I have invented a potion for the sixth year Potions class in a fic I'm writing, but I don't know what to call it.

It's a potion used on trauma patients, which dampens the effect of painful memories so that the subconscious can deal with them without causing the patient stress. The ingredients include moonstone, St. John's Wort (anti-depressant), Jobberknoll feathers and Belladonna. Any ideas on what such a potion could be called?

Thanks in advance,
