Once you have the right ingredients you can begin to brew Polyjuice Potion. Some of the ingredients you require may be hard to find so you will need to be resourceful and eagle-eyed. The instructions have been split into two stages and you will have to complete stage one of the brewing process before you can move on to the second stage, even if you have all of the ingredients.

Take care and persevere, this is a complicated and challenging potion that even adult witches and wizards struggle to brew correctly.


Polyjuice Potion has the power to transform the drinker into somebody else.

New from J.K. Rowling

The Polyjuice Potion, which is a complex and time-consuming concoction, is best left to highly skilled witches and wizards. It enables the consumer to assume the physical appearance of another person, as long as they have first procured part of that individual's body to add to the brew (this may be anything - toenail clippings, dandruff or worse - but it is most usual to use hair). The idea that a witch or wizard might make evil use of parts of the body is an ancient one, and exists in the folklore and superstitions of many cultures.

The effect of the potion is only temporary, and depending on how well it has been brewed, may last anything from between ten minutes and twelve hours. You can change age, sex and race by taking the Polyjuice Potion, but not species.

The fact that Hermione is able to make a competent Polyjuice Potion at the age of twelve is testimony to her outstanding magical ability, because it is a potion that many adult witches and wizards fear to attempt.

J.K. Rowling's thoughts

I remember creating the full list of ingredients for the Polyjuice Potion. Each one was carefully selected. Lacewing flies (the first part of the name suggested an intertwining or binding together of two identities); leeches (to suck the essence out of one and into the other); horn of a Bicorn (the idea of duality); knotgrass (another hint of being tied to another person); fluxweed (the mutability of the body as it changed into another) and Boomslang skin (a shedded outer body and a new inner).

From the Story

Harry Potter and the Chamber of Secrets

Discovered in chapter 10, The Rogue Bludger

Polyjuice Potion has the power to transform the drinker into somebody else. The recipe can be found in Moste Potente Potions, which is housed in the Restricted Section of the Hogwarts library. It is a very complicated potion and requires ingredients such as lacewing flies, leeches, fluxweed, knotgrass, powdered horn of a Bicorn and shredded skin of a Boomslang as well as a bit of whoever the drinker intends to turn into. Harry, Ron and Hermione want to take the potion so that they can turn into Slytherins and find out if Draco Malfoy is the heir of Slytherin, as they suspect.

Harry Potter and the Half-Blood Prince

Discovered in chapter 9, The Half-Blood Prince

Professor Slughorn prepares a cauldron of Polyjuice Potion to show his sixth-year Potions students.

Harry Potter and the Deathly Hallows

Discovered in chapter 4, The Seven Potters

Ron, Hermione, Fred, George, Mundungus and Fleur take Polyjuice Potion to transform into identical Harry Potters for the journey from Privet Drive.

Brew times

Polyjuice Potion - Part 1:

Polyjuice Potion - Part 2:

Time to return to cauldron

Polyjuice Potion - Part 1:

(note: these times seam to have changed as im being given 3 minutes for copper. lost 3 Potions in a row befor figuring out why then tested by waiting for it to turn over and it said 3 minutes.) Polyjuice Potion - Part 2:


  • Polyjuice Potion Parts 1 and 2 are two separate potions, therefore Part 1 isn't lost even if you mess up Part 2
  • Part 1 doesn't disappear from brewed potion index after completing Part 2, so you can have one Part 1 and multiple Parts 2
  • Lacewings bottle is very difficult to navigate, so it's a common practice to knock it over the table and catch individual scoops as they fall out of the bottle
  • You have roughly 7-9 hours to check on the Part 2 after it's brewed before it spoiled.
