Histamine is a chemical released by mast cells when our body senses danger, like an allergen, virus, or bacteria. Histamine is also involved in digestion and delivering messages between the body and the brain. 2. Symptoms Related to Histamine. Typical symptoms are migraines, skin issues like swelling, eczema or flushing, hives, vertigo, itchy eyes, insomnia, runny nose, congestion, or a racing heart when drinking alcohol. Other symptoms include dermatographia anxiety, panic attacks, and the feeling of being allergic to the sun. 3. What Is Mast Cell Activation Syndrome? Mast cells are supposed to release inflammatory chemicals when there is a threat. However, with mass activation syndrome, you're much more sensitive, and the mast cells release chemicals when there are no threats. Dr. Becky Campbell is a board-certified doctor of natural medicine.
