Background: Diabetes mellitus is a major public health problem in Morocco with more than 1.6 million cases of diabetes in 2017 with an expectation to rise to over 2.7 million cases in 2045. The aim of this work is to provide ethnobotanical information on some of the medicinal plants used by diabetic patients to treat their illness in the region of Fez-Meknes (Morocco).
Methods:A semi-structured and simple questionnaire was carried out. A total of 422 interviews were conducted with diabetic patients presented to diagnosis in the Hassan II Hospital center in Fez in Morocco. The data were analyzed through use value (UV) and relative frequency of citations (RFC).Results: In total, 50 plant species belonging to 27 families were reported. Lamiaceae (14%), Apiaceae (12%) and Fabaceae (12%) were reported as the most represented families. Among the collected species, 6 plants were reported for the first time as antidiabetic plants in Morocco. The most frequently cited plant species are Trigonella foenum graecum (8.41%), Olea europaea (7.71%) and Prunus amygdalus var. amara (7.71%). Almost 67% and 33% of diabetic patient use medicinal plants as a complement and alternatives to their medication respectively.
Conclusion:This study showed the importance of medicinal plants in the healthcare system for treating diabetes. Knowledge of the use of medicinal plants that are used to manage diabetes may contribute to their preservation and to undertake further pharmacological studies.
Background: In Morocco, acute digestive system problems appear to be a famous daily ill which the most population deal with using medicinal plants. This work aims to inventory the plants used to deal with acute digestive system problems in the region of Fez-Meknes.Methods: A survey was carried out by means of a semi-structured questionnaire. A total of 423 interviews (108 of them are traditional health practitioners) were conducted. Botanical information about identified plants was carefully collected. Data were analyzed through the relative frequency of citation (RFC).Results: All respondents informed about the effectiveness of the medicinal plants and confirmed successful multiple uses of them. In total, 50 species belonging to 23 families were reported. The mostreported plant families were Lamiaceae (12 species), Apiaceae (10 species), Fabaceae, and Asteraceae (5 species). The most frequently used plants to treat digestive system acute problems based on their RFC values were: Foeniculum vulgare (8.58), Carum carvi (5.11) Glycyrrhiza glabra (4.56) Ammondaucus leucotrichus, Trigonella foenum-graecum, (4.20), Coriandrum sativum (4.01). The use of medicinal plants in the acute digestive system problems, according to the interviewed people, concerned six categories: Acute ache, digestion problems, intestinal comfort, bloating, diarrhea, and constipation.
Marjoram (Origanum majorana L.) infusion has been used as folk medicine against depression and anxiety. However, no studies have been carried out yet to prove those activities scientifically. In this study, the anxiolytic, antidepressant-like effects, and memory impact of the hydro-ethanolic extracts of marjoram were evaluated in mice. The hydro-ethanolic extracts (250 and 500 mg/kg) were evaluated for their central nervous effect using six different behavioral tests such as light–dark box (LDB) and open field (OF) for anxiety, forced swim test (FST), and tail suspension test (TST) for depression, and object recognition test (ORT), Morris water maze (MWM) for the impact on memory. The experiments were realized on days 1, 7, 14, and 21 of treatments and compared with bromazepam for anxiety (1 mg/kg) and paroxetine for depression (11.5 mg/kg). The phytochemical screening was performed by HPLC, and the acute and sub-acute toxicities were performed following OCED guidelines (N°423 and 407) with biochemical parameters evaluation and histopathological analysis. Oral administration of marjoram hydro-ethanolic extract induced significant anxiolytic and antidepressant-like effects without memory impairment, increasing the exploration and time spent in the light area in the LDB test in a similar way to that of bromazepam. In the FST and TST, the extract was as effective as paroxetine (11.5 mg/kg, p.o.) in reducing immobility. The phytochemical screening showed the presence of ferulic acid, naringin, hydroxytyrosol, geraniol, and quercetin. This study approves the traditional use of this plant and encourages further investigation on its bioactive compounds.
Opuntia dillenii is a medicinal plant with frequent usage in folk medicine to treat many illnesses. The present study aims to investigate the protective effect of Opuntia dillenii seed oil against gentamicin-induced nephrotoxicity in rats. The animals (rats) were randomly divided into three groups (i) the normal control group treated only with distilled water (10 mL/kg), (ii) the gentamicin group treated with distilled water (10 mL/kg) and received an intraperitoneal injection of gentamicin (80 mg/kg), and (iii) the group treated with the Opuntia dillenii seed oil (2 mL/kg) and also received an intraperitoneal injection of gentamicin (80 mg/kg). The rats received their following treatments for 14 consecutive days orally. Serum urea, creatinine, gamma-glutamyl transferase, albumin, and electrolyte levels were quantified as the markers of acute renal and liver failure. Besides, the kidney and liver relative weight, kidney malondialdehydes, and kidney histological analysis were determined. The results have shown that daily pretreatment with Opuntia dillenii seed oil (2 mL/kg) prevented severe alterations of biochemical parameters and disruptions of kidney tissue structures. In addition, the results of the present study showed for the first time that Opuntia dillenii seed oil reduced renal toxicity in gentamicin-induced nephrotoxicity in rats. Therefore, Opuntia dillenii seed oil may represent a new therapeutic avenue to preserve and protect renal function in gentamicin-treated patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
