On page 340 of the English edition
Harry was reading and rereading a passage about the uses of scurvy-grass, lavage ans sneezewort and not taking in a word of it
These plants are moste efficacious in the inflaming of the braine, and are therefore much used in Confusing and Befuddlement Drafhts, where the wizard is desirious of producing hot-headedness and recklessness
That is how it is written in the book, in italics, to bring attention to it. this would raise the question, is someone close to Harry (would have to be close to administer the draft) in league with Voldermont to make Harry act recklessly?
Any views appreciated
