YMMV / House of the Dragon S1 E2: "The Rogue Prince"

• Aluminum Christmas Trees: Grand Maester Mellos uses maggots to remove the dead flesh on Viserys's badly infected pinky finger. Not only is this an actual ancient method, but it's so effective that it's seen a resurgence in modern medicine, nowadays known as "maggot therapy". Grotesque as it may seem, it's a very effective way to remove dead and infected tissue, while leaving the living flesh intact.
