“…Similar results were reported for water extracts of rosemary (Rosmarinus officinalis L.) against S. sobrinus (MIC of 16 mg/mL). 9 In the present study, it was demonstrated that the RM extract, as compared with the GM extract, exhibited a greater inhibitory effect on GTF activity, despite having lower phenolic and flavonoid contents. The kinetic results indicated that the RM extract competitively inhibited GTF activity in a concentration-dependent manner, with an IC 50 value of 10 mg/mL, whereas a drastic decrease in GTF activity (~80% that of the control) was observed in the presence of 16 mg/mL.…”

“…The total phenolic content was determined using the Folin-Ciocalteu reagent as described by Tsai et al 9 and the results were expressed as chlorogenic acid equivalents (CAE). The total flavonoid contents of the extracts were determined using a colorimetric assay.…”

“…2,5,6 The inhibition of GTFs both in solution and adsorbed to the pellicle of the tooth surface is one of the strategies used to prevent dental caries and other plaquerelated diseases. Some studies have demonstrated an inhibitory activity of natural herbs such as oolong tea, 7 Chinese black tea 8 and rosemary extract 9 on GTF. Yerba mate (Ilex paraguariensis) is a plant native to the subtropical region of South America.…”

Objective: To evaluate the effectiveness of herbal medicaments such as ginger, rosemary and honey on remineralization of initial enamel lesion. Methods: Demineralized human enamel specimens were measured for baseline surface microhardness and fluorescence methods. Ten specimens in each of four groups were used in this in vitro recycling study with the following treatments which applied three times a day: 1) sodium fluoride toothpaste (Ipana, Procter & Gamble, Turkey), 2) gingerhoney (Arifoglu Herbals, Anzer Honey, Turkey), 3) ginger-honey-chocolate (Bind Chocolate, Turkey), 4) rosemary oil (Arifoglu Herbals, Turkey). Treatment regimens of demineralization and remineralization cycle were applied for 21 days. The post-treatment data were obtained by measurements of surface microhardness and fluorescence methods. Data were statistically analyzed by ANOVA test with Tukey's honest significant difference test. Results: Enhanced remineralization was observed with several of the treatment systems including ginger + honey and rosemary. Significant differences between treatments were observed by microhardness and FluoreCam fluorescence assesment, compared to the positive control group (NaF dentifrice). Significantly, greater remineralization was observed with the honey + ginger treatment regimen. No significant differences between groups were observed using the fluorescence assessment method, quantitative lightinduced fluorescence. Conclusions: Herbals (ginger, honey and rosemary) have enhanced remineralization of initial enamel lesion.

“…Several microorganisms are affected by extracts of rosemary ( Table 3; [121]). Crude aqueous and methanolic extracts of rosemary are able to inhibit growth (MIC of 16 and 4 mg/mL, respectively) of Streptococcus sobrinus and the synthesis of the water-insoluble glucan produced by this bacterium during dental plaque formation [122]. The diterpenes extracted from rosemary leaves (carnosol, carnosic acid and rosmadial) affect lipid polymorphism and fluidity of phospholipid membranes [65].…”

This paper reviews the benefits of the Mediterranean diet and methods developed for food processing and preservation during the time of the ancient empires. In Antiquity, trees and herbs were harvested for culinary and medicinal purposes, and from the everyday handling of products and keen observation, a great body of wisdom was derived by philosophers and physicians. With modern day techniques, the suspected properties of compounds have been investigated and the beneficial properties tested. From these studies it is apparent that olive oil, herbs, essential oils and metals, when used with the backing of scientific knowledge can improve human health and the standards of living while respecting the environment. Nowadays, proliferation of disinfectants and antimicrobial agents in domestic, industrial and medical environments has contributed to the appearance of resistant microbial strains and of new pathogens. Since regulators have restricted the use and concentrations of many preservatives, sanitizers, and antimicrobial agents, the food industry is facing a problem to extend the shelf-life of products, and to keep the manufacturing environment clean. The application of natural compounds and simple techniques developed by ancient Mediterranean civilizations may prove as useful as more modern synthetic substances, thus avoiding potential threats to human health and the environment.
