What if the missing piece in modern health isn’t another drug or supplement, but a return to an ancient partnership we’ve all but erased?
 
For most of human history, our bodies lived in constant companionship with helminths - tiny worms that shaped our immune systems and kept inflammation in check. In the modern sanitised world, these old allies have vanished, leaving behind skyrocketing rates of allergies, autoimmunity, and chronic disease.
 
This groundbreaking book explores the fascinating science and human stories behind helminthic therapy - the deliberate reintroduction of these misunderstood organisms to restore balance to our immune systems. Blending research with compelling case histories, it challenges our deepest assumptions about what it takes to be truly healthy.
 
Accessible, eye-opening, and often surprising, this book makes the case that our health depends on learning to live in harmony with the invisible world within us and is within reach of all of us.
