======Cowbane======
=====Object Information=====
  * **Type:** [[Magical Plant]], [[Potion Ingredient]]
  * **Primary Use:** Ingredient in the [[Shrinking Solution]]
  * **Part Used:** Sprig
=====Description and Appearance=====
Cowbane is a magical plant used in [[Potions]]. The precise appearance of the magical variety of Cowbane is not described in the novels, but the use of a "sprig" suggests it is a leafy or herbaceous plant. Its real-world counterpart, also known as water hemlock, is a green, flowering plant with fern-like leaves, and it is highly toxic.
=====Magical Properties and Usage=====
The primary known magical property of Cowbane is its function as a key ingredient in the [[Shrinking Solution]], a [[potion]] that causes the drinker to shrink in size.
In the standard brewing instructions for the [[Shrinking Solution]], one sprig of Cowbane is added at a late stage in the process. It is added after the mixture has simmered for five minutes with ingredients such as [[rat spleen]], [[leech juice]], and pickled [[newt eyes]]. The addition of Cowbane is likely crucial for activating or completing the shrinking effect of the [[potion]].
=====Role in the Story=====
Cowbane is mentioned specifically in the context of [[Harry Potter]]'s [[Potions]] education. During his fifth year, the brewing of a [[Shrinking Solution]] was part of the practical portion of the [[Ordinary Wizarding Level]] (O.W.L.) exam.
In his sixth year, while trying to identify the ingredients of a complex blended [[potion]] in [[Horace Slughorn]]'s class, [[Harry Potter]] recalls the recipe for the [[Shrinking Solution]] from his exam. He remembers the specific instruction to "add one sprig of cowbane" as one of the final steps, highlighting the detailed knowledge required for even standard school-level [[Potions]]. This is its only mention in the original series.
=====Behind the Scenes=====
  * In the real world, Cowbane (//Cicuta maculata//) is a highly poisonous plant, also known as water hemlock. Its inclusion as a [[potion ingredient]] is consistent with the dangerous nature of many substances used in [[Potions]], where a single misstep can lead to disastrous results.
  * In the mobile video game *Harry Potter: Hogwarts Mystery*, Cowbane is an ingredient used in several potions, including the [[Swelling Solution]]. This usage is exclusive to the game. (video game)
