The book's master argument against symptom-by-symptom medicine. The "Heads of the Hydra" list — migraines, anxiety, COPD, digestive trouble, insomnia, fibromyalgia — isn't dozens of diseases but one stuck autonomic state wearing different masks; the comorbidity is the clue, not a coincidence. "Rather than treating individual symptoms as separate issues with a pill to be taken for each one, it would be preferable to find a common thread that links them." Cut off heads one at a time and two grow back; reinstate ventral vagal function and the beast dies at the root. Stated as his clinical position from his own practice — he labels his cases anecdotal, not trial results.
