— The foul taste of this potion

Herbicide Potion (or simply Herbicide) was a poisonous potion that killed or damaged plants. It had a disgusting taste and was not fit for human consumption, since it may have negatively affected the drinker's health. The recipe for this potion could be found in Magical Drafts and Potions.

History

"Today we will create a potent Herbicide. Do not let one drop find its way to the Greenhouses. Watch closely."

— Professor Snape introducing first years to this potion in class

During the 1984–1985 school year at Hogwarts School of Witchcraft and Wizardry, Professor Severus Snape taught his first-year Potions students how to brew this potion.

Behind the scenes

• Probably due to its poor points per galleon-minute, according to the Pottermore Insider, Herbicide was the least commonly brewed potion.
• While the Antidote to Common Poisons had an even worse points per galleon-minute, it was much quicker to make. Additionally all of Herbicide ingredients came in bottles, which were known for being extremely unwieldy.
• Although Pottermore described this as an advanced potion, the brewing of it has been shown to be taught in first year Potions classes in the first video game and Harry Potter: Hogwarts Mystery.
• In LEGO Harry Potter: Years 1-4 and LEGO Harry Potter: Years 5-7, some LEGO plants can be destroyed by being made to ingest black bottles of poison, which are possibly bottles of the Herbicide Potion.
