Skin conditions have been notoriously hard to treat until recent research has identified histamine as being a major contributing factor to the development of hives, eczema and acne.

Histamine is a compound in the body which is released in response to injury, inflammation, allergic reactions and autoimmunity.  When histamine is released it exerts its affect on the skin causing itchiness, redness, rash, flushing, hives, eczema and acne.

Histamine can build up in the body due to:


    • DAO gene mutation – the DAO enzyme breaks histamine down in the gut


    • HNMT gene mutation – the HNMT enzyme breaks down intracellular histamine (MTHR gene mutation and methylation cycle issues can impact the functioning of this enzyme)


    • Overgrowth of histamine releasing bacteria in the gut


    • Many foods contain histamine including fermented foods (soy, miso, kimchi, sauerkraut), aged cheeses, alcohol, yeast, shellfish, canned fish, processed meats, chocolate and tomatoes.


  • Oestrogen also increases histamines and at the same time decreases DAO enzyme activity. To make matters worse, histamine then stimulates the ovaries to produce more oestrogen leading to a vicious cycle of high histamines and high oestrogens.



Treatment is different for each person depending on the drivers of the histamine release.  Thorough case taking is essential to understand all the possible factors contributing to the over production of histamine OR the inability to clear histamine from the body.
