure’ or ‘all-natural’. I’m very sorry to say that most essential oils sold on the market are not 100% pure. This is possible because until now there are no regulations in place with regards to ingredients, purity, labels or practices.


A company can describe their essential oils as pure while they are actually altered, also known as adulteration, to enhance the smell or extend the shelf life. This is done by adding alcohol, synthetic aromas or synthetic chemicals. Another common way is to add lower quality versions of an oil to drive the cost down.

This happens a lot with lavender and there are many reports of fraudulent practices in the essential oil industry.  What is sad is that this is often denied and none of it can be found on the label…

Essential Oil Must-know #2 

Essential Oils Don’t Last Forever

They only last forever when certain additives like preservatives are used to extend the shelf life. The oils might technically still exist but you have to consider at what cost.  

I prefer to choose products that don’t carry harmful ingredients AND deteriorate naturally. When people claim that their purely natural oils last forever it is clear to me that they have been misled.


The truth is that while the oil may last in a sense that it just “exists” for a long time, most oils pure or otherwise will eventually go bad due to oxidation. This is unavoidable unless you could somehow store them in an oxygen-free atmosphere, which is basically impossible. 

Do yourself a favor. Stay away from people who claim these sort of things AND check the expiration date on the bottles. 

Essential Oil Must-know #3 

Therapeutic Grade Means Nothing 

There is no independent industry-wide certification of essential oils. This means any company can claim that its essential oils are therapeutic grade, clinical grade or whatever they decide to put on their bottles. 

The Food and Drug Administration has criteria for aromatherapy but the only thing that is truly regulated are the advertising claims by the Federal Trade Commission.  

Testing Standards

Some companies do have fantastic essential oils that live up to high standards. However, unless a company is completely transparent and can back up their claims like this one, they may not necessarily be true. The way to gain confidence is when a company uses third-party testing and does extensive testing of their oil batches using the following tests:    

  • Mass Spectrometry
  • Gas Chromatography
  • Organoleptic testing
  • Microbial testing
  • Fourier Transform Infrared spectroscopy
  • Chirality testing
  • Isotopic analysis
  • Heavy metal testing

Essential Oil Must-know #4 

Source Matters!

The quality of the plant material is determined by location, climate, altitude, times of harvest, and many more factors. In order to get the highest quality essential oil, it is necessary that the crops grow where they naturally thrive.   

Global Expertise

This is not an easy task because companies need expertise in sustainable and correct growing and distilling methods. They, therefore, need to rely on the local growers and distillers that are experts in their field.

So when you are looking for the best essential oils, one of the things to look for is to see whether the company harvests their oils globally.

This is NOT the same as outsourcing to farmers and distillers who may not share the company’s quality demands, which is why full transparency is so important.  

The essential oil company I work with works closely together with farmers and distillers in over 40 countries, which is incredible. 

Essential Oil Must-know #5 


I often hear people say “well I only buy organic, so I’m sure it’s one of the best.” I believed this to be true at first also. However, I’ve come to discover this is ineffective for concluding whether an essential oil is free of pesticides and other impurities.  

For example, if the organic farm is next to a heavily polluted area, the plants from your farm will likely be polluted too.  

Organic Certification

I also discovered that the largest essential oil company in the world doesn’t even carry an organic label. This is because each country requires a different certification requirement while most often the inspector never even visits the farm to verify that they are, in fact, growing organically. So having an organic label is not all it’s cracked up to be and you are often just paying for marketing.

What is more important is that a company has strict quality standards and can analytically prove that their essential oils do not contain pesticides, herbicides, fillers, synthetics, or added natural compounds.

Essential Oil Must-know #6 

Equal Prices For Different Oils = Major Red Flag

When looking at the plant as a whole, they are composed of only a small amount of essential oil—on average, just 1–5 percent of a plant’s total composition. Acquiring even just one bottle of essential oil requires an incredibly large amount of plant material.  

Each plant is different and because of that essential oils are sold for a range of prices. 

Price Depends On: 

  • The availability of the plant
  • The essential oil yield of the plant material
  • Cultivation methods
  • Harvesting
  • Methods for deriving the oil (require different amounts of time, effort, cost)

 Extraction Processes Vary 

If you are using essential oils to support your health needs, then you will want and need the best quality essential oils.

Quantity should never trump quality in the essential oil industry, but it often does.

I’ve seen different types of essential oils in health food stores that were of very similar prices and often super cheap. This is often a telling sign that you are not looking at high quality pure essential oils.

Essential Oil Comparison

Lavender essential oil is relatively a more affordable purchase because it is a very available plant and requires three pounds of lavender flowers to produce 15mL of essential oil.

This is contrary to rose oil which requires about 242,000 rose petals (or 105 pounds) to produce one 5ml bottle of rose oil.  Crazy!

Use Common Sense

It makes no sense to be able to buy a pure lavender essential oil for the same price as a pure rose essential oil. Nor does it make sense to get products that are 100% pure essential oil, and therefore very labor intensive, for extra low prices.

Extra tip: use each oil’s Latin Name. Without the Latin name, you can easily mistake one plant or essential oil for another.

Essential Oil Must-know #7 


With the rise in popularity of essential oils, companies are harvesting more plants, trees, fruits, and flowers than ever. Harvesting on such a massive scale not only endangers the plants but their growing environments and the animals that survive off those plants too.   


You may not be aware of it but Frankincense is a highly desired essential oil and is put in all sorts of skin care and other beauty products.

In 2016, an article by the Associated Press warned that Frankincense trees were being over-harvested and were under major threat. This has serious consequences for the local communities involved and the beauty & wellness industry and is requiring responsible companies to take the lead in caring for these trees.  

Sustainable Harvesting Best Practices

There are a number of things essential oil companies should do to sustainably harvest.

  • At-risk plants/trees should be assessed to prevent over-harvesting or tapping, and ensure harvesting seasons never exceed a specific time period to allow for the plants to recover and grow naturally.
  • Companies should work directly or at the very least provide fair wages to the harvesters, like how this company is doing it. This ensures that harvesters don’t over-harvest because they have a reliable income.
  • Companies do not violate the Lacey Act and the Endangered Species Act.

We love sustainable practices!

Essential Oil Must-know #8 

Using Oils Neat Is Not Always Best

Some companies sell neat oils as well as blended oils. Neat means that the oils aren’t diluted with a carrier oil, like coconut oil.  

This is important to know because essential oils are very potent and should always be used in a safe manner, which often means diluting when using on the skin. Especially with those that are considered “hot oils” like oregano, cinnamon, and clove essential oil, because undiluted they can cause damage to the skin.

Some people prefer to buy the oils pre-blended to save time or when they are applying them to sensitive skin or children. Depending on which oils I am using and for which goal I will either use them neat but most often I’ll dilute when using on the skin. It’s cheaper this way and just as effective!      

On your skin isn’t the only way to use essential oils! If you want to learn about what other types of uses there are, head on over to our essential oils for beginners guide.

Essential Oil Must-know #9 

Skin Irritations is NOT Detoxing

Oh man, I’ve heard this one so many times. It makes me mad to know there are people out there who are spreading this as the truth.

There is no positive explanation for any adverse reaction that natural products might cause us.

In fact, just because something is natural doesn’t mean it is good for us. There are plenty of ways that nature does not treat us kindly.

If you get an adverse reaction that means your skin is IRRITATED.

Start Slow

A rash or burn from an essential oil is basically your skin saying STOP what you are doing, now! This is why when using a new essential oil, we always recommend doing a patch test on a small area of skin to see how it will react.

Some Oil React With The Sun

Also, know that certain citrus essential oils react with the sun. This is called phototoxicity and is nothing to fear and perfectly normal. Make sure you don’t use citrus essential oils for at least 24 hours on the areas of the skin that are exposed to the sun (bergamot is 48h).

Essential oils are fat-soluble and for that reason, you won’t be able to wash them off with water. If you do end up getting a skin reaction or get some in your eyes, don’t use water but grab any plant-based oil like coconut oil, and use that to rub off the excess oil.

Remember, essential oils are very concentrated and potent. Let’s be mindful of that. Rather be safe than sorry.

Essential Oil Must-know #10 

Start With Basic Multi-Functional Oils

I say this because I see people have a good experience with a specific oil and then buying one or two random oils, that don’t have many functionalities. They end up not knowing what to use them for and only using them a few times a month during bathtime. Sound familiar?

Assuming they are of good quality, this is such a waste of money.

If you want to make the most out of essential oils I would recommend starting with the basics.  That means learning how to effectively use a limited number of basic essential oils.

I would suggest starting with Lavender, Lemon, Peppermint, Frankincense, Melaleuca, and Oregano. The company I use also offers a few blends that I find extremely helpful for beginner’s because you don’t have to buy expensive oils separately. These blends have tremendous benefits such as digestive, respiratory, immune, and muscle/joint support.  

Use Your Basic Essential Oils To:

  • Clean low/no-tox
  • Reduce stress & anxiety
  • Supporting day to day ailments like tummy upset, scrapes, cuts, congestion, colds, seasonal discomfort, muscle aches, trouble sleeping, bug bites, small burns, you name it.
  • Managing mood
  • Supporting a healthy work environment
  • Supporting exercise and yoga
  • Great for supporting kids physically and emotionally.
  • Oh, and of course for sniffing them and bathtime too!

Yaaaas!! Essential oils can do all of this and more. Sounds pretty good, right?!

The Last Thing You Should Know Before Buying Essential Oils

There are multiple companies in the world that produce pure essential oils. Finding those companies, however, is not always so easy.  

Another problem is that there are a lot of companies out there selling essential oils, but most of them do not have the ability (or sometimes even the desire) to do the necessary quality control before passing their oils on to their customers.  

The essential oil industry is massive and there is a lot of money to be made in it. I don’t see a problem in this as long as the companies are run ethically, sustainably, treat and educate their workers and customers REALLY well, and provide pure high-quality essential oils.  

Trust Your Own Instincts

In the end, I think it all comes down to who YOU trust. I will always strongly advice you to do your research and not just take my word for it. I’ve included a checklist for you below and in case you’re curious which oil brand I trust and use. 

This is my favorite essential oil company.
