The histamine that accumulates in the intestine and has not been broken down is excreted in the stool.

What exactly happens with a histamine intolerance?
Histamine plays important roles in the body, with excessive levels of histamine leading to pseudo-allergic intolerance reactions in the nervous system, gastrointestinal, and respiratory tracts . It acts as an inflammatory mediator against harmful substances. Anyone who has come into contact with a stinging nettle knows the sensation: red, itchy, painful, and swollen.
