Aromatherapy has no effect on the immune system, pain sensitivity and speed of the healing process. This is the conclusion of researchers at Ohio State University, who studied the effects of aromas of lemon and lavender oil in healthy volunteers drawn. For three days, 56 men and women under the nose of the cotton ball in lemon, lavender oil or distilled water soaked secured. All participants regularly measured blood pressure and heart rate, and blood samples were taken for analysis. In order to assess their attitudes conducted special psychological tests. The rate of wound healing was assessed by a test with a strip of adhesive tape, which remained after the removal of small defects of the epithelium. The sensitivity to pain volunteers determine feet immersed in ice water. To examine the effect of aromatherapy on the immunity of the head of the study Janice Kaykolt-Glaser (Janice Kiecolt-Glaser) and her colleagues assessed the measured values of interleukin 6 and 10 in the blood of the participants, and the effect on the endocrine system has been in the concentration fluctuations evaluated stress hormones - cortisol, norepinephrine and other catecholamines. It was found that aromatherapy had no effect on the level of stress hormones and immune factors, has no analgesic effect and accelerate the wound healing. The only positive effect that is able to fix - improve mood influenced lemon (not lavender) oil. "The human body is a very complicated mechanism, and if someone feels better when you aromatherapy, we are not convincing. However, so far we have failed to reveal any physiological effects of essential oils, "- said Professor William Malarki (William Malarkey) The study was published in the journal Psychoneuroendocrinology..
