In the 1985–1986 school year at Hogwarts School of Witchcraft and Wizardry, Professor Severus Snape taught Jacob's sibling and Chiara Lobosca how to brew this potion, which they later did, in order to help Pippa Macmillan recall details about an event where she was attacked by a white creature.
This potion was brewed and used heavily by volunteer wizards and witches of the Statute of Secrecy Task Force in the 2010s to help address the growing threat of the Calamity in the Wizarding world.
