Tricky potion which is O.W.L. standard, taught in fifth-year Potions (OP12).
Rowling intentionally creates humor by contrasting the intended effect of this potion - peace - with the ingredient hellebore, which sounds rather evil (and is very poisonous as a matter of fact) and with the troubles the students have making it:
"Potter, what is this supposed to be?"
"The Draught of Peace," said Harry tensely.
See ELIXIR TO INDUCE EUPHORIA.
Cures the common cold.
Glover Hipworth invented the Pepperup Potion (fw).
Madam Pomfrey dispensed quite a lot of this when winter arrived. It leaves steam coming out of the drinker's ears for several hours (CS8).
If normal Muggle photographs are developed in certain potions, the resulting images will move.
Colin Creevey discovered this during his first year at Hogwarts. He was pretty excited about it (CS6).
The ingredients for many potions come from plants with magical qualities.

Effect: Transforms a person to look exactly like someone else. One dose lasts for one hour, but doses can be renewed, apparently indefinitely.
The instructions for making this potion are found in the book Moste Potente Potions (see) (CS9)
Before the last ingredient is added - the bit of the person being transformed into - the potion looks like thick dark mud and bubbles sluggishly (CS12), (HBP9)
When the last ingredient is added, the potion froths a great deal and changes colour, but the resulting colour varies depending on the person supplying the last ingredient (CS12)
isn't supposed to be used for transforming humans into animals (CS12); if misused for that purpose, results in an incomplete transformation requiring skilled medical treatment to undo (CS13)
Polyjuice Potion can be used for cross-gender transformations. Crouch Jr. used Polyjuice Potion to impersonate his mother in order to escape from Azkaban, while she used it to impersonate him (GF35). Crabbe and Goyle appear to have used it periodically during their sixth year to pass themselves off as much younger, smaller girls in order to be less conspicuous (HBP21).
Crouch Jr. used Polyjuice Potion to impersonate Moody, so it can account for missing limbs and scars as well as age differences (GF35)
Harry's O.W.L. written exam included a question about Polyjuice Potion. Harry felt that he'd very well with that question, since he'd taken the potion himself a couple of years before (OP31).
Judging from the Ministry of Magic leaflets on the subject, there appears to be no physical way of telling the drinker of Polyjuice Potion from the original. The only security measure recommended against Polyjuice Potion is to work out a prearranged method of verifying someone's identity, such as a password or a question that only the real person should be able to answer, but this system can of course be defeated by a sufficiently thorough and clever impersonator (HBP3).
The juice may be used in Strengthening Solution at some stage (see) and is definitely a potions ingredient.
The quills are used in boil-cure potion (see).
The eyes are used in Swelling Solution (see).
Ironically, Goyle caught a eyeful of this on the day the second-year students were making it, and his own eyes began swelling to the size of dinner plates (CS11).
