Dr. Becky Campbell's website describes a virtual functional medicine practice focused on histamine intolerance, MCAS, and mold/mycotoxin illness. Her own histamine intolerance journey — childhood heat intolerance, hives, scalp tingling and fatigue from high-histamine foods, plus later migraines, vertigo, heart palpitations, anxiety, panic attacks, and acid reflux — informs her approach. The practice offers virtual patient consultations with Dr. Campbell's team for one-on-one root-cause work, plus an online Histamine Course and a Practitioner Community for clinicians. Free patient resources include the Methylation Reset Guide, 10 Signs You Might Be Reacting to Mold, Commonly Overlooked Labs guide, Drainage First Guide, Guide for Histamine Intolerance, MCAS Made Simple, Mold Recovery Toolbox, Red Light Therapy Guide, Understanding Your DUTCH Lab, Daily Food Journal, and a Yes/No/Maybe Food List. Note: per the site disclaimer, naturopathic doctors are not licensed in Florida; the practice operates as a Doctor of Natural Medicine.
