Ethnopharmacological survey of aromatic and medicinal plants of the pharmacopoeia of northern Morocco

Abstract

Backgound: For centuries, Moroccan herbalists have been using traditional plant-based medicines; however, most of these traditional healers misuse their use because of the limited information about harmful side effects. The traditional healers prescribe recipes that do not comply with any quality standards. Materials and methods:This study was designed and initiated in an effort to classify and shortlist the most reported medicinal plants used by traditional healers in the northern part of Morocco and identify their associated toxicities. Data from this work was obtained by collecting semi-interviews and direct questionnaires from local traditional healers and guided fieldtrips with herbalists.Results: A total of 40 of the identified plant species belonged to 34 genera and 21 botanical families. The most represented were Lamiaceace (13 species) followed by Asteraceace (6 species) and Cupressaceae (3 species). The most frequently cited and used species were Mentha pulegium (22.5%) and Rosmarinus officinalis (15%). In addition, our survey revealed 11 recipes prepared from 40 species. Leaves were the most used parts with a percentage of 30.52% and the main preparation method was infusion (63%). It shows that these recipes are generally administered orally during seven, fifteen or even thirty days with an average of one to three cups a day. Some of these recipes are used to treat diseases of the digestive and nervous system. The local population, whose purchasing power is very low, uses the plants harvested directly in the study area causing the disappearance of the most vulnerable species.Conclusions: This study shows that traditional medicine is still used and constituted a very rich heritage in northern Morocco. Further investigation of the benefits and risks of these plants will be needed to guide ancestral knowledge during selfmedication that causes negative effects on human health and will be needs planned exploitation.

Ethnobotanical survey of medicinal plants in Taounate, Pre-Rif of Morocco

“…For the other parts (whole plant, bulb, bark, rhizome), they are represented by a cumulative PPV=0.115 (Figure 5). Although these results show some similarities with those of (Salhi et al 2010;Labiad et al 2020), they are in contrast with those of (Mechchate et al 2020) who show that seeds are the most frequently used parts with a percentage of 33%. Indeed, the use of leaves is explained by the fact that they are easy to harvest, and that they constitute the centre of photosynthesis and storage of secondary metabolites responsible for biological properties (Tahri et al 2012;Slimani et al 2016).…”

Chemical Composition and In Vitro Antioxidant and Antimicrobial Activities of Marrubium vulgare L.

“…Medicinal and aromatic plants (MAP) are known for their use in the treatment of different diseases and as food additives [ 4 , 5 ]. They are rich in bioactive molecules with health benefits such as antioxidants and polyphenols [ 6 , 7 ].…”

“…In addition, the leaves of M. viridis have been used against gastric disorders by decoction, and the stems are used against ailments of intestines [ 2 , 23 ]. M. viridis whole plant infusions are also used to treat aphrodisiac, cold, flatulence, headache, tonic, and toothache [ 19 , 22 ]. In another study in Morocco, the powder from the leaves of M. viridis is used to treat skin diseases [ 21 ].…”
