One of the most fun parts of my aromatherapy training has been learning how to blend essential oils.

Even though I had used essential oils for years, I was afraid to get too adventurous with making my own blends.  Which is a crying shame because now that I’ve learned how I love it.

It’s very gratifying to sit down and pinpoint an exact need and then tailor a synergy just for that.  I’ve been amazed at the results that custom blending has.  It really is a helpful skill to have.

That’s why I want to share how to blend essential oils with you!

Under the Influence of Oils

Are you ready?  Let’s go!

How to blend essential oils:

Step 1:  Decide what type of blend you want to create

Before you sit down and start dripping essential oils into a bottle, you should carefully consider the purpose of your new blend.

Think about:

  • Who is the blend for?
  • What do you want the blend to do exactly?
  • What are other factors going on in the life of the person who will use the blend?

So, in this post, I’m going to be creating a blend for myself.  My blend will help me get a good night’s sleep.  I also have a hard time shutting my brain off at night.  I will want to choose oils that both help me sleep and relax my mind.

Step 2: Choose your oils carefully

Once you know the purpose for your blend, you need to choose your oils.

I suggest considering a few things:

  1. Choose between two and five single essential oils.  Blending more than five is incredibly tricky.
  2. Make sure your essential oils complement each other and support the purpose of your blend.  You don’t want to choose any oils with properties that would conflict with the purpose of your blend.  For example, I wouldn’t want to put any oils in my blend that would have a stimulating aroma.
  3. Don’t try to blend pre-blended oils.  I consider blends (or synergies) to be finished products.  Blending them together can produce unpredictable results.

Not sure which oils to use?

Make sure to look through your reference book to find oils that will work well together.   If you need some help finding oils that complement each other check out my blending pairing chart below.  It gives some oils to consider.

Step 3: Test the aroma

After you’ve picked your oils, you need to smell them together before you start mixing.  After all, if the aroma doesn’t work, then you won’t want to waste your oils.

The easiest way to see if the oils will work together is this:

  1. Remove the cap from each oil.
  2. Hold the bottles in both hands, with the tops at about the same height.
  3. Waft the bottles back and forth underneath your nose a few times.
  4. Decide if you think the oils smell OK together.

Some people will tell you that a blend or synergy doesn’t have to smell good to work.  They are right, but let me ask you: what would you rather use, a blend that smelled great or a blend that smelled terrible?

I know which one I’d pick!

If you don’t think the oils smell right together try swapping out the one that seems out-of-place.  See if changing that oil for another helps the combination smell better.

If you’re making your blend or synergy for someone else, try having them smell the oils before you combine them.  That way you’ll know they enjoy the aroma before you try to get them to use it.

Step 4: Blend using blending factors

Blending is as much of an art as it is a science.  However, I don’t recommend just mixing things together at random.  That’s why once I’ve chosen my oils I use blending factors to determine the proportion I will use of each.

Blending factors rank on a 1 to 10 scale.  1 is for oils with intense aromas and 10 is for oils with milder aromas.  When creating a blend I use as many drops as the blending factor for each oil to start.

Using the chart you can download below, I determined that the blending factors for my chosen oils are:

  • Lavender (Lavandula angustifolia)-7
  • Cedarwood (Cedrus atlantica)-7 to 8
  • Ylang Ylang (Cananga odorata)-4

So I put 7 drops of Lavender, 7 drops of Cedarwood, and 4 drops of Ylang Ylang into a clean, recycled oil bottle.  You should always blend in glass containers, not plastic.  Essential oils seem to come together better when blended in glass.  When I don’t use a recycled bottle to blend, I love to use this cute little beaker set!  It makes me feel sciency.  Sciency is a word, right?

Step 5: Adjust for aroma and balance

Once you’ve measured out your oils, give them a swirl in the container.  You may even have to gently shake it for a few seconds.  Then take the container and hold it under your nose to see if you like the aroma.

Ideally, you shouldn’t be able to pick out the aroma of any single oil.  The oils should all have combined into a new aroma.  If your blend seems out of balance, try adjusting it one drop at a time with the other oils that stand out less.  Adjust until you like the aroma, taking care to write it all down.

Once you like the way it smells, you can use the formula to double, triple or even more your blend.

Make sure to label your new blend before use and storing.
