On this very special crossover episode with our friend Matt Candeias from In Defense of Plants, we’re switching things up from poison to remedy, focusing on the plant-derived wonder drug, aspirin! We cover the ancient use of salicylic acid-containing willow bark to relieve pain and fevers and then reveal how such a harsh compound was transformed into a useable pharmaceutical. We also delve into what happens in your body when you pop an aspirin and discuss why on earth so many plants make this incredible compound. Spoiler – it’s not just a wonder drug for humans.
