A histamine reaction typically causes symptoms such as itching, hives, swelling, and redness, often associated with allergic responses. Other symptoms may include nasal congestion, sneezing, headaches, and gastrointestinal disturbances. In more severe cases, it can lead to anaphylaxis, which is a life-threatening reaction characterized by difficulty breathing, rapid heartbeat, and a drop in blood pressure. The severity of symptoms varies depending on the individual and the amount of histamine released in the body.

What is the application of histamine chamber?

Release of the chemical histamine causes?
Release of histamine causes dilation of blood vessels, increased vascular permeability, and smooth muscle contraction. This can result in symptoms such as itching, redness, swelling, and bronchoconstriction depending on the location of release and the receptors it activates.
What is the hestamine?
histamine is a compound produced in the body which causes pain and sweeling
What causes capillaries to dilate during inflammatory response?
