Those whose titles appear in bright green are named in the books. The others are referred to but not named. Ingredients are listed where known, but even if Muggles would gather and brew the correct herbs, insects, and other materials (some of which are poisonous), they would not be able to create the potions listed here. The most important ingredient to any magic is the magical power of the wizard creating the effect.
