The symptoms of histamine intolerance will normally be felt between a few minutes to a couple of hours after the intake of food high in histamine or foods that cause the release of histamine. However, it is not always so that the same symptoms appear.
Several organs can be affected by histamine intolerance:
the skin
the gastro-intestinal tract

The following symptoms can appear:
