We describe two cases of impaired secondary renal function to a Carapa Procera taking as part of traditional treatment in
Ziguinchor, southern Senegal. The certain or suspected toxicity of Carapa Procera is little known in the literature. In the two reported
observations, no cause but the traditional treatment was found to explain the clinical picture presented. The development was
favourable in all cases after medical treatment and a few hemodialysis sessions. we insist on the difficult context of investigation
of these accidents, on the medical ignorance of these practices in sub-Saharan Africa and in Senegal in particular, as well as on the
necessary collaboration with local botanists knowledgeable in traditional medicine.
