Modern Snake Oil

At the end of the 1800s and the start of the 1900s people pushed cure alls that are commonly called snake oils. Eventually as scientific rigor and testing became more important most of these were pushed out of the market by people not believing that these cure alls actually work because they had not been scientifically tested. This did not get rid of them all, however, and new ones pop up from time to time. C0nc0rdance has a great video up about one such snake oil, although he refers to it as Windex Syndrome (you do have to enjoy the My Big Fat Greek Wedding reference), that involves bleach.
