I was listening to a public radio station while driving yesterday. The show featured fragrance used in every day products with a Professor Anne Steinemann of Washington Universtiy. What I found interesting is that fragrance reaches the reptile portion of the brain directly, bypassing the blood brain barrier much the same as alcohol but, through the olfactory system. The host said some nice things about the French perfumes as being less or not harmful, but the fragrances used in house hold products were scarry. Mentioned were the fragrances in laundry detergents. I will be getting the non scented from now on. If you are interested in Anne Steinemann's research you can google her name and go to the University of Washington web site for more detail in a paper available there in adobe format. Yes, someone really does listen to Public Radio.
