Dr. Becky Campbell runs 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, plus later migraines, vertigo, heart palpitations, anxiety, panic attacks, and acid reflux — informs her approach. The practice offers virtual one-on-one consultations plus an online Histamine Course and a Practitioner Community. Free patient resources include the Methylation Reset Guide, MCAS Made Simple, Mold Recovery Toolbox, and DUTCH Lab interpretation guide. Note: per site disclaimer, she practices as a Doctor of Natural Medicine in Florida (not licensed ND).
