Histamine is one of the best known mediators - it is responsible for causing many of the symptoms associated with allergies. Histamine opens small blood vessels causing them to leak fluid. This results in inflammation: warming and swelling of the skin, itching and watery eyes. Histamine causes sneezing and increased mucus production in the nasal cavity and airways that leads to runny nose, post-nasal drip and cough.
