Histamine liberators
Substances that release histamine from cells, worsening the symptoms of HIT.
Histamine liberators are substances that cause the body to release its own histamine from cellular stores (eg from mast cells). They may not contain histamine themselves, but their consumption or contact can lead to a sudden worsening of the symptoms of histamine intolerance. Common liberators include, for example, strawberries, tomatoes, citrus fruits, alcohol or some food additives.
