In order to identify the medicinal and aromatic plants most requested for the treatment of the most common oral pathology, an ethnobotanical survey was carried out in the economic capital Casablanca, Morocco. The data basis was obtained draw selected traditional herbalists based on the semi-structured questionnaire. Quantitative indices such as use value (UV), family UV (FUV), fidelity level and informant consensus factor (ICF) were intended to evaluate the importance of plant species. A total of 46 plants species belonging to 22 families that were used. Juglandaceae family showed the highest significance (FUV = 0.75). We identified 40 species used for gum disease (gingivitis, periodontal abscess), 15 for dental pain (toothache, tooth sensitivity), 14 for halitosis, 12 for oral ulcers (aphtous, mouth ulcers and herpes), 3 for dental stain (teeth cleaning, sparkling and bleaching) and only 2 for tooth decay. The used plants are mainly prepared as decoction (80.4%). Syzygium aromaticum (UV = 0.94) was the specie most commonly prescribed by local herbalists. The higher ICF (0.75) was registered for the use gum disease.Graphical Abstract Electronic supplementary materialThe online version of this article (10.1007/s13659-018-0194-6) contains supplementary material, which is available to authorized users.

BACKGROUND: The disturbance of students’ biological and academic rhythms induced by the Coronavirus generated considerable challenges that had an influence on their psychological well-being. This study aims to highlight the daily rhythm desynchronization and examine the mental health of Moroccan students who were impacted, notably females, in the context of the COVID-19 pandemic. METHODS AND MATERIAL: A cross-sectional online survey was conducted in May 2020 at ten Moroccan faculties including 312 students with an average age of 22 ± 1.70 years old, processed according to a random sampling. A Daily Activities Biorhythm Questionnaire was used to assess the students’ daily activities time use and duration, while the PTSD Symptom Scale, Hamilton Scale, Worry Domains Questionnaire, and Visual Analog Mood State Scale were used to assess their mental health. A statistical analysis used both Chi-square and t test to evaluate the relationship between females and males as two independent groups to the studied variables. RESULTS: Based on individual gender differences, a significant disruption emerged in the daily time use and duration of activities during home confinement. Besides, females were more likely to experience psychological issues notably anxiety (2.04 ± 0.49), physical tiredness (2.11 ± 0.39), sadness (p <.05), and posttraumatic stress disorder (p <.01). In contrast, there is a strong correlation between males’ concern of declining employment (p <.05) and their worry of declining family budgets (2.10 ± 1.39). CONCLUSIONS: As an emerging behavior for a new risk factor, the daily activities rhythm of Moroccan university students have been altered and mental health difficulties have appeared due to the quarantine isolation. This might influence their overall academic performance and psychological balance. In this instance, psychological assistance is highly recommended.
