Histamine is produced by the body in response to allergens, and antihistamine drugs work by blocking the action of histamine in the body.
Histamine is a neurotransmitter produced by basophils (a type of white blood cell).
When histamine is produced in the body, it can be over-produced because we are taking too much of one thing or another that our body cannot use.

Histamine is primarily secreted by basophils and mast cells in response to allergens or injury. It is also produced by enterochromaffin-like cells in the stomach.

Mast cells and basophils release histamine. When histamine is released, it causes blood vessels to dilate, which can lead to symptoms such as redness and swelling (inflammation), increased mucus production, and smooth muscle contraction, resulting in symptoms like itching and bronchoconstriction.
Mast cells are the primary cells that produce and release histamine. Histamine is stored in granules within mast cells and is released in response to allergens and other triggers, leading to symptoms of allergy such as itching, sneezing, and swelling.
Histamine H2 receptor blockers work by reducing the production of stomach acid by blocking the action of histamine on the H2 receptors in the stomach lining. This helps to decrease the amount of acid produced, which can be useful in treating conditions like acid reflux, ulcers, and gastritis.
Histamine and heparin
Histamine is produced naturally by most animals, some plants and organisms. It's also present in some insects' venom. I believe it is a protein, formed by the decarboxylation of the amino acid histidide.
Histamine is the chemical produced by white blood cells that increase blood flow to an injured area. It causes blood vessels to dilate, which allows more blood to flow to the affected area to deliver immune cells and nutrients for healing.
