Histamine is a substance produced in the body that acts as a neurotransmitter. It is an important part of the reticular activating system (the part of the brain that wakes people up). Histamine may serve as a biomarker for problems or dysfunction in the hypothalamus. It is also involved in a number of other bodily processes, including the immune and inflammatory responses and the regulation of gut function.
