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