What is the real meaning behind the "eye of newt" in witchcraft practices?

In witchcraft practices, the "eye of newt" is a symbolic ingredient often used in spells and potions. It represents the idea of using natural elements and ingredients in magic rituals, rather than being a literal eye of a newt. The phrase is more about the symbolism and tradition of using specific ingredients in witchcraft rather than the actual physical presence of a newt's eye.
