This blending ratio doesn’t have a drop limit, but keep in mind that you want your blend to stay small so you don’t waste your oils (in case you don’t like it). You’ll be keeping track of your essential oils and drops on paper. This blending ratio works well with pure combinations (essential oils from one category) and mixed combinations (essential oils from complementary categories).

This makes smell unique among our senses. Information we take in from our other senses travels first to another region of the brain, the thalamus, which acts as a relay station, passing along sensory data to the other parts of the brain that produce our sensory perceptions. Only smell moves directly to the brain’s emotion and memory center. That’s why those memories you associate with the scent of garden roses, or banana bread baking in the oven, come on so quickly and so strongly.

I’m a massage therapist and also a user of EOs. I really enjoyed reading this. I found it to be very helpful in understanding EOs and how to blend them by notes and by and by categories. This has been the most in depth I have seen anyone get into usage and blending. I apreciate how positive you are towards all brands of oils. I have bookmarked your page and will be back for more information.
I really enjoy Lea’s website too! One thing I recently learned about the 3rd party testing she had done though, was it may not be very reliable. She chose a chemist in France who used outdated testing equipment simply because it was the cheapest. And although I greatly appreciate her knowledge, she gets very defensive and on the verge of rude at times in the comments. I also know she doesn’t appreciate learning that isn’t taught by a certified aroma therapist.
If it were me EYG, I’d Google “safe essential oils for dogs” and get a list to go by. Then I’d Google “bug repelling essential oils” and compare the two lists. Cross off any EOs on the bug repellant list that aren’t safe for dogs. Next, I’d put the oils you have left into their notes and categories and try to find 3-4 bug repelling oils that can be paired together and still smell nice and well-rounded. You can combine these EOs together using the percentage rule mentioned in the post and label it with “bug repellant EOs for dog”. When you’re ready to use it, mix it into your carrier oil at the appropriate dilution and you should be good to go. Hope that helps!
