Eel eye

Eel eyes are eels' optical organs. They are used in potion-making. They might be an ingredient for the Bulgeye Potion. The Apothecary in Diagon Alley sells jars of eels' eyes for one Galleon each.

According to a painting at St Mungo's, one must stand naked in a barrel of eel's eyes at the full moon with a frog's liver tied tightly about one's throat to cure Spattergroit; the legitimacy of this claim remains somewhat unconfirmed.
