About the Workshop

Please join us for a truly in-depth and practical review of Mold toxicity and its complications. 

This workshop is designed for medical practitioners who have MD, DO, ND, NP or PA certification. In this workshop, we will be discussing the presentation of mold toxicity, how to test patients and then step-by-step treatment programs for patients who have a robust constitution and for those who have become more sensitive. We will delve into the finer points of the entire detoxification process, and then dig into the conditions frequently triggered by mold toxicity that often present stumbling blocks in treatment: mast cell activation, limbic dysfunction and vagal nerve dysfunction.

We will include a discussion of common comorbidities with mold toxicity including Lyme disease, Heavy Metal toxicity, and Endocrine Disruption (among others).

Episode Description

Millions of people have sought medical care, and found that they have hit a wall with their doctor even though they feel very sick. There is an epidemic of tick born illnesses (Lyme Disease), mold exposure, chemicals and other toxins that are causing illness. Unfortunately, these illnesses are falling through the cracks in our health care system. Dr. Neil Nathan is discussing his book “Toxic”, which is a easy to read, but thorough journey through these toxic illnesses.

More about Toxic…Heal Your Body

Now available as an audiobook on Amazon.com


Millions of people are suffering from chronic illnesses that, unbeknownst to them, are caused by exposure to mold, Lyme disease, other infectious agents, and other environmental toxins. Millions. Because the symptoms of these illnesses are so varied and unusual, many of these individuals have sought medical care only to be dismissed, as if what they are experiencing is “in their head.” Many (if not most) have tried to tough it out and continue to function without hope of improvement. Unfortunately, their illnesses are very real. Toxic is a book of hope for these individuals, their loved ones, and the physicians who provide their care. Over many years of helping thousands of patients recover their health (even after their previous doctors had given up on them), Dr. Neil Nathan has come to understand some of the most common causes for these debilitating illnesses, which allows for the utilization of more precise and effective forms of treatment.
The goal of this book is to shed light on these complex illnesses so that suffering patients and their families can get the help they so desperately need. In the book, you will find:

  • Information about how extreme sensitivity and toxicity develop in the body, how they differ, and how they often overlap
  • Detailed descriptions of each of the four major causes of hypersensitivity and toxicity: mold, Bartonella (a co-infection of Lyme disease), mast cell activation, and porphyria and carbon monoxide poisoning
  • An outline of the cell danger response, a revolutionary model developed by Dr. Robert Naviaux that explains how the body essentially gets “stuck” fighting a threat even after the danger has passed
  • A system-by-system plan for “rebooting” the body to break the cycle of illness and allow healing to begin
  • Information about coping with stress and embracing an emotional and/or spiritual awakening on a path to wellness

Dr. Nathan’s wisdom, clinical acumen, kindness, compassion, careful listening to his patients, and lifetime of experience have sparked medical insights that have the power to inspire a new generation of physicians.”

                      —Robert Naviaux, MD, PhD

                          from the foreword

Dr. Neil Nathan’s book, Toxic—Heal Your Body, fills a critical niche in the evaluation and treatment of patients with mold illness, tick-borne illnesses, and chemical sensitivities.  This is one of the most difficult, and widely misunderstood, areas of medicine, yet critical to so many patients in need. Dr. Nathan brings a clinical experience and expertise that is unmatched when it comes to multiple chemical sensitivities.  If you are a patient with these problems or a practitioner caring for such patients, this is the most important book you will read this year.

Mold and Mycotoxins

“Mold & Mycotoxins: Current Evaluation and Treatment 2016”

This book is intended to help both medical practitioners and patients to understand our growing understanding of how mold toxicity and mycotoxins can profoundly affect health. It provides an overview of how mycotoxins create an unrelenting inflammatory process that influences the immune system, nervous system, endocrine system, gastrointestinal system, emotions and pain. It reviews the current approaches to diagnosis and treatment.


On Hope and Healing: For Those Who Have Fallen Through the Medical Cracks is a resource book offering the latest information on a range of illnesses that most family practitioners are unequipped to diagnose or treat effectively. Written in nontechnical language, On Hope and Healing also offers clear, readable explanations for the causes and cures of today’s onslaught of complex/chronic illnesses. Physicians and patients alike will benefit from this book.

With unusual clarity and first-rate science, Dr. Neil Nathan encourages us to shift our thinking to a more holistic, multifactorial, and positive approach to chronic and recurrent illness. On Hope and Healing eloquently transports health and medicine into the 21st century. It is, I believe, by far the best book, the most comprehensive book, and the clearest book ever written about integrative holistic medicine.
