"Natural" doesn't really mean anything (basically if something exists, it's natural; I'm natural therefore I am...) but I threw that word in the title just to give you an idea of what this mouthwash is all 'bout. The ingredients are basic, maybe in your house already, and edible; though I do not recommend drinking this mouthwash. Firstly because it'd just taste REALLY minty and salty and sweet and strange. But also, after you gargle with it in your mouth, it is carrying a bunch of icky stuff that you want to spit OUT, not ingest.
