Do your homework before you begin diluting essential oils!

Simply diluting an essential oil is not necessarily going to make it safe to apply to the skin! Research each specific essential oil you plan to use first. Many essential oils will be very safe and effective when properly diluted in a carrier oil.

Don’t let similar names of essential oils confuse you.

Getting the name right matters. In terms of medicinal properties, safe application and expense.

-The Latin Binomial will ensure you have the plant oil you mean to use.

Because: Chamomiles. I can think of 3 completely different species, all called Chamomile.

All very different.

Because: Eucalyptus. Eucalyptus Radiata and Eucalyptus globulus are also not the same.

For example, one of these is safe and amazing for use on little kiddos.


This occurs with plants of the same species, chosen for chemical composition favoring a good deal more of this constituent or that. Often Rosemary will be differentiated by chemotype. Rosemary Cineoles, Rosemary Verbenone, and so on. Both Rosemary officinalis.

What else to consider:

Find a reputable source for descriptions of essential oils. Here you should find useful information about the awesome things essential oil can do for mind, body and skin. Also what stuff to look out for associated with the particular oil. Like photosensitivity with Bergamot and citrus, skin rash and burns associated with cinnamon, and neurotoxicity from ingesting thujones in Mugwort, Sage and a few others.
Keep in mind the age of and any health conditions of person the essential oil blend is intended for. Pregnant or nursing? Asthma, heart conditions, autoimmune disease, so on? Some oils may come with precautions for use in such individuals.

A final google search:

Just to be certain, please. This dilution chart is meant to be used with essential oils you have already determined to be safe for your purposes. These dilutions are appropriate for topical use only.

A carrier oil is one or more fixed oils that will be the vessel which carries your essential oil blend gracefully into the body.

Carrier oils have many nourishing and healing properties of their own. I chose carrier oils that are likely to support or enhance the healing purpose of each blend. I try to factor in cost and availability as well.
My favorite carrier oils include Jojoba, Coconut Oil, Olive Oil, Walnut Oil, Sweet Almond Oil, Shea and Cocoa Butter. They are used alone or easily mixed up in whatever proportions you like.
You can even incorporate one or more “Fancy” oils in your carrier oil blend. These are rich in nutrients like essential fatty acids and are intensive healers. These “fancy” oils, altogether, should make up no more than 10% of carrier oil.
Fancy Oils I love are Evening Primrose, Borage Oil, Argan Oil and Tamanu Oil. There are many more of these, also each with a unique healing profile.

Once your oils are chosen,

Step by step process to make the test batch

  1. I like to prepare a test batch from 15 mL carrier oil, then add essential oils. I do this to be sure the smell is agreeable and that the blend doesn’t cause an adverse skin reaction.
  2. Make any necessary adjustments.
  3. Prepare a practical amount of carrier.*
  4. Determine Total drops of essential oil to add to the carrier.
  5. Measure out each essential oil, then add to carrier oil.
  6. Stir it up, Viola!

*(One ounce of oil for sore muscles may not last a grown person more than a few days right? And of course if putting just a small amount on baby’s foot maybe not 8 full ounces)

As obvious as some of this information seems, many of these considerations were not always obvious to me. Much information I have included comes directly from what I learned from experience and making mistakes. I was always so disappointed when precious ingredients, not to mention my time and energy went to waste.
