This study recorded the use of medicinal plants in the rural communities from the municipality of Dolores Hidalgo, Guanajuato, Mexico. Data were obtained through open semi-structured interviews with local respondents (n=181), and medicinal plants were recorded and identified in herbariums. The Relative importance (RI) and Informant Consensus Factor (ICF) were calculated to analyze the survey data. In total, 68 plant species belonging to 33 families were reported. Asteraceae had the highest number of species, representing 14. The highest RI was accounted by Chamaemelum nobile (RI=2.0), followed by Thymus vulgaris (RI=1.83),and Moringa oleifera (RI= 1.60). The highest ICF was reported by diseases associated with the respiratory (ICF=0.80), digestive (ICF=0.75), and musculoskeletal systems including connective tissues (ICF= 0.71). Respondents have knowledge about medicinal plant use for primary health care and other chronic diseases. The information obtained here could be extrapolated to different rural areas in Mexico.

Concomitant use of allopathic medicine and herbal products for weight-loss among people with overweight or obesity from Central Mexico / Uso concomitante de medicina alopática y productos herbales para bajar de peso en personas con sobrepeso u obesidad del centro de México

This study evaluated the prevalence of concomitant use of herbal products for weight loss (HPWL) and allopathic medicine. Factors associated with the prevalence, adverse reactions, and the alteration of medication adherence with the concomitant use of HPWL alone and in combination with allopathic medicine, were assessed. The study was descriptive and cross-sectional using a questionnaire conducted among people with overweight or obesity (n=662) from five cities of Central Mexico. Adherence to medications was measured using the Morisky Medication Adherence Scale. The prevalence of adverse reactions induced by the concomitant use of HPWL, and allopathic medicine was 25.3%. The use of HPWL affected medication adherence by 68%. There is a high prevalence (45.2%) of concomitant use of HPWL and allopathic medicine in people with overweight or obesity in Central Mexico. The concomitant use of HPWL and allopathic medicine induces adverse reactions, mainly gastrointestinal, and thus, medication adherence is affected.

Este estudio evaluó la prevalencia del uso concomitante de productos a base de hierbas para bajar de peso (HPWL) y medicina alopática. Se evaluaron los factores asociados con la prevalencia, las reacciones adversas y la alteración de la adherencia a la medicación con el uso concomitante de HPWL solo y en combinación con medicina alopática. El estudio fue descriptivo y transversal mediante un cuestionario realizado entre personas con sobrepeso u obesidad (n = 662) de cinco ciudades del centro de México. La adherencia a los medicamentos se midió mediante la Escala de adherencia a la medicación de Morisky. La prevalencia de reacciones adversas inducidas por el uso concomitante de HPWL y medicina alopática fue del 25,3%. El uso de HPWL afectó la adherencia a la medicación en un 68%. Existe una alta prevalencia (45.2%) de uso concomitante de HPWL y medicina alopática en personas con sobrepeso u obesidad en el centro de México. El uso concomitante de HPWL y medicina alopática induce reacciones adversas, principalmente gastrointestinales, y por tanto, afecta la adherencia a la medicación.

Self-treatment and adverse reactions with herbal products for treating symptoms associated with anxiety and depression in adults from the central-western region of Mexico during the Covid-19 pandemic.

ETHNOPHARMACOLOGICAL RELEVANCE: There are plant species used in the Mexican traditional medicine for the empirical treatment of anxiety and depression. AIM OF THE STUDY: This work assessed the prevalence of self-medication with medicinal plants and the prevalence of the concomitant use of prescribed psychiatric drugs and medicinal plants for treating symptoms associated with anxiety and depression during the Covid-19 lockdown in Mexico. MATERIALS AND METHODS: The suspected adverse reactions associated with drug-herb interactions were assessed. The factors associated with self-medication, the concomitant use of herb-drug combinations, and the presence of adverse reactions due their combined use is also reported. The study was descriptive and cross-sectional using an online questionnaire conducted among population with symptoms associated with anxiety and depression (n = 2100) from seven states of central-western Mexico. RESULTS: The prevalence of the use of herbs (61.9%) and the concomitant use of drug-herb combinations (25.3%) were associated with being diagnosed with mental illness [OR:2.195 (1.655-2.912)] and the use of psychiatric medications [OR:307.994 (178.609-531.107)], respectively. The presence of adverse reactions (n = 104) by the concomitant use of drug-herb combinations was associated with being unemployed [p = 0.004, OR: 3.017 (1.404-6.486)]. CONCLUSION: Health professionals should be aware if their patients concomitantly use medicinal plants and psychiatric drugs. Public health campaigns should promote the possible adverse reactions that might produce the concomitant use of drug-herb combinations for mental illnesses.
