Troll Whiskers

• Type: Potion Ingredient, Magical Creature Part
• Owners: Stocked by apothecaries, such as the Apothecary in Diagon Alley, and kept in the student store cupboard in the Hogwarts Potions Classroom.
• Maker: Harvested from a Troll.

While not explicitly described in the original novels, Troll Whiskers are presumed to be thick, coarse, and wiry hairs obtained from a Troll. Given the notoriously poor hygiene and foul smell of Trolls, their whiskers likely carry a similar unpleasant odor. They are a standard ingredient used in Potions. In film adaptations, they are seen stored in glass jars as dark, wiry clumps (film).

The primary magical property of Troll Whiskers is to impart strength, reflecting the brute force of the creature from which they are harvested. Their main use is as a key ingredient in potions designed to increase the physical power of the drinker.

• Strengthening Solution: Troll Whiskers are a known ingredient in some variations of this potion, which fortifies the user (Harry Potter and the Chamber of Secrets (video game)).
• Strength Potion: They are also listed as an ingredient for a general Strength Potion (Pottermore).

The process of incorporating them into a potion likely involves dicing or crushing to release their magical properties into the brew.

Troll Whiskers do not have a specific, documented history as a unique object but are rather a long-established commodity in the Wizarding world. Their use in strengthening draughts is part of the standard Potions curriculum taught at Hogwarts, indicating they are a commonly accepted and utilized ingredient. Though Harry Potter and his friends encounter a Troll during their first year at Hogwarts, the narrative never depicts the harvesting of whiskers or their use in any of the specific potions brewed in Professor Snape's or Professor Slughorn's classes within the seven novels.

Troll Whiskers are not mentioned in the narrative of the seven original *Harry Potter* novels. Their existence is part of the expanded magical world, serving as a background element that enriches the lore of Potions and the use of magical creature parts in magic. They help to illustrate the practical, and sometimes grisly, sourcing of ingredients required for potion-making.

• Film Adaptations: Prop jars explicitly labelled “Troll Whiskers” are visible as set dressing in the Hogwarts Potions Classroom in the Warner Bros. films, establishing their presence within the film's version of the Wizarding world.
• Video Games: Troll Whiskers appear as a collectible ingredient in several video games. In Harry Potter and the Chamber of Secrets (PC video game), they are a required ingredient for the Strengthening Solution. They are also a creature material that can be collected in Hogwarts Legacy (video game).
• Pottermore/Wizarding World: The official website lists Troll Whiskers as an ingredient in the Strength Potion, solidifying their function in the wider canon.
