​To discuss pharmaceutical anthropology requires moving beyond the traditional distinction between folk remedies and standard modern medicines, toward studying them all the same way. The biographical approach to objects helps in understanding the various transformations and interactions that govern a medicine in a given temporal and social context. This article traces the life story of Aureomycin in Morocco, from the contexts in which it appeared, through its physical production, marketing and distribution processes, and finally its consumption. It becomes evident that the medicine is not used in the way that producers expect; rather, it is subjected to the logic of “pharmaceutical heretics” who treat Aureomycin as folk medicine and part of new, intermediary treatment process – one that is neither wholly modern nor traditional.
