Understanding Helminthic Therapy | 1 CEU (general, accredited by AANP)
I have been in practice for decades with thousands of patients, but so what? You’re only as good as your misconceptions, and those you can bring to the grave with you.
A decade ago, after 20 years of practice, the universe in her wisdom saw fit to destroy one of my misconceptions. Parasites are bad. Are they? Doesn’t that sound like almost a century ago with regard to bacteria? Then we learned. Good bacteria are good, bad bacteria are bad.
I will agree that bad parasites are bad, but I will try and convince you that good parasites are good. I have used the good parasites with many people that were at the end of their autoimmune rope. It has given me a tool that actually works for what the old timers referred to as the chronic incurables. They can remove the ‘obstacles to the cure”. At its best I hope my talk will dispel a misconception or two and help you look at our friend “Wormy” with new eyes.
Stephen Michael Nenninger, NMD
Dr. Stephen Michael Nenninger is a 1995 graduate of naturopathic medical school with decades of experience in clinical practice. Over the years, they have successfully supported thousands of patients using individualized naturopathic modalities, including homeopathy, herbal medicine, dietary interventions, and allergy testing.
While many patients saw remarkable improvements, Dr. Nenninger noticed that a small but significant percentage—about 5%—did not respond as expected. This group included not only patients but also members of their own family, all of whom had been affected by autoimmune disease. Frustrated by the lack of lasting solutions for these complex cases, Dr. Nenninger began a deep and relentless search for answers.
After extensive research, a pivotal discovery emerged: the role of helminths—organisms such as hookworms—in immune system regulation. Historical and scientific evidence revealed that humans, along with all other mammals (and even dinosaurs), co-evolved with these organisms. The modern eradication of helminths may represent a significant shift in immune function, potentially contributing to the rise in autoimmune and inflammatory diseases.
This insight became deeply personal when Dr. Nenninger’s son was diagnosed with primary sclerosing cholangitis, a rare and life-threatening autoimmune condition. Conventional and natural therapies proved ineffective. However, after initiating carefully selected hookworm therapy, his laboratory markers normalized within three months—a powerful turning point in both his health and Dr. Nenninger’s clinical direction.
Dr. Nenninger is now regarded as a leading authority in helminthic therapy and may have the largest helminthic practice currently in existence. Their work continues to challenge conventional assumptions and offer new hope for patients with treatment-resistant autoimmune conditions. More on this innovative approach can be found in their book, available through their website.
