Understanding & Healing Histamine Intolerance & Mast Cell Activation Syndrome (MCAS) with Diet & Medicinal Herbs

This week (3/27/25) I hosted a class on histamine intolerance & mast cells activation syndrome at the Vermont Center for Integrative Herbalism. I gave an overview of the latest research on the pathophysiology of these disorders, how to differentiate them from one another, and how to address their symptoms and root causes with dietary changes, herbal medicine, and supplementation. You can purchase the recording of this class at this link here. But I also wanted to post a transcript of this information here on my website, so that I can cite my sources more closely and spread this information to a wider audience. A couple people in the class had mentioned that my presentation was the most detailed and comprehensive they'd ever seen, which I was surprised by since histamine intolerance is such a hot topic and so many alternative practitioners want to share their opinions about it online (often without grounding their claims in scientific research). As my regular readers know, this website is all about empowering people to take charge of their own health by deepening their knowledge of health and disease. So in that vein, here is a write up of the discussion we had in class. It will be long but I still had to cut out things for time! So please tell me what sub-topics you'd like to hear more about related to histamine intolerance & MCAS.
