A Truth Serum,[2] also known as a Truth Potion,[1][3] was a potion that could be used to gain the truth from anyone.[1][4] Jobberknoll feathers were a known ingredient of Truth Serums.[2]

Veritaserum was the most powerful Truth Serum there was. It was a colourless, water-like fluid. Three drops was enough to force the drinker to reveal their deepest secrets.[1][4][3] As such, the Ministry of Magic restricted its usage.[5] It could be countered with an antidote[6][7] or Occlumency.[8]
