In this episode of Plants of the Gods, ethnobotanist Dr. Mark Plotkin takes us on a sweeping journey through the epic history of the spice trade—one of the most transformative chapters in global history. From ancient trade routes and religious rituals to colonial conquests and modern capitalism, spices like cinnamon, pepper, nutmeg, and cloves have shaped agriculture, medicine, navigation, and even warfare. Dr. Plotkin also reviews Roger Crowley’s gripping new book, Spice: The 16th-Century Contest That Shaped the Modern World.
