Ethnobotanical and ethnopharmacological studies of medicinal and aromatic plants used in the treatment of metabolic diseases in the Moroccan Rif

Since early times, the people of Morocco use medicinal and aromatic plants as traditional medicine to heal different human ailments. However, little studies have been made in the past to properly document and promote the traditional knowledge. This study was carried out in the Rif (North of Morocco), it aimed to identify medicinal and aromatic plant used by the local people to treat metabolic diseases, together with the associated ethnomedicinal knowledge. The ethnomedical information collected was from 582 traditional healers using semi-structured interviews, free listing and focus group. Family use value (FUV), use value (UV), plant part value (PPV), fidelity level (FL) and informant agreement ratio (IAR) were employed in data analysis. Medicinal and aromatic plant were collected, identified and kept at the natural resources and biodiversity laboratory, Ibn Tofail University, Kenitra. During the present study 30 medicinal plant species belonging to 14 families has been documented. The most frequent ailments reported were diabetes (IAR = 0.98). The majority of the remedies were prepared from infusion (53.9%). Leaves were the most frequently used plant part (PPV 0.633) and Rosmarinus officinalis L. (UV = 0.325) was the specie most commonly prescribed by local herbalists. The results of this study showed that people living in the Rif of Morocco are still dependent on medicinal and aromatic plants. The documented plants can serve as a basis for further studies on the regions medicinal plants knowledge and for future phytochemical and pharmacological studies.
