Antimicrobial Effect of Ginger, Garlic, Honey, and Lemon Extracts on Streptococcus mutans

ABSTRACTAimThe aim of this study was to evaluate the effect of lemon, ginger, garlic, and honey extracts onStreptococcus mutans.Materials and methodsCommercially obtained honey, ginger, garlic, and lemon were included in the study to evaluate its efficacy in isolation and in combination againstS. mutans. The efficacies of extracts were tested using well diffusion method, and its effect was evaluated by measuring the zone of inhibition around the well. Antimicrobial activity of the extracts was carried out individually and compared considering triplicates of all the extracts.ResultsWhen individual comparison of the extracts was made, garlic showed greatest antimicrobial activity with a mean zone of inhibition (34.9 ± 0.58 mm) and honey showed least antimicrobial activity (0.5 ± 0.6 mm). When combinations of extracts were tested againstS. mutans, lemon and garlic combination showed the greatest zone of inhibition (27.6 ± 0.43 mm) compared with other combinations, and ginger + lemon combinations showed the least zone of inhibition (12.6 ± 0.43 mm).ConclusionThis study concluded that garlic showed a greatest antimicrobial effect againstS. mutanswhen compared with preparations individually and garlic and lemon showed greatest zone of inhibition in combination than other preparations.Clinical significanceAntibiotics and other chemical agents are mainly used to treat the common dental infections. However, due to the excessive use, it can result in antibiotic resistance. Hence, herbal medicines with medicinal values should be replaced with conventional methods.How to cite this articleMathai K, Anand S, Aravind A, Dinatius P, Krishnan AV, Mathai M.
