Context: Essential oils are prevalent in many medicinal plants used for oral hygiene and treatment of diseases.
Objective: Medicinal plant species were extracted to determine the essential oil content. Those producing sufficient oil were screened for activity against Staphylococcus aureus, Escherichia coli, Streptococcus mutans, Lactobacillus acidophilus, and Candida albicans.
Materials And Methods: Plant samples were collected, frozen, and essential oils were extracted by steam distillation. Minimum inhibitory concentrations (MIC) were determined using a tube dilution assay for those species yielding sufficient oil.
Results: Fifty-nine of the 141 plant species produced sufficient oil for collection and 12 species not previously reported to produce essential oils were identified. Essential oil extracts from 32 species exhibited activity against one or more microbes. Oils from eight species were highly inhibitory to S. mutans, four species were highly inhibitory to C. albicans, and 19 species yielded MIC values less than the reference drugs.
Discussion: RESULTS suggest that 11 species were highly inhibitory to the microbes tested and merit further investigation. Oils from Cinnamomum zeylanicum Blume (Lauraceae), Citrus aurantiifolia (Christm.) Swingle (Rutaceae), Lippia graveolens Kunth (Verbenaceae), and Origanum vulgare L. (Lamiaceae) yielded highly significant or moderate activity against all microbes and have potential as antimicrobial agents.
Conclusion: Teas prepared by decoction or infusion are known methods for extracting essential oils. Oils from 11 species were highly active against the microbes tested and merit investigation as to their potential for addressing health-related issues and in oral hygiene.

The urgent need to address the growing problem of antimicrobial resistance in multidrug-resistant bacteria requires the development of pioneering approaches to treatment. The present study aims to evaluate the antimicrobial potential of the essential oils (EOs) of Moringa oleifera (moringa), Cinnamomum verum (cinnamon), and Nigella sativa (black seed) and the synergistic effect of the mixture of these oils against Staphylococcus aureus MCC 1351. Statistical modeling revealed cinnamon oil had the highest individual antimicrobial potency, followed by black seed oil.

Concerns over malnutrition, synthetic additives and post-harvest waste highlight the need for innovation in food technology, turning towards underutilized crops. Plant-based beverages offer sustainable dietary alternatives and the increasing demand for such products makes the exploration of native crops particularly relevant. This study focuses on the development of a beverage derived from the native South American fruit kurugua (Sicana odorifera), combined with chia oil (Salvia hispanica L.

Unlabelled: is an acid-fast, aerobic, non-motile, and biofilm-forming bacterium. The increasing prevalence of mycobacterial infections makes it necessary to find new methods to combat the resistance of bacteria to conventional antibiotics. is an emerging pathogen that is intrinsically drug resistant due to several factors, including an impermeable cell envelope, drug efflux pumps, target-modifying enzymes, and the ability to form thick, robust biofilms.

Bone fractures are a leading cause of morbidity and healthcare expenditure globally. The complex healing process involves inflammation, cartilage formation, mineralization, and bone remodeling. Current treatments like immobilization, surgery, and bone grafting, though effective, pose significant challenges, such as prolonged recovery and high costs.

Background: Amorpha fruticosa was used for treating burn, ambustion, carbuncle, and eczema in the traditional Chinese medicine. Although more and more attention has been paid to its biological activity recently, the antitumor activities of the essential oils (EOs) extracted from its leaves (AFLEO) and flowers (AFFEO), and their molecular mechanisms have never been reported up to now. The objective of present study was to examine the chemical compositions of AFLEO and AFFEO, then investigate the effects and pharmacological mechanism of EOs against hepatocellular carcinoma (HCC).
