The clinical studies proved the antimicrobial synergistic effect of probiotic bacteria and medicinal plants. In addition, this synergic effect can help to maintain food and prevent food corruption. There are plenty of pharmaceutical-probiotic products in the world and offering the same products in Iran is necessary. As Iran is the origin of variant medicinal plants that are used in Iranian conventional medicine, in this review, the synergistic effects of each one alone and with each other evaluated. The proposed mechanisms demonstrated that the oil essence part of plants and bacteriocins in probiotic bacteria, played the main synergistic role. Also, in this study, the synergistic effects of Iranian medicinal plants and probiotic bacteria assessed. It showed that some medicinal plants and probiotic bacteria would be able to have an adequate synergistic effect. Hence, using them in food and hygiene industries could reduce microbial contamination and improve society health.

In recent years, application of medicinal plants increase in the treatment of infections rather than antimicrobial drugs. The aim of this study was to compare the effects of silver nanoparticles and alcoholic extract of Amaranthus retroflexus on some pathogenic bacteria. The alcoholic extract of this plant was prepared and the effect of concentrations of 50 to 400 mg/ml of this extract and concentrations of 10 to 80 mg/ml of silver nanoparticles by well diffusion method on S. aureus, B. cereus, E coli and P aeruginosa were evaluated. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined on bacteria by dilution method. The results showed that the inhibition effect of Amaranthus retroflexus on gram-positive bacteria is more than gram negative bacteria while the inhibitory effect of silver nanoparticles on gram-negative bacteria is more than gram-positive bacteria. The results of this study showed that the alcoholic extract of Amaranthus retroflexus had an antibacterial properties that can be considered as an adjunct to further studies for in vivo conditions and replacement with common chemical agents in the treatment of infections.
