During medieval times, barbers also functioned as doctors and dentists, performing surgeries, bloodlettings, and tooth extractions. The original barber’s pole had brass basins at the top and bottom, representing the vessel that held the leeches used in bloodletting procedures and the one that received the blood. The pole itself represents the staff patients gripped to encourage blood flow, while its red and white stripes symbolize bandages. What does the blue stripe on US barber poles represent? Discuss
