From Popular Medicine to Medical Populism presents the history of medical practice in Costa Rica from the late colonial era - when none of the 50,000 inhabitants had access to a titled physician, pharmacist, or midwife - to the 1940s, when the figure of the qualified medical doctor was part of everyday life for many of Costa Rica’s nearly 1,000,000 citizens. It chronicles the history of all healers, both professional and popular. Steven Palmer breaks with the view of popular and professional medicine as polar opposites - where popular medicine is seen as representative of the authentic local community and as synonymous with oral tradition and religious and magical beliefs and professional medicine as advancing neocolonial interests through the work of secular, trained academicians. Arguing that there was significant and formative overlap between these two forms of medicine, Palmer shows that the relationship between practitioners of each was marked by coexistence, complementarity, and dialogue as often as it was by rivalry. Palmer explains that while the professionalisation of medical practice was intricately connected to the nation-building process, the Costa Rican state never consistently displayed an interest in suppressing the practice of popular medicine. In fact, it persistently found both tacit and explicit ways to allow untitled healers to practice. Using empirical and archival research to bring people (such as the famous healer or curandero Professor Carlos Carbell), events, and institutions (including the Rockefeller Foundation) to life, From Popular Medicine to Medical Populism demonstrates that it was through everyday acts of negotiation among agents of the state, medical professionals, and popular practitioners that the contours of Costa Rica’s modern, heterogeneous health care system were established.
