Biotoxin University
Education for biotoxin, environmental, inflammatory, and neuroimmune illness.
Biotoxin University brings structure, clarity, and source-based education to complex conditions involving environmental exposure, microbial triggers, chronic inflammation, CIRS, PANS/PANDAS, Lyme, autism-related neuroimmune impacts, apraxia, and medically sensitive environments.
New to CIRS? Start Here.
CIRS can feel like many different illnesses happening at the same time. Brain fog, fatigue, poor sleep, pain, sensitivity, and reactions to certain buildings may seem unrelated until someone explains the larger pattern.
This free five-part mini course uses a simple city metaphor to explain what may be happening inside the body, why the body can become stuck in emergency mode, how the environment can become part of the story, and why so many patients struggle to find one clear explanation.
No medical background is required.
