In early modern England, tiny worms were thought to cause tooth cavities, jaundice was a disease rather than a symptom, and those unlucky enough to become ill could find themselves subjected to 'cures' such as skin blistering and bloodletting. Drawing on contemporary sources including physicians' and apothecaries' notes, medical treatises and personal journals, this book explores how doctors dealt with common complaints and how sufferers responded to diseases and their treatment.
