Diversity of Medicinal Plants Used by the Local Communities of the Coastal Plateau of Safi Province (Morocco)

Abstract

Traditional herbal medicine is still used for basic healthcare by a significant portion of the population in developing countries. This study aimed to explore the medicinal plant’s diversity and to document related traditional knowledge in the Safi region of Morocco. We used semi-structured questionnaires to interview 222 informants living in the study area. To perform data analysis, we used quantitative indices like use value (UV), family use value (FUV), fidelity level (FL), the relative popularity level (RPL), rank of order priority (ROP), and informant consensus factor (ICF). We reported the ethnomedicinal uses of 144 medicinal plants belonging to 64 families. According to the findings, the dominating families were Lamiaceae (17 taxa), Asteraceae (15 taxa), and Apiaceae (12 taxa). The most commonly utilized plant part (48%) was leaves. The decoction was reported as the main preparation method (42%). Highly cited plant species were Marrubium vulgare (UV = 0.56), Salvia rosmarinus Spenn. (UV = 0.47), Thymus serpyllum (UV = 0.32), and Dysphania ambrosioides (UV = 0.29). Papaveraceae (FUV = 0.26), and Urticaceae (FUV= 0.23), Geraniaceae (FUV = 0.17), Oleaceae (FUV = 0.17), Lamiaceae (FUV = 0.17) had the highest family use-values. Gastrointestinal disorders (88%), respiratory diseases (85%), and anemia (66%) have the greatest ICF values. This study reveals the indigenous people’s reliance on plant-derived traditional medicine to prevent, alleviate, and treat a broad range of health concerns. Our findings will provide a scientific basis for ethnomedicinal legacy conservation and further scientific investigations aimed at new natural bioactive molecules discovery.
