A Truth Serum is a potion that can be used to gain the truth from anyone. Jobberknoll feathers are a known ingredient of Truth Serums.
Veritaserum is the most powerful Truth Serum there is. It is a colorless, water-like fluid. Three drops is enough to force the drinker to reveal the deepest secrets. As such, the Ministry of Magic has restricted its usage. It can be countered with an antidote or Occlumency.
