What Does “Histamine” Mean

Histamine is a natural chemical made by the body. It helps with things like immune responses, stomach acid, and signals in the brain.

People usually hear the word histamine when talking about allergies. When your body reacts to pollen, dust, or certain foods, it can release histamine and cause symptoms like sneezing, itching, or a runny nose.
