Objective: The aim of this study was to evaluate the antibacterial effect of the methanolic extracts of Uncaria tomentosa (Cat´s Claw) againts Staphylococcus aureus (ATCC® 25923™) y Fusobacterium nucleatun (ATCC® 25586™). Material and Methods: The study was of experimental type in vitro. For the antibacterial activity the diffusion method was used in agar and to determine the minimum inhibitory concentration (MIC), the broth dilution method was used in Brain Heart Broth infusion medium (BHI). While the evaluation of the cytotoxic effect of the extract was evaluated by the colorimeter assay of 3-(4,5-dimethythiazol-2-yl)-2,5- diphenyltetrazolium bromide (MTT) using the Madin Darby Canine Kidney cell line (MDCK). Results: There is an antibacterial effect of the methanolic extract of Uncaria Tomentosa against Staphylococcus aureus, where inhibition halo of 31.3 ± 2.66 mm were observed. Clorhexidine 0.12% was used as a positive control with superior results of 59.1 mm ± 3.6 mm. On the other hand, there was not antibacterial effect against the Fusobacterium nucleatum strains. Then, the MIC of the extract was 0.0016 mg/ml against Staphylococcus aureus. The cell viability of the extract is maintained at high values (16,000 mg/ml), no cytotoxic effect was found. Conclusion: With the antimicrobial activity of the extract of Uncaria tomentosa, it´s suggested to continue with more research that contributes to scientific knowledge and from this, new antibacterial drugs can be developed in different presentations and thus face the different problems in oral health.
