Wrinkleroot is a plant substance that is used for magic potions and spells

Mainstream Smurfs Media

In mainstream Smurfs media, Papa Smurf needed to get wrinkleroot for one of his experiments, so he left his little Smurfs to take care of important village tasks while he was gone on a trip to get some more in the cartoon version of "King Smurf". (In the original comic book version, the substance that Papa Smurf needed was called euphorbium.)
