Smurf essence

Smurf essence is a substance created by Papa Smurf in the EMPATH: The Luckiest Smurf story series that has various magical properties, such as slowing the rate of aging and physical rejuvenation. It is mostly created from Smurf hair, which is provided by Barber Smurf when he is finished clipping his customers' hair. However, Papa Smurf tends to use his own beard clippings to create Smurf essence and not mix other Smurfs' hair with his own, which he feels would contaminate the essence and thus cause unknown effects.

Because Smurfs are highly sought after by wizards and witches who intend to use them for purposes regarding humans, Smurf essence is highly controlled by Papa Smurf and isn't given to anyone except to the few wizards he can trust such as Homnibus.
