My fellow collegues Let us use caution with our terminology. A case of anaphylactic shock, or even a simple case or urticaria (hives) attributed to a perfumed substance IN THE AIR has not been documented in the literature. The term "allergy" is casually used in our descriptive world. Now, do not confuse this assertion with perfumes in general. Contact dermatitis could definitely produce a severe reaction in a sensitized individual if they placed the substance on their skin. People get easily confused between a sensitive nose and an allergic sensitivity. Pollen in the air is also a CONTACT allergy with a substance in the air. Least we confuse our terminology. True allergies are actual histamine reactions involving mast cells.
