- "Harry started unwrapping the shopping. Apart from The Standard Book of Spells, Grade 4, by Miranda Goshawk, he had a handful of new quills, a dozen rolls of parchment, and refills for his potion-making kit — he had been running low on spine of lionfish and essence of belladonna."

Spine of Lionfish is the long and separated vertebrae of the Lionfish. These spines are either used whole, or crushed into a powder. They can be used in the brewing of healing potions, such as the Wiggenweld Potion, and is also an ingredient of the Herbicide Potion. The ingredient can be bought from some shops, notably The Apothecary in Diagon Alley, at 2 Galleons for 16 bottles.
