Poisoned by Paleontology

Today's episode is about a toxin so powerful that a little smeared on the tip of a blowgun arrow is enough to silence every muscle in your body, including your diaphragm, stopping your breathing. How did a poison like this become a commonly used drug in modern medicine? We'll also go inside a Siberian prison cell where one of the most high-profile political prisoners on the planet collapses and dies. Was this a state-sponsored assassination using a poison from the rainforest? Listen to find out. Send us Fan Mail
