Traditional medicine in Benin has evolved, and this poses the problem of the relationship between traditherapy and the intercultural dynamics that our societies face in the face of "modernization. The results obtained show that with the valorization, certain practices and representations related to traditional medicine in this center are out of phase with the social and cultural logics that found traditional medicine. These breaks imply a weakening of the socio-cultural basis of endogenous medicine and testify to a logic of scientific legitimization of traditional medicine. In addition, certain socio-cultural logics specific to endogenous medicine are safeguarded thanks to the tradithérapeutes' room for manoeuvre, while others are perpetuated by undergoing transformations. Important innovations are at work in the traditional medicine practiced in this center. These innovations are both technical and organizational in nature and testify to the creative imagination deployed in thishospital to adapt the remedies used to the requirements of an increasingly Westernized clientele.
