<P> When a person drinks the Draught of Living Death, they go into a deep sleep so strong that they appear to be dead, hence the name . It is made from powdered root of asphodel which is added to an infusion of wormwood, and was first mentioned in Harry's first potions lesson with Snape in Harry Potter and the Philosophers Stone . It was later mentioned in his first Potions lesson with Horace Slughorn in Half - Blood Prince when Harry receives top marks in Horace Slughorn's first NEWT (Nastily Exhausting Wizarding Tests) Potions class for brewing this potion so well, having used the handwritten advice in the Half - Blood Prince's book . He is then awarded a small bottle of the potion Felix Felicis as a prize . This potion is described as changing in colour during the process of being made . It has a texture and consistency akin to that of clear water . A process of examining the potency of the potion is to drop a new or fresh leaf in it--the leaf is instantaneously reduced to ashes . </P> <P> The Draught of Peace provides personal comfort, calms anxiety and soothes agitation . In Harry Potter and the Order of the Phoenix, Snape sets the potion as one of his lessons . It is a very difficult potion to make as the ingredients have to be added in a very specific order, the mixture has to be stirred exactly the right number of times and the heat of the flames on which it is simmering has to be lowered to exactly the right level for the right number of minutes before the final ingredient is added . Hannah Abbott had to have this potion in Order of the Phoenix to reduce her anxiety over the upcoming Ordinary Wizarding Levels (O.W.L.s). </P> <P> Felix Felicis, more commonly known as Liquid Luck, grants whoever drinks it unusually good luck . The time span of this luck depends on the amount imbibed . Liquid Luck is one of the hardest potions to make, as noted by Horace Slughorn; "It has to be cooked for 6 months on an extremely complicated formula, and if you make a tiniest mistake, the consequences are severe". Because of its properties, it is banned in all sporting events, competitions and examinations . In Rowling's original narrative, the potion looks akin to liquid gold . However, in the movie adaptation it is clear and water - like . Slughorn also noted that excessive consumption results in side effects that include giddiness and overzealousness, among other effects that are related to overconfidence . In Half - Blood Prince, Harry pretends to give some to Ron so that he will do well at Quidditch . Ron's luck turns for the better, with the confidence working as a placebo . Harry does use most of it later in the same novel in order to extract the true memory about Tom Riddle and Horcruxes from Slughorn (though it also has the pleasant side effect of causing Dean Thomas and Ginny Weasley to end their relationship), and the rest is shared between Ron, Hermione, Neville Longbottom and Ginny the night Death Eaters break into Hogwarts . </P> <P> Hiccoughing Potion (Hiccuping Potion in the American edition) is a simple potion and one of the first that Snape instructs his first - years to brew in The Philosopher's Stone . The potion, referred to by name, stops excessive hiccoughing in a matter of seconds . </P>
