What Is Histamine? Histamine is an important part of your bodyâs immune response, but high levels of the chemical compound can cause health problems. Histamine is a chemical produced in cells throughout the body as part of the bodyâs inflammatory response to allergy, infection, or injury. When damaged or exposed to allergens, cells in the skin, nose, throat and lungs release histamine, resulting in pain, itchiness, redness, runny nose, and wheezing.
