The xharnoh plant was a plant that was found on Naboo. It grew on the sides of Naboo's various rivers and lakes. Their roots were used to make neural enhancers. In 1 ABY Lieutenant Karenna Dunnels of the Royal Naboo Security Forces hired a spacer to collect a number of roots to make neural boosters for the security force, prior to the raid on the Mummer bunker.
Xharnoh plants appeared in the 2003 video game Star Wars Galaxies, a massively multiplayer online roleplaying game developed by Sony Online Entertainment and published by LucasArts, prior to its closure on December 15, 2011. Xharnoh plants were added to the game as part of the "Legacy Quest" with the release of the "Publish 25," a.k.a. the "New Game Enhancements," on November 15, 2005. Xharnoh plants used the same model than the raventhorn plants found on Yavin 4.
