Which of the following practices were historically performed by barber-surgeons?

Historically, barber-surgeons played a unique role that combined elements of both barbering and surgical practices. They were skilled in various procedures, notably bloodletting, tooth pulling, and performing minor surgeries. During the Middle Ages and Renaissance periods, barbers were among the few individuals trained to handle medical procedures, as formal medical education was limited and not widely available. Their specialized training allowed them to perform surgeries, such as lancing abscesses, and engage in practices like bloodletting, which was believed to balance bodily humors and restore health.

This combination of skills harkens back to a time when the separation between barbering and surgical practices was not distinctly defined, thus emphasizing the multifaceted roles barber-surgeons had within their communities. The other choices primarily focus on standard grooming services, which were indeed part of a barber's job but do not encompass the medical and surgical responsibilities historically associated with barber-surgeons.
