Ethnopharmacological survey of plant species used in folk medicine against central nervous system disorders in Togo

Abstract

Ethnopharmacological relevanceNeurological diseases are rising all around the world. In a developing country such as Togo, although plant-based medicines are the only means, still very little is known regarding the nature and efficiency of medicinal plants used by indigenous people to manage central nervous system (CNS) disorders. Aim of the studyThis study, an ethnobotanical survey, aimed to report plant species used in traditional medicine (TM) for the management of various CNS disorders in Togo. Materials and methods52 traditional actors (TA) including 33 traditional healers (TH) and 19 medicinal plant sellers (MPS) were interviewed, using a questionnaire mentioning informants' general data and uses of medicinal plants. ResultsThe present study reports 44 medicinal plant species distributed into 26 families, mentioning scientific and common local names, plant organs used, preparation method, root of administration and putative applications. ConclusionIt appears that there is a real knowledge on medicinal plants used for traditional treatment of CNS disorders in Togo and that the local flora abounds of potentially neuroactive plants which could be useful for the discovery of antipsychotic or neuroprotective molecules.
