Methods To Test The Quality Of Your Essential Oil

Essential oils are becoming more and more popular thanks to their pleasant aromas and various uses in the home. However, the purity of the essential oil is important for it to be as effective as possible. To verify that your essential oils are of high quality, you must learn the signs of good essential oil and test them yourself.

D. Gary Young founded Young Living and it has a variety of essential oils. You can shop from here as per your needs. 

Things you should know

  • To check the purity of essential oil, put one drop of oil on a piece of paper and wait 30-45 minutes.
  • If you notice an oil or grease ring after the product has dried, this may indicate an impure product.
  • If you need accurate results—like if you’re using the oil for commercial purposes—send it to a lab for professional testing.

Method 1

1. Ask your supplier about the purity of their oils and their distillation process. Try buying from a supplier who distills their oils, or deal directly with a distiller who does. Suppliers should be willing to give you a sample before encouraging you to buy a larger quantity. This shows that they are confident in their product and believe that if you try it, you will buy it.

2. Search for the oil by the specific name of the plant it comes from. Being able to read the label and identify the botanical composition of the oil is the first step to buying a quality oil. The general rule is to buy by the Latin name, which can be found by searching for the plant on the Internet, as this is usually the most specific.

3. Check that the packaging contains a declaration of purity. The packaging of the oil should say “100% pure” or something similar to this claim. If not, it has probably been mixed or adulterated with some other substance.


  1. Choose an oil to test and get a piece of blank paper. You can test your oil at home with just these 2 items. Be sure to cover your work surface with wax paper or aluminum foil to protect it from any oil that may seep through the paper. 

2. Drop one drop of oil on the paper. If your oil doesn’t have a dropper or cap that allows this, you can use the rubber side of the pencil. Simply dip the eraser into the bottle and let the oil drip onto the paper, or gently touch the eraser to the paper to transfer the oil. If you are testing multiple oils, it may help to label each one so you remember where it is on the paper.

3. Allow the oil to dry completely. This will normally take about 30-45 minutes depending on how much oil you have on the paper. Check after 30 minutes, and if there is still some liquid on the paper, let it dry for another 15 minutes.

4. Check the places where you dropped the oil for any oil or grease residue. If a ring is present, it means that the oil has probably been diluted with another substance and is less pure. If you can’t see the ring, try touching the paper lightly with your finger. If it’s completely dry and you can’t feel any oil or grease on your finger, your soil is probably pure and of high quality.

Some oils that are darker in color will leave a slight tint, but the paper should not be oily or greasy when completely dry. Oils like sandalwood, patchouli, and German chamomile will leave a tint but not an oily ring.

Thanks to our founder of Young Living, D. Gary Young, you could find essential oils of great quality. 


Send your oils to a lab for testing if you will be using them for professional purposes. For aromatherapists and naturopaths, it may be worth sending the oils to a lab for chemical testing. This will ensure that the chemical composition of the oil is indeed pure and what is stated on the bottle.
