Database Economic value, endogenous knowledge and distribution of Picralima nitida (Stapf) T. Durand & H. Durand in Africa. 2020. Ethnobotanical and Geospacial data

This dataset on Picralima nitida species was collected in two climatic zones of West Africa. It regroups the ethnobotanical data presented in sheet 1 and geospacial references presented in sheet 2 and 3. Picralima nitida (Apocynaceae) is an important African medicinal plant species. It is very used in traditional medicine and pharmaceutical industries for manufacture of drugs against infectious diseases, malaria, diabetes and cancer. Despite its important, the species becomes rare, especially in the Dahomey Gap in contrast to the Guineo-Congolese region. There is also a controversy on its distribution. To ensure the sustainable use of this species, this study evaluated the economic value, endogenous knowledge and the effect of climate gradient on the distribution of the species in Africa.
