Flavokavain B is a flavokavain found in the kava plant.[1] In 2010 a paper was published identifying it as a hepatotoxin.[2] Another paper published in 2013 suggests that Flavokavain B might be effective in killing bone cancer cells by pointing out evidence of apoptosis and cell cycle arrest by Flacokavain B treatment with less toxicity than the standard treatments.[3] Flavokavain B has been demonstrated to possess potent apoptotic abilities.[4]
