Barcarian claw salt was a trade good originating from the world of Barcaria, a planet. This substance was rumored to look like eyeballs, and possessed an extremely powerful smell, an odor that was amplified for Wookiees due to their heightened sense of smell.
On one occasion, Han Solo and Chewbacca were smuggling Barcarian claw salt when they were ambushed by the Natalon Core Bandits.
