To complement the MASSAGE Magazine column, “Aromatherapy for Massage Therapists: An Introduction to Blending,” by Dorene Petersen, in the March 2012 issue. Article summary: Before blending your essential oils, it is important to think about your goal. If your goal is natural, aromatic perfumery, selection of your aroma notes will be different than if you are blending therapeutically for clinical aromatherapy purposes. That is not to say the two are mutually exclusive; however, you will likely take a different approach for each.
