The Effect of Hydroalcoholic Extracts of Medicinal Plants on Fungi Isolated From Toilet and Nursery Surfaces in a Daycare Center: An In Vitro Study.

Background Brazil has the most extensive plant genetic biodiversity in the world. Knowledge regarding the therapeutic properties of medicinal plants obtained through popular medicine has been accrued over centuries. Such empirical knowledge often symbolizes the only therapeutic resource for various ethnic communities and groups. This study aimed to evaluate the efficacy of hydroalcoholic extracts of medicinal plants in controlling isolated fungi found in bathrooms and nurseries of a daycare center in the northwestern region of São Paulo state. Methodology This is an in vitro study carried out in the microbiology laboratory. The analyzed fungi were , spp., , , and . These fungi were exposed to the hydroalcoholic extracts of rosemary, citronella, rue, neem, and lemon. Results Rue extract was more effective against at a concentration of 12.5%. Citronella was effective against and at a concentration of 6.25%. Lemon was effective against spp. at a concentration of 6.25%. Conclusions The hydroalcoholic extracts showed antifungal activity. The in vitro evaluation of medicinal plants showed that the extracts of rue, citronella, and lemon showed a fungicide effect.
