Histamine is a natural chemical your body makes. It helps with things like allergies, stomach acid, and the way your immune system reacts to danger.
People usually hear about histamine when talking about allergies or foods. For example, when your body reacts to pollen, dust, or certain foods, histamine is one of the chemicals involved in that reaction.
