Causes the target person to talk nonsense.
In an effort to pass along a warning to Snape, Harry once shouted "He's got Padfoot in the place where it's hidden." Snape pretended not to know what Harry was talking about and said that if he wanted to hear nonsense, he'd give Harry a Babbling Beverage (OP32)
Beautifying Potion / Beautification Potion
Potions to make the drinker more lovely in appearance.
Sacharissa Tugwood was an expert at these potions, pioneering their creation and use (fw)
The famous hag Malodora Grymm, using a beautification potion to conceal her true form (fw).
See CONFUSING AND BEFUDDLEMENT DRAUGHTS.
This substance presumably causes the target creature to belch.
Evidently a Zonko's product sold in Hogsmeade, and definitely one of the many, many items Filch does not like having in the castle (PA8)
Essence of this poisonous plant is part of a student's standard potion-making kit (GF10).
(PS8, GF22)
A shriveled, kidneylike "stone" (HBP18) that comes from the stomach of a goat, protects from most poisons (PS8)
Actually a bezoar isn't a stone per se, but a hairball that looks something like a stone; in legend bezoars are indeed supposed to have the properties attributed to them by JKR.
bicorn parts
Powdered horn used in Polyjuice Potion.
Billywig parts
Dried stings (FB)
See cockroaches.
Medical magic: this potion makes up for lost blood.
Arthur had to take a Blood-Replenishing Potion every hour until the Healers could find an antidote for the venom of the snake that bit him. Something in that venom was keeping the wound open and he was bleeding whenever they would remove the bandages (OP22)
ingredients: dried nettles, crushed snake fangs, stewed horned slugs, porcupine quills (added after taking the cauldron off the fire)
Simple potion to cure boils.
Taught to first-years in their first Potions class with Snape (PS8)
If the porcupine quills are added before the cauldron is taken off the fire, the mixture produces clouds of acid green smoke and a loud hissing, melts the cauldron, and burns holes in people's shoes. This happened to Neville, who was splashed by it and sprouted angry red boils (PS8)
boomslang parts
Shredded boomslang skin is used in Polyjuice Potion. See also snake parts more generally.
Medical magic: this is a thick yellow paste used to heal bruises.
The twins gave some to Hermione to treat the bruises caused by their prototype punching telescope (HBP6)
The pus of a bubotuber, properly processed, is useful in treating acne.
The pus of a bubotuber is yellowish and smells of petrol (GF13)
The pimple-curing properties of bubotuber pus were discovered by Sacharissa Tugwood (fw/68)
Substance which causes the skin of a person who touches it to break out in boils
Fred Weasley put this in Kenneth Towler's pyjamas during their O.W.L. year (OP12).
Bundimun secretion
Diluted, this is used in some magical cleaning solutions.
Medical magic: this is an orange paste is used to heal burns.
Used by Madam Pomfrey to tend to burns during the Triwizard Tournament (GF20)
