Department for the Regulation and Control of Magical Creatures potion stores

The Department for the Regulation and Control of Magical Creatures had their own potion stores.

Gethsemane Prickle noted that the department's potion stores were "a bit light" when she suggested Draught of Living Death to catch a troll that had fled into Muggle London after drinking an Invisibility Potion — Mathilda Grimblehawk and her partner were tasked with collecting the necessary ingredients and to find a suitable way to trick the troll into drinking it.
