Alright so I haven’t got a high tech lab in the shed at the bottom of my garden, but come on guys give a girl a break I’m trying my best. Essential oil testing at home couldn’t be easier with these simple tests I list below. They are great to discover if your oils have been watered down, contaminated with chemicals or filled with carrier oils. 

Some brands have their products third-party tested and offer these test results online. I would always look for this when you’re choosing an essential oil brand to buy. 

Welcome to my lab…

Test #1 Company Background Check

With my Sherlock hat and magnifying glass out, I roll my sleeves up and get into some serious deep digging.

I begin by scrolling through their website and other articles written about the company. The main objective I have is uncovering information on where their oils are sourced and if they are using ethical and sustainable practices.

How long the company has been around can also add a layer of trust. Especially if they are grandaddies in the essential oil world, with lots of consumer reviews behind them.

Test #2 Packaging

The bottle should be amber in color, as it has the ability to block most UV rays. The material should be glass, as essential oils are corrosive enough to break down plastic over time. 

I look out for an orifice reducer at the top of the bottle, or else I’ll be pouring the oil out, rather than delicately dropping a few drops of the precious liquid out.

The latin name of the plant should be written on the bottles label. You may be thinking why? Lemon is obviously lemon. Well, different plants can sometimes share the same common name. Let’s take Chamomile for instance, there are several different types of this plant. This can be highly problematic because plants sharing the same common name don’t necessarily share the same therapeutic properties, benefits or contraindications.

Test #3 Paper test

This is the test where I discover if there are any added oils that are not an essential oil.

Using cotton rag paper (not just your standard printer paper, as they have been chemically bleached and may react with your essential oil.) I got my rag paper from this Etsy shop if you’re stuck on where to buy some.

I place 1 drop of essential oil on the paper, then go and make a nice cup of tea and set my timer for 20 minutes. If I come back and nothing is there it means alcohol has been used as a carrier. I’m hoping to see a gradual fade in the paper, not this quickly.

When I check back after 12 hours nothing should be left on the paper. The only time I should see a tint on the paper is if I’m using lemon as that is slightly yellow when dry. Other than that if any marking is left that means a carrier oil has been used.

Test #4 Freezer Test

Easiest testing award goes to this! Literally just pop the essential oil in the freezer. If it freezes it has water in it, simple. Make sure you use new oils with closed lids though, as moisture from the air could contribute to it having some water inside.

No food in the freezer but that’s ok, at least we’ve got essential oils!

Test #5 Smell Test

Firstly I like to take a big deep inhale from the bottle and see what gets those nostrils tingling. I’ll then put a drop on my hand and take another deep inhale, as the smell changes when it comes in contact with skin. I’ll wait an hour and have one last final sniff and see how it smells.

I do realise that this test can be subjective, but some of the things I ask myself when smelling the oils are:

  1. Do I get a headache afterwards?
  2. Does it smell sweet?
  3. Does it smell earthy?
  4. Does it smell floral?
  5. Does it smell perfumey?
  6. Does it smell like the plant it came from? Or does it smell more like the fragrance or flavoring?

Test #6 Blend Test

This is when mad scientist Sara comes out! It’s all about combining essential oils and creating a chemical reaction.

Firstly I take a new dropper bottle, then take three essential oils and drop 10 drops of each into your new dropper bottle. I then leave them for 24 hours and wait.

When I come back in 24 hours I put a couple of drops on my hand and take a big sniff. I cross my fingers that nothing is off with the smell or else I’m knocked back a few steps as my nostrils are on fire.

If it does smell off I know that extra chemicals have been added to the oil, into the bin they go.

Test #7 Healing Properties

So this is the big one, the big don, the cream of the crop, the crème de la crème. I ask myself, is this oil actually helping me? 

This test happens as and when myself or a family member needs some alignments fixed. 

I have used essential oils to get rid of blemishes and spots, reduce infected areas, calm the mind, ease foot ache, decrease bruising, get rid of congestion and much more. 

I will always update my articles when I have successfully treated something with essential oils.
