"Snape made them all nervous, breathing down their necks while they tried to remember how to make a Forgetfulness potion."
— The first year Potions exam in 1992 involving this potion[src]

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.[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]
