What actually is inside magic mouthwash?

Magic mouthwash usually contains at least three of these basic ingredients: -an antibiotic to kill bacteria -an antihistamine or local anesthetic to reduce pain and discomfort -an antifungal to reduce fungal growth -a corticosteroid to treat inflammation -an antacid.
