Resumo: Introducción: Las enfermedades de la piel ocupan el tercer lugar dentro de las 10 causas de morbilidad general en Ecuador y las prácticas de la medicina tradicional son las opciones terapéuticas más frecuentes en los sectores rurales. Objetivo: Identificar las plantas medicinales utilizadas para el tratamiento de enfermedades de la piel. Diseño: Estudio descriptivo, transversal. Lugar: Dos parroquias rurales del cantón Babahoyo -Pimocha y Febres-Cordero-, ubicadas al sur de la provincia de Los Ríos, Ecuador. Participantes: Personas responsables del cuidado de la familia, conformado por 198 mujeres (61,7%) y 123 hombres (38,3%), de edades entre 17 y 76 años. Intervenciones: Previo consentimiento informado, se realizaron observaciones directas, entrevistas y encuestas, en las cuales se utilizó el cuestionario U-PlanMed. Principales medidas de resultados: Especies de plantas y usos terapéuticos. Resultados: Se identificaron 10 especies de plantas y sus aplicaciones terapéuticas en enfermedades como acné, quemaduras, prurito, sarpullido, dermatitis, ulceraciones de la piel (llagas), manchas y cuidado de la piel. Conclusiones: El 100% de la población utilizó plantas medicinales para el tratamiento de afecciones de la piel, siendo las más usadas la Aloe vera (Sábila), Chamaemelum nobile (manzanilla), Melissa officinalis (toronjil) y Scoparia dulcis (teatina).

Título: Antibacterial, anti-swarming and anti-biofilm formation activities of Chamaemelum nobile against Pseudomonas aeruginosa

Resumo: AbstractINTRODUCTION:

Chamomile ( Chamaemelum nobile ) is widely used throughout the world, and has anti-inflammatory, deodorant, bacteriostatic, antimicrobial, carminative, sedative, antiseptic, anti-catarrhal, and spasmolytic properties. Because of the increasing incidence of drug-resistant bacteria, the development of natural antibacterial sources such as medical herbs for the treatment of infectious diseases is necessary. Extracts from different plant parts such as the leaves, flowers, fruit, and bark of Combretum albiflorum, Laurus nobilis , and Sonchus oleraceus were found to possess anti-quorum sensing (QS) activities. In this study, we evaluated the effect of C. nobile against Pseudomonas aeruginosa biofilm formation

METHODS:

The P. aeruginosa samples were isolated from patients with different types of infection, including wound infection, septicemia, and urinary tract infection. The flowers of C. nobile were dried and the extract was removed using a rotary device and then dissolved in dimethyl sulfoxide at pH 7.4. The microdilution method was used to evaluate the minimum inhibitory concentration (MIC) of this extract on P. aeruginosa , and biofilm inhibition was assayed.

RESULTS:

Eighty percent of the isolated samples (16/20) could form a biofilm, and most of these were isolated from wound infections. The biofilm inhibitory concentration of the C. nobile extract was 6.25-25mg/ml, whereas the MIC was 12.5-50mg/ml.

CONCLUSIONS:

The anti-QS property of C. nobile may play an important role in its antibacterial activity, thus offering an additional strategy in the fight against bacterial infections. However, molecular investigation is required ...
