Up until the late 19th century barbers also acted as back-street surgeons. People with little money who were in need of treatment would go to the barber who would perform operations including tooth extraction and amputations. The symbol of the red and white striped pole which marks a barber shop is a reference to this forgotten aspect of their trade - it represents a bone wrapped in blood-soaked bandages.
