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?
A histamine chamber is used to test for histamine sensitivity or allergies by exposing the individual to controlled levels of histamine and observing their reaction. This type of test can help diagnose conditions like histamine intolerance or allergies.
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.
