The Forgetfulness Potion was a potion which caused an unknown degree of memory loss in the drinker.[1] The recipe for this potion could be found in Magical Drafts and Potions; its key ingredients included 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 asking Penny Haywood a question[src]
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 to erase a painful memory.[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]
Second-year students studied this potion in the 2009–2010 school year.[4]
