Elizabeth's take on this term...
The exposure to something outside the human body may trigger the inflammatory response, resulting in undesirable symptoms in the body.
An inflammatory trigger may be a food or drink, a chemical additive or preservative, a fragrance or added flavor chemical, a pharmaceutical, an air- or water-borne contaminant, a parasite, or anything else foreign to the natural integrity of the human body. Exposure to a trigger may cause symptoms of pain, discomfort, or dysfunction.
