Aging Potion

This causes the drinker to become older. Whether this is in body only or in body and mind, isn't clear. It is clear, however, that the more of the potion is drunk, the larger the aging which occurs. The effects of this potion are most likely to be temporary.

Amortentia

The most powerful Love Potion in the world, it causes a powerful infatuation or obsession in the drinker. It has a distinctive mother-of-pearl sheen, and steam rises from it in characteristic spirals. It has a different aroma to everyone who smells it, reminding each person of the things that they find attractive.

Anti-Poison Potion

This is an antidote to a variety of poisons. The Bezoar is used to combat most poisons, but not all of them.

Antidotes

Different antidotes exist for different effects. Known antidotes exist for Doxy bites, petrification, and of course, poisons.

Babbling Beverage

Causes the drinker to babble nonsense.

Boil-Cure Potion

Ingredients: Dried nettles, Crushed snake fangs, Stewed horned slugs and Porcupine quills. Cures boils. Little else is known about this, except that it is an elementary potion taught to first-years.

Baruffio's Brain Elixir

Increases brain power. Eddie Carmichael tried to sell a pint of this to Ron and Harry for 12 Galleons when they were revising for their OWLs, claiming that it was entirely responsible for him getting 9 “Outstanding” grades the previous year. Hermione confiscated the bottle and poured it down the toilet.

Beautifying Potion

This was invented by Sacharissa Tugwood, and makes the drinker more physically attractive. Whether this effect is temporary or permanent is unknown. As her epitaph says, “Thanks to Sacharissa Tugwood, the world is a more beautiful place”.

Befuddlement Draught

Ingredients: Scurvy-grass, Lovage, and Sneezewort. Causes the drinker to become fuddled, or confused. This may be the same potion as “Confusing Concoction” under a different name. [OP18]

Blood-Replenishing Potion

Tops up the blood levels of the drinker after injury.

Bruise Removal Paste

This is a thick yellow paste guaranteed to remove any bruise within an hour. It was invented by Fred and George Weasley, who found that as they had to test most of their joke shop products on themselves, a decent bruise remover was a necessity.

Burn-Healing Paste

Not exactly a potion, but a thick orange paste used to heal burns. Madam Pomfrey uses it on Cedric Diggory after the first task of the Triwizard Tournament.

Calming Draft

A potion that relieves stress and induces calm in the drinker. Hannah Abbot was given a Calming Draught by Madam Pomfrey after becoming so upset about her impending OWL exams that she burst into tears in Herbology.

Confusing Concoction/Confusing Draught

Ingredients: Scurvy-grass, Lovage, Sneezewort. Causes confusion in the drinker.

Deflating Draught

Causes anything swollen by magical means to shrink back to normal size. This is the opposite to a Swelling Solution and acts as an antidote to it.

Doxycide

This a black solution used to spray Doxies. It renders them unconscious for a time.

Dr. Ubbly's Oblivious Unction

A medicinal potion given to Ron by Madam Pomfrey after he had been attacked by brains in the Department of Mysteries. It proved effective in healing the injuries caused by the brains' tentacles and thoughts.

Draught of Living Death

Ingredients: Wormwood, Asphodel, Sopophorus Bean and Valerian Roots . This is an extremely powerful sleeping potion. Snape thought Harry should have read up on it in Magical Drafts and Potions before arriving for his first year at Hogwarts.

Draught of Peace

Ingredients: Powdered moonstone and Syrup of hellebore. Calms anxiety and soothes agitation.

Dreamless Sleep Potion

A medicinal potion, used to induce dreamless sleep in the drinker and aid recuperation.

Emerald Green Potion

A mystery potion that Lord Voldemort used to protect his locket Horcrux. It induces fear and delirium in the drinker, and is almost certainly highly poisonous. It has a highly debilitating effect on the drinker and will cause death if left untreated.

Elixir to Induce Euphoria

A sunshine-yellow potion and creates a feeling of euphoria in the drinker. Side-effects of excessive singing and nose-tweaking can occur on occasions, although adding a sprig of peppermint should help to counter-balance these.

Elixir of Life

This is produced by the Sorcerer's/Philosopher's Stone, and grants the drinker immortal life for as long as they keep on drinking it.

Essence of Insanity

A potion that Ron thought Harry might have taken instead of Felix Felicis.

Essence of Murtlap

Hermione gave this to Harry to help his hand heal after his detention with Umbridge and her revolting punishment quill. When Lee Jordan was given a similar detention later in the year, Harry recommended it to him as well.

Essence of Rue

A potion that Ron was prescribed by Madam Pomfrey to aid his recovery after he had been poisoned by Malfoy’s mead. [HBP19]

Everlasting Elixirs

Unknown, but presumably the effect is everlasting.

Exploding Potion

Ingredients: Erumpent fluid. The erumpent produces a remarkable fluid in its horn which causes anything it is injected with to explode. This is used in potion-making to produce an exploding potion.

Felix Felicis

Lady luck in liquid form. Felix Felicis makes the drinker lucky for a period of time, dependent on how much is drunk, during which time everything they attempt will succeed. It must be used sparingly, however, because if taken in excess it causes giddiness, recklessness and dangerous overconfidence. It is highly toxic in large quantities, and is also a banned substance in all organised competitions.

Forgetfulness Potion

Causes the drinker to become forgetful.

Gregory's Unctuous Unction

Makes a person drinking it think that whoever gave it to them is their best friend.

Hair-Raising Potion

Ingredients: Rat tails. Effect unknown.

Hiccupping Solution

Causes the drinker to hiccup.

Invigoration Draught

Effect unknown, but presumably it invigorates the drinker and increases energy levels. Harry had to make this in a 5th year Potions lesson. Snape had taken to ignoring him rather than bullying him at the time and so Harry’s effort was rather more successful than usual. [OP29]

Love Potion

Ingredients: Ashwinder eggs. Causes the drinker to fall in love. During his Valentine's Day event, Lockhart suggested that the students ask Professor Snape to knock up a quick Love Potion for them. Professor Snape did not approve. Weasleys' Wizard Wheezes sell their own range of Love Potions, which - as Ron can testify to - really do work.

Mandrake Restorative Draught

Ingredients: Mandrake. This is used to revive people who have been petrified. It was particularly useful when the Basilisk was released from the Chamber of Secrets and petrified a number of students.

Memory Potion

Ingredients: Jobberknoll feathers. The effect of this in not known, but it is likely that the potion is used to give the drinker improved access to their memories.

Mrs Scower’s Magical Mess Remover

Cleaning solution favored by Argus Filch.

Pepperup Potion This relieves the symptoms of colds and flu, although it doesn’t seem to actually provide a cure. It has the side-effect of causing steam to come out of the drinker’s ears for several hours after imbibing it.

Photograph Developing Fluid

Even though Colin Creevey has a Muggle camera, he was told that he could still produce wizard-style moving photographs by developing them in the correct fluid.

Polyjuice Potion

Ingredients: Fluxweed, Horn of bicorn, Knotgrass, Lacewing flies, Leeches and Skin of boomslang. This potion allows the drinker to assume the appearance of another person. The effect lasts for an hour, but as Bartemius Crouch Jr showed when impersonating Alastor Moody, repeat doses can be taken indefinitely. In addition to the standard ingredients listed, this potion also requires a part of the person you want to assume the appearance of. The fluxweed has to be picked at full moon, and the lacewing flies stewed for 21 days before the potion is made.

Protective Potions (Fake)

Ingredients: Bubotuber Pus and Gravy. Following the return of Voldemort, a vast market appeared for protective potions, most of which were fake and did nothing. Small-time crooks like Mundungus Fletcher sold them to the frightened hordes, who apparently didn't notice that they were often made out of gravy.

Scintillating Solution

Effect unknown. However, one satisfied customer of the Kwikspell course happily wrote to tell them that their recipe for this potion was now in great demand.

Shrinking Potion

Ingredients: Caterpillar, Daisy roots, Leech juice, Rat spleen, Shrivelfig. This a an acid green potion which is on the third year syllabus. Snape uses it to turn Neville’s toad into a tadpole; it is unclear whether the potion makes things simply reduce in size, or actually reduce in age.

Skele-Gro

This causes lost bones to re-grow, which is a slow and painful process. Harry only had his arm bones removed because of Lockhart’s incompetence; it seems unlikely that under other circumstances Skele-Gro has to be used very often.

Sleekeazy's Hair Potion

This is used to calm down problem hair so it can be styled. Hermione used liberal amounts of it when she went to the Yule Ball with Viktor Krum.

Sleeping Draught/Potion

Causes the drinker to fall asleep. A standard Sleeping Draught differs from the Draught of Living Death, which is a much more powerful version.

Strengthening Solution

Ingredients: Pomegranate juice and Salamander blood. Effect unknown, but presumably this potion makes the drinker stronger. It could, however, be designed for inanimate objects if the potion was intended to be applied to them. Harry made this potion (very badly) in a 5th year class whilst Snape was being assessed by Umbridge. Umbridge disapproved of teaching this particular potion to the students, and Snape took very little notice of her. [OP17]

Swelling Solution

Causes whatever it touches to swell up in size.

Ten-Second Pimple Vanisher

This comes in a small pink pot and is excellent on anything from boils to blackheads. It is sold at Weasleys' Wizard Wheezes.

Veritaserum

A powerful truth potion. It is used to make the drinker answer any questions put to them truthfully. Use is strictly controlled by the Ministry of Magic.

Wiggenweld Potion

Leticia Somnolens was a spiteful hag who was jealous of the king’s daughter and caused her to prick her finger on a spindle tainted with a Draught of the Living Death. A young wizard smeared his lips with Wiggenweld Potion, kissed the princess, and brought her out of her trance.

Wit-Sharpening Potion

Ingredients: Scarab beetles, Ginger roots, Armadillo bile. The effect of this is not known, although it is likely to involve sharpening the wit of the drinker (in other words, making them able to think better).

Wolfsbane Potion

A new and complex potion, this relieves the symptoms of lycanthropy (although it does not cure it). If the affected person drinks the potion at full moon, they transform only into a normal wolf (and retain control over their actions) rather than bloodthirsty out-of-control werewolf.

Wound-Healing Potion

This is a smoking purple liquid which heals and closes open wounds. Madam Pomfrey uses it on Harry when he has been injured during the first task of the Triwizard Tournament.
