Asthma treatment wasn’t always built around inhalers. It once came from poisonous plants, smoke, and a mysterious dream. In this episode, we explore the strange history of anticholinergics, tracing the path from Jimsonweed and belladonna to atropine, acetylcholine, and Otto Loewi’s discovery of “Vagusstoff.” We follow how Loewi’s frog-heart experiment helped prove that nerves communicate through chemical messengers, and how Henry Dale’s work connected those discoveries to the vagus nerve and airway constriction. We examine why early plant-based asthma remedies could open the airways while also causing dangerous side effects, and how that understanding eventually led to modern anticholinergic therapy. This episode reveals how a dream, a frog heart, and a toxic smoke helped shape the pharmacology of asthma.
