There was a time when all perfumes were made with natural ingredients. But by the turn of the 20th Century laboratories began synthesizing scents to replace essential oils. This was to reduce costs and guarantee uniformity. But the chemical composition of natural oils cannot be synthetically duplicated, especially such complex and delicate oils as rose and jasmine. Many people believe that it is the synthetic chemicals found in many commercial perfumes that contributes to the increasing incidence of allergies and other negative reactions.
