The art of blending essential oils seems to be just that: an art! I believe that different topics within aromatherapy lend themselves to science on varying degrees. Let us digress for a moment and take a philosophical look at a couple of examples with regards to science and aromatherapy.

Example 1 - Flashpoints
If we look at the topic of essential oil flash points, it seems to be quite "scientific".
1. Heat oil "x" until it flashes into a vapor.
2. Record the temperature at which vaporization occured.

Example 2 - Prices
If we look at the topic of essential oil prices, it seems to be somewhat "scientific" in nature. Let's use Sandalwood oil as an example.

Natural Factors
1. Sandalwood trees only grow in certain places in the world.
2. Each tree grows at a fairly "fixed" rate.
3. There are only "x" number of trees that can be harvested each year.
4. Only so much oil can be extracted from the wood of each tree.
5. What's the age of the oil? (This should affect price!)
Human Factors
1. Is the oil synthetic or authentic and genuine?
2. Is the country where the trees grow politically open to sell them?
3. Was the oil steam distilled or solvent extracted?
4. Is the tree pesticide free and GMO (does this exist?) free?
5. How much profit margin is the seller trying to make?

The "Natural Factors" are somewhat "scientific" while the "Human Factors" tend to give us a little fluctuation (bit ironic - usually its the other way around...). However, once we have covered all of those points, generally speaking (assuming non-synthetics), the price of Sandalwood oil is usually "expensive". By that I mean that its going to cost substantially more money than a "cheap" essential oil such as Lemon or Tea Tree.

Example 3 - Blends With
The topic of "Blends With" or "Blends Well With" seems to be somewhat "scientific" at best. Over the years I have seen numerous books and websites showing lists of oils that blend well with one particular oil: Lavender oil blends well with Peppermint, Thyme, and Sage, for example. This is all well and great except I have almost never seen an explanation as to why they blend so nicely! On occasion an author may say the scents jive well together or the therapeutic property of one enhances the therapeutic property of the other. However, these explanations often tend to sound more poetic in nature than "scientific".

I suspect that each author has their own personal beliefs as to why oil "x" blends nicely with oil "y". Perhaps its because of their own personal experience or maybe something they read, or maybe something they were taught. I don't know. All I know is that when a person goes out to research the "Blends Well With" catagory for Lavender essential oil, after about 17 hours of digging around I can usually conclude that it blends well with just about anything including fried eggs, bubble bath soap, dog food, and motor oil!

So, instead of chasing around answers that don't seem to exist in regards to "Blends Well With" I have decided not to pursue this particular page of lists. Instead, I leave it up to you, the reader. If you think that botanical family is important when blending an oil then click on Lamiaceae (for example) and you will see the other oils that are in the same family as Lavender. If you think that chemical constituents are an important factor when blending then click on one, say Limonene for example, and you will see the other oils that also have that chemical constituent (please see Synergistic Effect of Essential Oils on Muscle Tissue for more on this subject). If you think that "type of scent" is important when blending an oil then perhaps my list of Scents will be helpful (however, classifying scent is very "non-scientific" in my opinion). Or, perhaps you would be interested in the scent classification of Carl Linnaeus in his book titled Odores Medicamentorum. In the words of E.J. Parry, 1945 - "There have been numerous attempts at the classification of odors, all of which have been empirical and useless and most of which have been childish and absurd." -- Not exactly my sentiment but it is one view on the subject...

If you think that an oil's note is important when blending (most authors believe so) then click on Notes and you will easily be able to see which oils are base notes, middle notes, and top notes.

Hopefully this page has been helpful. If you know of any "scientific" reasons as to why oil "x" blends well with oil "y" then send me a note. I would be interested to hear about it!
