"This is the most complicated potion I've ever seen. Lacewing flies, leeches, fluxweed, and knotgrass. Well, they're easy enough."

— Hermione Granger on the ingredients of the Polyjuice Potion

Fluxweed was a magical plant and member of the mustard family known for its healing properties.

Description

When picked at the full moon, it could be used in the making of the Polyjuice Potion. Sixteen scruples were needed to make the potion.

History

When trying to persuade Professor Severus Snape to attend Rubeus Hagrid's surprise birthday party in 1984 by gifting him potion ingredients, Jacob's sibling found fluxweed in the Artefact Room at Hogwarts School of Witchcraft and Wizardry with help from Ben Copper and Penny Haywood.

During the 1989–1990 school year at Hogwarts School of Witchcraft and Wizardry, sixth year Herbology students were taught about this plant by Professor Pomona Sprout.

Etymology

The word Flux means constant change or flow, so it makes logical sense that it would be an ingredient in Polyjuice Potion.

Behind the scenes

• The use of fluxweed in the Polyjuice Potion was chosen by J. K. Rowling to represent "the mutability of the body as it changed into another".
