Swooping Evil venom

Swooping Evil venom is a type of substance with the ability to erase the memories of anyone it touches.

History
In 1926, Newt Scamander owned one Swooping Evil. When Credence Barebone wrecked havoc on the streets of New York as an Obsucuriel and revealed the secret Wizarding society to the No-Maj community, Seraphina Picquery thought it would be impossible to Obliviate every single one of them. However, Newt Scamander suggested that they use the venom of the Swooping Evil with the help of a Thunderbird, which can create storms as it flies, to erase the memories of every No-Maj in New York. Seraphina agreed, and the Thunderbird created a storm of rain which was actually Swooping Evil venom to successfully salvage the secrecy of the Wizarding society.
