I was going on day two of a migraine and my medications were not doing their jobs properly to the point that I was taking the maximum amount allowed in 24 hours. My sisters recommended I try an essential oil mix, so I ordered this one and it arrived a day later (migraine still there). I'm not sure if it was a placebo effect or what, but this definitely did a better job than my medications did. It dulled the migraine to a tolerable point for 1-2 hours at a time and there are no issues with reapplying if you need to! It's a pretty strong smell, but a nice one. I put little dabs on my temples, behind my ears, and at the nape of my neck. I'm going to continue to use it.
