"I am sensitive to perfume and, at first, I would not try the essential oils. I was concerned about my sensitivity to perfumes. At the urging of a good friend, I finally tried the oils. I am so glad I did. I had to go slow in the beginning to allow my system to release toxins. I did go through a cleansing, however, I could tell that it was different from my reactions to perfume. I now have no problem with any of the oils. I recently went into a store that sold the competition's essential oils and within a few minutes my eyes were watering and my nose running. I, myself, went running from the store. I had to get out immediately! I have realized that my reaction is not to the plant essences, but to the chemicals used to process the competition's products. However, I do not have a problem with Grade A 100% Pure Organic essential oil products because of their purity. I feel that it is important for people with food allergies or sensitivities to things like perfume, to go slow and focus on detoxing in the beginning. Cleansing reactions are possible, however, the reaction is not to the essential oils, but to the toxins in your body. Once my body was cleansed, I felt better than I have ever felt. Adding the essential oils to my daily program has increased the effectiveness of my nutrition program."
