Histamine has many functions: as a neurotransmitter, communicating messages to and from the brain and nervous system; triggering the release of stomach acid to help digestion; and it can also be released after stress, injury or allergic reaction as part of the body’s immune response.
 
Histamine intolerance is the body’s reaction to an imbalance between accumulated histamine and the capacity to break it down. When the body is unable to break histamine down quickly enough it becomes toxic. Symptoms of histamine toxicity may include skin irritation or breathing difficulties (mimicking an allergic reaction), digestive problems, headaches, insomnia and anxiety.
 
Histamine production is closely tied to oestrogen – so this can sometimes be an invaluable report when battling symptoms of oestrogen dominance.
