The most powerful love potion in existence. Smelling different to each person according to what they find attractive, the potion was considered to be dangerous as it could induce obsessive infatuation in the unsuspecting drinker. The potion is presented by Professor Slughorn to Harry and the sixth-years as an introduction to N.E.W.T. level concoctions. Hermione recognises the potion, proving herself to the new Potions master while also revealing that, to her, the potion smells of freshly-mown grass and new parchment.
