Histamine Intolerance
Histamine Intolerance is an intolerance of ingested histamine probably caused by dysfunction of the two metabolizing enzymes HNMT and DAO. The symptoms are similar to allegic reactions.

In patients with histamine intolerance diarrhea manifests after the ingestion of greater amounts of biogenic amines. |
