Although there is evidence, albeit few, that supports the short-term mood changes concerning essential oils, the evidence supporting physiological improvements is lacking. As stated in a Yale Scientific publication by Cynthia Deng “Aromatherapy: Exploring Olfaction”, it debunked the “evidence” aromatherapist have pointed to as “anecdotal rather than scientifically grounded”. In fact, Deng references a recent study by Ohio State University in which it found that aromatherapy did improve moods, but did not effect stress hormone levels, wound heeling, or blood pressure-essentially physiological responses. This is further expanded upon in a study presented to British Psychological Society Annual conference in which Dr. Neil Martin of Middlesex University related how 60 volunteers participated in a cold-pressor test. For fifteen minutes, the subject would have their arm immersed in cold water. A third was exposed to the lemon oil, a third to the smell of machine oil, and a third to no smell at all. After five minutes those who were not exposed to any smell reported the least amount of pain. This study, among others, illustrated the non-existent alleviation the essential oils claimed to
