The youth potion was a blue liquid that Hagatha was brewing in order to regain her beauty. She needed a Nightingale in order to complete it. Graham acquired the bird for Angelina, who beat Hagatha to the punch. When Hagatha found out, she dealt with Angelina severely. When she found the potion, it fell through a hole in the floor where Graham was hiding underneath. Graham picked it up and carried it with him for a large portion of his quest until entering the Tower Realm. After dealing with the lion in front of the tower door, Graham stuffed a tuft of cat fur into the potion. When Hagatha took it, she regained her youth but took on a cat-like appearance. Graham finally knocked Hagatha out of the window with the dresser mirror.
