The other brands, while cheap, seem really watered down and have very “off” aromas. It worries me to use them because I suspect there are some solvents or chemicals used. They do not claim therapeutic grade. One bottle of Rocky Mountain’s immune boosting blend only lasted me a week when diffusing it, but a bottle of doTERRA’s comparable blend, OnGuard, lasted me several months. The difference in price can seem dramatic, but when you have to use 10 drops of one oil to get the same effects of 1 drop of another… they even out.
Hey! Sorry to be commenting on such an old post, I was googling and found you. =) You have a lot of helpful information posted, I really appreciate it! I am a nursing student and I’ve just started to use essential oils for studying and test taxing anxiety. I am using lavender and rosemary because I’ve read a lot of research on these and they seem to be scientifically proven to help with testing. I also have ADHD and of course like all nursing students, a ton of test taking anxiety. I am wondering if I could combine the two oils to help me with my exams? If so what would your ratio recommendation be? The rosemary alone seems to help me concentrate a lot (probably as much as my adderall) but I feel more anxious when using it (also like when I take my adderall). The lavender alone makes me so relaxed I’m a little on the fuzzy side. I have done both of these with the diffuser and applying topically with fractioned coconut oil. When I apply topically I make a rollerball with 10mL of fractioned coconut oil and 20 drops of essential oil. Any advice or tips you can give would be greatly appreciated!

Hey, Rachel. It looks like you may have too many top note EOs in your blend which is why you’re not getting that long-lasting scent from it. Rosemary is the only oil you listed that is a middle note, but it’s also considered a bit of a top note too. In all the blending formulas, the middle notes make up the largest portion of your blend with top notes coming in second and base notes coming in last as they mainly ground or stabalize your blend. If I were you, I would go through the process again, adding in more middle note oils and maybe taking out some top note oils. Or, you could always find some middle note oils that fit with the purpose of your blend and blend well with the oils you’re already using. In that case, all you’d need to do would be to adjust the amounts of each oil in the final blend (using the suggested formulas) so that your middle note oils make up the largest portion of the blend. Hope that helps! PS… There are also some essential oils that stimulate nerves that allow you to smell them once and then you can no longer smell them until the nerves are destimulated. I can’t remember which exact EOs that do that, but I read about it from an aromatherapist a while back. I’ve not looked into it much, but I thought that was interesting.
Hello I just recently got a divorce. And for a couple weeks could not sleep so the dr. put me on sleeping medicine I do not want to be on them and I was wondering if you could tell me what would be the best essential oils that I could use for falling asleep I use a necklace infuser. By using that would that work or should I apply to the body like you have said in this site. I use lemon oil for depression. What would you have me used to sleep thank you so much for your helping and I really appreciate your time and knowledge on helping me learn thank you.

I also really enjoyed your information on blending. When I first started blending oils I didn’t know much so I would muscle test which ones I needed to use and in what quantity. It’s interesting as I am learning more of the “science” behind it, and I go back to my blend recipes and see how it all played out with the top, middle, and base notes, all in the correct quantities. It’s actually really fun to see. I am enjoying learning more, which makes me realize how much I don’t know!! 🙂

Honestly Tori, I’m new to using roller bottles. I normally just put my essential oil blends in a bottle with a dropper top and use them that way, but I’ve recently gotten some roller bottles and started trying them out. My only thought would be that moisture got into the bottle somehow and it’s trapped in there by the roller ball. Other than that I’m no help. I’m so sorry!


Hi there – thanks for a great article, I am just starting out in using essential oils and this has been really helpful. I have just made my first batch up today of blends (Relaxing: lavender, bergamot & rosewood. And insect repellent: lavender, peppermint & rosewood. I don’t have a large stock on EO’s yet so limited to what I can use at the moment). However I am little stumped regarding the dilution rates? In your article you gave a 10% and 20%, are these okay to use on the skin? I read on another page that a 2% dilution should be used on the skin? So more like 1 drop of essential oil blend to 4 tsp of carrier oil. Which is correct please? Also, what dilution rate would you recommend on young children? Thanks 🙂

Oh good for you! It’s tough picking your oils, but base notes do help your smells to last longer. Patchouli, sandalwood, and vanilla are some of my favorite base notes. I’m not sure how great each of those would smell with the oils you used, but you’d have to test it out and see. Another thing I’ve learned is that when you’re making something, it will always smell stronger when you’re making it than when you put it on so sometimes you need to add a good bit more of the oils for good measure. Hope that helps!
