======Potion Ingredients======
=====Introduction=====
**Potion Ingredients** are the various components, primarily of plant, animal, or magical origin, that are combined in a [[cauldron]] to brew [[Potions]]. The selection, preparation, and combination of these ingredients form the fundamental basis of [[Potions]] as a magical discipline. The properties of each ingredient are crucial, and their precise handling is often the key to a successful brew. This complex art is a core subject taught at [[Hogwarts School of Witchcraft and Wizardry]].
=====Sourcing and Preparation=====
Ingredients for potions are acquired from a variety of sources and require specific, often meticulous, preparation methods to unlock their magical properties.
  * **Sourcing:** Most ingredients can be purchased from an [[Apothecary]], such as [[Slug and Jiggers Apothecary]] in [[Diagon Alley]]. [[Hogwarts]] maintains a well-stocked student store cupboard for its [[Potions]] classes, though more valuable or dangerous ingredients are kept in the professor's private stores, such as those belonging to [[Severus Snape]] and later [[Horace Slughorn]]. Many plant-based ingredients are cultivated in greenhouses as part of [[Herbology]], while animal-based components are often by-products of creatures studied in [[Care of Magical Creatures]].
  * **Preparation:** The preparation of an ingredient is as important as the ingredient itself. Methods include dicing, slicing, crushing, stewing, and bruising. Professor [[Snape]]'s teaching style emphasized the //"subtle science and exact art"// of [[Potions]], demanding absolute precision from his students. The importance of preparation is famously highlighted in Harry's sixth year, when he follows the [[Half-Blood Prince]]'s instructions to crush a [[Sopophorous Bean]] with the flat of a silver dagger rather than cutting it, drastically improving the efficacy of his [[Draught of Living Death]].
=====Categories and Examples of Ingredients=====
Potion ingredients are immensely varied and can be broadly categorized by their origin. The following are notable examples mentioned in the novels.
**Plant-Based Ingredients**
  * [[Asphodel]]: The powdered root is a key ingredient in the [[Draught of Living Death]].
  * [[Belladonna]]: A poisonous plant whose essence is used in some potions.
  * [[Bubotuber]]: The pus is a treatment for severe acne but must be handled with gloves.
  * [[Dittany]]: A powerful healing herb used in the creation of [[Essence of Dittany]].
  * [[Fluxweed]]: Must be picked at the full moon to be used in [[Polyjuice Potion]].
  * [[Gillyweed]]: When eaten, allows a witch or wizard to grow gills and fins to breathe underwater.
  * [[Knotgrass]]: A component of the [[Polyjuice Potion]].
  * [[Mandrake]]: A plant with a root that looks like a human. Its cry is fatal to anyone who hears it, but the Restorative Draught made from mature Mandrakes can cure petrification.
  * [[Nettles]]: Dried nettles are a basic ingredient used in the [[Cure for Boils]].
  * [[Sopophorous Bean]]: A key ingredient in the [[Draught of Living Death]] that is difficult to prepare.
  * [[Wolfsbane]] (also known as [[Aconite]] or [[Monkshood]]): The primary ingredient in the [[Wolfsbane Potion]], which allows a werewolf to keep their human mind during transformation.
  * [[Wormwood]]: An [[Infusion of Wormwood]] is a powerful sleeping agent and a component of the [[Draught of Living Death]].
**Creature-Based Ingredients**
  * [[Armadillo]] bile: An ingredient in the [[Wit-Sharpening Potion]].
  * [[Bat]] spleens: An ingredient required for the [[Swelling Solution]].
  * [[Bezoar]]: A stone from the stomach of a goat that acts as an antidote to most poisons.
  * [[Bicorn]] horn: Powdered horn is a key ingredient for [[Polyjuice Potion]].
  * [[Boomslang]] skin: The shredded skin is an essential and difficult-to-obtain ingredient for [[Polyjuice Potion]].
  * [[Dragon]] parts: Various parts, including [[Dragon]] blood, heartstring, horn, and liver, are potent magical ingredients.
  * [[Jobberknoll]] feathers: Used in [[Truth Serums]] and [[Memory Potions]].
  * [[Lacewing flies]]: Must be stewed for twenty-one days before being used in [[Polyjuice Potion]].
  * [[Leeches]]: Used in [[Polyjuice Potion]] and the [[Shrinking Solution]].
  * [[Phoenix]] tears: A powerful healing substance, capable of reviving a person from the brink of death.
  * [[Rat]] tails: A component of the [[Hair-Raising Potion]].
  * [[Snake fangs]]: Crushed fangs are used in the [[Cure for Boils]].
  * [[Unicorn]] parts: The [[Unicorn]] horn and tail hair are valuable potion ingredients. [[Unicorn]] blood can keep a person alive but at a terrible cost.
**Other Magical Substances**
  * [[Moonstone]]: A mineral used in various potions, including the [[Draught of Peace]].
=====Role in the Story and Wizarding Society=====
Ingredients are central to the plot on numerous occasions. The quest undertaken by [[Harry Potter]], [[Ron Weasley]], and [[Hermione Granger]] to illicitly gather the components for [[Polyjuice Potion]] in their second year is a major storyline. This includes stealing [[Boomslang]] skin and [[Bicorn]] horn from Snape's private stores.
The value and rarity of certain ingredients are also significant. [[Unicorn]] horns and [[Bezoars]] are noted to be very expensive. Harry's use of a [[Bezoar]] to save Ron's life from poisoned mead demonstrates the practical, life-saving knowledge of ingredients. Furthermore, the tension between Harry and Snape is often heightened by Snape's frequent, and sometimes accurate, accusations of Harry stealing valuable ingredients.
=====Behind the Scenes=====
  * Many of the plant-based ingredients in the //Harry Potter// series, such as [[Belladonna]], [[Wolfsbane]] ([[Aconite]]), and [[Wormwood]], are drawn from real-world herbology and folklore, where they are often associated with magic, poison, and medicine.
  * The Pottermore (now Wizarding World) website and licensed video games have greatly expanded the list of known potion ingredients beyond those mentioned in the seven original novels. For example, Pottermore states that [[Ashwinder]] eggs and [[Occamy]] eggshells are required ingredients for [[Felix Felicis]], details which are not present in the books (Pottermore).
