Report Abuse. Yes, Histamine is a hormone. It's an amine secreted by the brain and stored in a number of cells (e.g., mast cells, basophils, enterochromaffin cells).Normally, there is a low level of histamine circulating in the body. However, the release of histamine can be triggered by an event such as a mosquito bite.
Histamine is the primary effector substance released by the mast cell in response to an allergen. Antihistamines block H1 (histamine, type 1) receptors found on blood vessel endothelial cells and smooth muscle cells. The smooth muscles are located in the breathing passages, internal organs, intestines, and blood vessels of the body.
