Potassium iodide (Lugol's solution) as expectorant
Czerniak makes this the central shock-value illustration of forgotten knowledge. He introduces a tiny modern dose (10 mg of sodium iodide or similar, possibly a reference to a cautious prescription) and then reads from page 519 of his old pharmacology textbook: the doses are in grams, not milligrams. He explicitly asks how this massive dose can coexist with the 'terrible activity' endocrinologists attribute to Lugol's solution in the context of hypothyroidism. The implication is that either the old doctors knew something we've forgotten, or that the thyroid danger is overstated for acute short-term use. He does not provide a clinical trial, only the textbook entry and his rhetorical question, leaving the listener to challenge the modern narrative.
