Since ancient times, plants have been used to preserve food, or for their health properties. Essential oils are complex mixtures of volatile compounds that are obtained from botanical material, specifically from aromatic plants. Lamiaceae is one of the most important families in the production of essential oils, as it has both antioxidant and antimicrobial properties. The essential oils of Mentha (the Lamiaceae family) have been extensively studied for their biological actions. In this review, we report the antioxidant, antifungal, antibiofilm, and cytotoxic properties of Mentha spp.

BACKGROUND: Our research was focused on the analysis of the antimicrobial and antibiofilm power of two commonly used oral toothpastes containing different concentrations of fluorine. These toothpastes were tested in vitro on deciduous teeth. METHODS: Culture of S. mutans was inoculated in 1 mL of sterile phosphate buffered saline (PBS) with a 5% of toothpaste concentration with 500ppm e1400ppm of fluorine. The ability of the bacteria to form colonies was measured by counting the number of Colony Forming Units (CFU).

Bacterial biofilm plays a pivotal role in chronic Staphylococcus aureus (S. aureus) infection and

The society has become increasingly interested in using natural products over chemicals for cleaning activities. In this study, the cleaning potential of formulations embedded in a hydrogel matrix and composed respectively of essential oils (EOs) of Origanum vulgare, Thymus vulgaris, and Calamintha nepeta, and their respective main active components (EO-ACs), viz., Carvacrol, Thymol, and Pulegone, on a phototropic biofilm growing on granite was investigated.
