Hermione Granger: "What are the three most crucial ingredients in a Forgetfulness Potion?"
Ronald Weasley: "I forgot."
— Ron and Hermione studying for their final exams[src]

The Forgetfulness Potion is a potion which causes an unknown degree of memory loss in the drinker.[1] The recipe for this potion can be found in Magical Drafts and Potions; its key ingredients include Lethe River Water, mistletoe berries, and Valerian sprigs.[1][3]

History

"I feel like I've drunk a Forgetfulness Potion. How do I do this again?"
Jacob's sibling asks Penny Haywood a question

During the 1986–1987 school year, Penny Haywood asked Jacob's sibling to brew the potion with her in secret, intending to drink it herself.[3]

Since this potion was of beginner's level, Professor Severus Snape had his first year students brew this potion for their final exam in 1992.[2]

Recipe

Part 1

  1. Add 2 drops of Lethe River Water to your cauldron
  2. Gently heat for 20 seconds
  3. Add 2 Valerian sprigs to your cauldron
  4. Stir 3 times, clockwise
  5. Wave your wand
  6. Leave to brew and return in 45-60 minutes

Part 2

  1. Add 2 measures of Standard Ingredient to the mortar
  2. Add 4 mistletoe berries to the mortar
  3. Crush into a medium-fine powder using the pestle
  4. Add 2 pinches of the crushed mixture to your cauldron
  5. Stir 5 times, anti-clockwise
  6. Wave your wand to complete the potion

Behind the scenes

  • Given that every potion's brewing process must include a magical component to complete it, the most likely spell to complete this potion's brewing process is a Memory Charm.
