Behind the scenes

  • Brewing a Herbicide potion is free, as all of its ingredients regenerate.
  • Probably due to its poor points per galleon-minute, according to the Pottermore Insider, Herbicide is the least commonly brewed potion.
  • While the Antidote to Common Poisons has an even worse points per galleon-minute, it is much quicker to make. Additionally all of Herbicide ingredients come in bottles, which are known for being extremely unwieldy.
