Start Here
New to mold and biotoxin illness? Begin here with the foundational concepts: what mold illness is, how exposure affects the body, and how to approach recovery step by step.
Mold Illness & Mycotoxins
How toxic mold, mycotoxins and other biotoxins affect human health, the symptoms they can cause, and how exposure is evaluated.
Mast Cells & Histamine
The role of mast cell activation and histamine intolerance in mold-related illness, and why reactions can feel so widespread.
Detoxification
How the body processes and eliminates mycotoxins, including binders, liver and bile flow, glutathione, and nutritional support.
Gut & Microbiome
The connection between mold exposure, gut barrier function, dysbiosis, yeast overgrowth, and food sensitivities.
Immune Dysfunction & Autoimmunity
How biotoxin exposure can disrupt immune balance, drive chronic inflammation, and contribute to autoimmune patterns.
Recovery, Lifestyle & Environment
Practical guidance on diet, nervous system support, sleep, and creating a healthier home environment to support lasting recovery.
For Practitioners
Clinical education for practitioners: assessment, lab interpretation, case patterns, and treatment frameworks for complex mold and biotoxin cases.
