The early modern household was a bustling site for a range of medical activities from self-diagnosis and medication to nursing and caring for the sick to drug production. To further their knowledge about medicine and the body, householders accessed a wide variety of sources. Many turned to their family and friends for health-related advice, consulted medical practitioners of various sorts, and avidly read the abundance of printed medical books offered by contemporary book producers. By the mid-seventeenth century, the bookshops near St. Paul’s in London were stocking an astonishing array of English medical books. Readers could pick and choose from an assortment of herbals, pharmacopoeias, general medical guides, surgical handbooks, midwifery manuals, regimens, medical recipe books, and more. These texts were eagerly consulted by householders, who utilized the knowledge contained therein not only for their home-based medical activities but also as a way to inform their decisions as actors in medical encounters with practitioners of all sorts.
