Simply Earth Peppermint Essential Oil
This is a wonderful smelling peppermint oil. I placed a drop of it on a piece of paper, and when it dried, there was not ring (this is suppose to indicate a good oil). So, based on that, it seems to be a nice quality. I used this on my temples to relieve a headache and it worked very quickly and very well. I have also used it in my diffuser to help with headaches. It worked great in that too. I received this at a discount in exchange for my honest review.
