This book is intended to be a concise overview of mold toxicity: how it presents (its symptoms), how to diagnose it and how to treat it. It also includes an overview of some common medical conditions that are triggered by mold toxicity, including limbic dysfunction, vagal nerve dysfunction and mast cell activation. Special attention is given to those patients who have become extremely sensitive to foods, medications and supplements from their exposure to mold to understand how those patients can be helped to overcome those sensitivities and heal.
