We’re sharing a bonus episode from our friends at Revisionist History, Malcolm Gladwell’s podcast about things misunderstood and overlooked. This season, Malcolm’s obsessed with experiments – natural experiments, scientific experiments, thought experiments. In this preview, you’ll hear about a mysterious and disfiguring disease that plagued parts of the world in the last century. No one could find a remedy, until a doctor in Ohio conducted a controversial experiment and finally found a cure…with an everyday condiment.
