The Amenicas Weed was a weed grown on a planet in the Unknown Regions, purportedly near the original Killik Nest. When used by a Force-sensitive individual, the weed caused amnesia in any being that was susceptible to the pheromones that the weed emitted. Abigaile Kenobi fell victim to one of these due to the efforts of Bogan Mandrex, which led to the birth of Nathaniel Kenobi Solo.
