Abstract

I examined the antimicrobial efficacy of both Neurolaena lobata and Ageratum conyzoides found in Monteverde. These two plants are in the Asteraceae family, and can be used to treat gastrointestinal discomfort. Both have been proven to be effective antimicrobials against E. coli and S. aureus. I tested each plant on E. coli and S. aureus using a Kirby-Bauer assay and an agar well diffusion method. For Neurolaena lobata plated on S. aureus, solutions of young leaves exhibited significantly higher inhibition zones than solutions of both old leaves and control disks. I also gathered local knowledge on medicinal plants using a survey method, in which 31 participants responded to questions regarding their use and knowledge of medicinal plants. Twenty nine out of 31 participants use medicinal plants in some way, and at least 12 different families of medicinal plants are used in Monteverde. Estudié la eficacia antimicrobiana de Neurolaena lobata y Agertum conyzoides en Monteverde. Estas dos Asteraceae pueden utilizarse para tratar malestares gastrointestinales. Ambas especies han demostrado su eficacia contra E. coli y S. aureus. Estudié las bacterias E. coli y S. aureus, utilizando un mètodo de Kirby-Bauer y un método de difusión de pozos de agar. Para soluciones de Neurolaena lobata sobre S. aureus, las soluciones de hojas jóvenes exhibieron zonas de inhibición significativamente mayores que las soluciones de hojas viejas y discos de control. No encontré ninguna otra inhibición significativa. Compilé además conocimientos locales sobre plantas medicinales mediante una encuesta, en la que 31 participantes respondieron a varias preguntas sobre su uso y conocimiento de plantas medicinales. Veintinueve de los 31 participantes usan plantas medicinales, y por lo menos 12 familias de plantas medicinales se utilizan en Monteverde.
