In urban bathhouses in Germany and the surrounding low countries, bathhouse proprietors, known as baders, provided visitors with basic medical care. To draw blood, baders would scratch the skin before placing a heated cupping glass over the incision to extract blood and purge the body. Other tools associated with baders, including dental forceps and an amputation saw, hint at further services they provided.
