Just because you are able do something, doesn't mean you should. With that said, I want to caution you regarding essential oil recipes you find online. Unless it is coming from an aromatherapist with extensive training and/or an affiliation to NAHA (National Association of Holistic Aromatherapy) or AIA (Association of International Aromatherapists), chances are it is unsafe and should not be followed. These organizations "vet" their members to be who they say they are.
Let's look at some I found after searching for about 5 minutes. I have removed any website names and information as to not embarrass anyone or cause problems.
