What is Fermented Spider Eye in Minecraft?

A fermented spider eye is a strange, bubbly version of a regular spider eye. It is a very powerful and important ingredient for brewing potions. You cannot eat it, and it has no use on its own. Its only purpose is to be used in a brewing stand to create potions with negative effects, or to corrupt existing potions and flip their effects. For example, it can turn a Potion of Healing into a Potion of Harming. This makes the fermented spider eye an essential item for any alchemist who wants to create weapons or debuffs to use against their enemies.
