Hair-Raising Potion

Few details are known about Hair-Raising Potion. As the name suggests, the potion causes the imbiber’s hair to stand on end. That’s about it.

Oh, and one of the ingredients is an unspecified number of rat tails. No one knows why, and we’re all happier that way.

Much happier.

Polyjuice Potion

Polyjuice Potion is an alchemical preparation that allows a human drinker to temporarily assume the form of another person – although only a particular person. In particular, it cannot be used to take the form of any non-human – although numerous attempts have ended in the potion drinker being stuck in some sort of in-between form.

The potion is a difficult and time-consuming one to prepare – among other things, it needs to brew for a month after its final brewing – and one of the most difficult to acquire ingredients is a sample of the target person, usually hair, although other substances will work just as well. Polyjuice Potion is also highly variable in the duration of its effect, with the quality of the numerous ingredients and the skill of the brewing both influencing the outcomes.

Fire Protection Potion

Fire Protection Potion – also known as Ice Potion – is a potion that protects the imbiber from the effects of naked flames, whether natural or magical. It is generally purple or black in colour, and known ingredients of the potion include bursting mushrooms, salamander blood and wartcap powder, although it is clear that there are other ingredients in addition to these.

When drunk, Fire Protection Potion gives the imbiber intense chills, sometimes described as feeling like ice flooding their body. Its effects are relatively short lived, but near to absolute while they last.

Deflating Draught

The Deflating Draught is probably best known as an antidote to the Swelling Solution. As such, it is a standard medical treatment in the wizarding world, used to reduce swellings of all kinds, whether they are magically induced or not.

Rumours that it can be used as a kind of magical viagra remain unconfirmed.

Elixir of Life

The Elixir of Life is a potion that prevents aging, although regular drafts of it must be taken or it will wear off. It can also be used in certain circumstances to recreate a body for those who have misplaced theirs through poorly applied magic.

Created by the alchemist Nicholas Flamel through the use of the Philosopher’s Stone, it is unclear whether or not there remains another means of creating it now that the Stone has been destroyed, or whether the remaining supplies of it are all there is.

Prohibition and Harry Potter

It may not seem like an apropos mix, but bear with me. After all, one can prohibit just about anything. Even in actual Prohibition, it could be argued what the actual thing intended to be prohibited was: a substance (alcohol), a state (drunkeness) or an activity (carousing).

But not to stray too far from either source material, I’ll assume that what’s prohibited at Hogwarts (and allied venues) are certain kinds of alchemical potions.
