This work constitutes an approach to the complex world of medical pluralism during the modern age. First, there is a review of the recent historiography concerned with recovering all the possible medical resources that existed and were offered to the patient. The complexity of this medical world are then described, noting the persistence of some elements throughout the late medieval and early modern period. Within the theoretical framework and historical setting established, the work concludes by showing the complexity and permanent interrelationship in the care options, from the point of view of private correspondence of the Veciana family at the end of the XVIII century.
