This subtle and powerful ethnography examines African healing and itsrelationship to medical science. Stacey A. Langwick investigates the practices ofhealers in Tanzania who confront the most intractable illnesses in the region, including AIDS and malaria. She reveals how healers generate new therapies and shapethe bodies of their patients as they address devils and parasites, anti-witchcraftmedicine, and child immunization. Transcending the dualisms between tradition andscience, culture and nature, belief and knowledge, Langwick tells a new story aboutthe materiality of healing and postcolonial politics. This important work bridgespostcolonial theory, science, public health, and anthropology.
