Hate Potion
From Jenny Everywhere Wiki
The “apples of discord” used by the Drove of the Demesmaekerite-Dyed Discordias were infused with a Hate Potion comparable to the Crew of the Copper-Colored Cupids' Love Potion, which made its targets more hateful. The two Potions could cancel each other out in either direction. (PROSE: The Drove of the Demesmaekerite-Dyed Discordias)
