Abstract

|
Hypertension is a global public health problem. This study aimed to determine the diversity of plant species used by traditional healers. Thus, semi-structured interviews were carried out with 195 informants through traditional healers associations of Sanmatenga, Bazega and Zounweogo located in different phytogeographical sectors. Questionnaire referred mainly to plants vernacular names, organs used and recipes formulation. Citation frequencies and use values were calculated for each plant. Data were then submitted to comparison tests and multivariate statistics in R program. Traditional healers of Sanmatenga, Bazega and Zounweogo used respectively 70 species, 64 and 88 species for the hypertension management. However, the Jaccard index of similarity showed that there was no similarity between three associations demonstrating the importance of climatic gradient in the availability of species used. The age, sex and association belonging traditional healer did not influence species richness but, were determinants for use patterns of the plant. These results show that a sociodemographic parameter alone cannot be decisive for several local knowledge at once, but rather the interaction with other factors. Thus, the sustainable use of plant resources by the traditional healers recommends that the effects of this interaction of the various factors be taken into account.
