The present study aims to evaluation the antimicrobial effects of four herbal extracts in Streptococcus. mutants. These plants including Rhuscoriaria, Cinnamomum zelanicum, zingiber officinale, Camellia sinensis. Detection of antimicrobial activities of four methanolic herbal plants performed using agar diffusion method. After 24h of incubation the diameters of halos indicative of lack of growth in each well. The zone diameters around each disc were compared with chlorhexidine which is used as positive control. The study indicates methanolic concentration at (20%) have good potential activity on inhibition growth in Streptococcus mutants for C. zelanicum, Rcoriaria, Z. officinale, C. sinensis. (20.33, 17, 9.3, 8.2) respectively.
