Senflax, a powerful neurotoxin, originated from a plant exclusive to the Cadannia jungles. This pale yellow fluid served mainly as a sedative, enabling a person to remain aware while simultaneously nullifying all physical feelings. Although it caused paralysis in the body's main muscles, it did not affect essential organs, regardless of the amount given. Furthermore, Senflax interfered with a person's mental abilities, hindering the focus needed to control the Force. The Ambrian healer Caleb maintained a stock of Senflax alongside his numerous other natural herbs and treatments in his shack's cellar. Ten years following Caleb's death, his daughter Serra retrieved it and provided it to the Iktotchi assassin Huntress in their endeavor to apprehend Serra's adversary, Darth Bane. A prepared Sith could incinerate the poison with the fire of Bogan, but even Bane, unaware, was overcome and taken prisoner.
