'

Histamine is an organic nitrogen compound found in the body and is involved in immune responses as well as in the modulation of physiological functions such as gastric acid secretion and vasodilation. It is an important mediator of inflammation and plays a role in allergic reactions, causing the characteristic symptoms of sneezing, itching, and swelling that are so common in allergic reactions. Histamine is derived from the amino acid histidine and is found in many foods and medications.

Histamine can be used as a medication, either alone or in combination with other drugs, to help reduce the signs and symptoms of an allergic reaction. It is also used in the treatment of some forms of anaphylactic shock, a severe allergic reaction that can be life-threatening. Histamine can also be used in the diagnosis of food allergies, as well as in certain tests to determine the cause of an allergic reaction.

In addition, histamine is used in the diagnosis and treatment of some other medical conditions. It can be used to treat certain types of nausea and vomiting, as well as to help with the symptoms of certain stomach and intestinal disorders. Histamine can also be used to diagnose and treat certain types of asthma, as well as to treat and manage some types of hives and rashes. In some cases, histamine may be used as a treatment for certain types of hypertension.
