Spice melange, often simply referred to as "the spice," is a fictional substance from Frank Herbert's science fiction series, Dune. It is a highly valuable and sought-after resource found only on the desert planet of Arrakis. The spice grants users heightened awareness, extended lifespan, and even prescient abilities, making it crucial for space navigation and interstellar travel. The production of spice melange is labor-intensive and dangerous, as it is harvested from the sands of Arrakis, where giant sandworms pose a significant threat. Control over spice production is a central theme in the Dune series, influencing politics, economy, and power dynamics across the universe.
