Halitosis, or bad breath, is bothersome and embarrassing. It affects nearly 50 percent of the general population1 and may originate either from your mouth or a non-oral source. Mouthwash has become the treatment option many turn to in order to relieve their symptoms.
Interestingly, early historical documents show the Romans would import bottled Portuguese urine to kill oral bacteria.2 The practice was so common that Nero placed a tax on the import. Urine remained a primary ingredient in mouthwash until the 18th century. In the 19th century alcohol replaced urine to kill germs.
