Abstract

Background/Objectives: Oral health is a complex concept involving physical, psychological, emotional, and social components. A key factor in maintaining oral tissue integrity is redox balance, which is disrupted by oxidative stress (OS) through an imbalance between reactive oxygen species (ROS) and antioxidant defenses. This study examines the contribution of endogenous and exogenous sources to OS and explores the therapeutic potential of medicinal plants from the Asteraceae and Lamiaceae families in restoring redox homeostasis and improving oral health. Methods: A literature review was conducted, analyzing the role of OS in oral diseases and the antioxidant mechanisms of selected Asteraceae species. Special attention was given to their phytochemical contents—polyphenols, flavonoids, and essential oils—and their biological relevance to oral health. Results: OS plays a critical role in the onset and progression of oral conditions such as caries, periodontitis, gingivitis, aphthous ulcers, abscesses, precancerous lesions, and oral cancers. ROS and reactive nitrogen species (RNS) cause inflammation, tissue breakdown, and salivary gland dysfunction. Asteraceae plants like Matricaria chamomilla, Calendula officinalis, Cichorium intybus, Taraxacum officinale, Arctium lappa, Achillea millefolium, and Solidago virgaurea demonstrate notable antioxidant, anti-inflammatory, and antimicrobial properties that help counteract OS and support oral homeostasis. Conclusions: Asteraceae and Lamiaceae species show high therapeutic potential in addressing OS-related oral disorders. Their bioactive compounds aid in restoring redox balance and protecting oral tissues. These findings support the integration of phytotherapeutic agents into oral healthcare and call for further clinical validation of plant-based strategies for disease prevention and management.

  • Berberine reaches high local concentrations in the mouth before absorption and, being broadly antibacterial, can act on the oral microbial community.

    “Berberine reaches high local concentrations there before absorption and, being broadly antibacterial, can act on that community [107].”

    From Berberine-Drug Interactions: Mechanisms, Clinical Relevance and Risk Stratification-A Narrative Review (2026) · cites this paper as [107]

    Section 7.1.7 reports that berberine has antibacterial activity against two oral bacteria involved in periodontal disease, supporting its potential to act on members of the oral microbial community. It does not say berberine reaches high concentrations in the mouth before absorption or establish broad antibacterial activity across that community. No page number is provided in our copy. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • The oral compartment, where berberine reaches its highest concentrations of all, is unexamined and belongs in the same research program.

    “The oral compartment, where berberine reaches its highest concentrations of all, is unexamined and belongs in the same program [103,104,105,106,107,108].”

    From Berberine-Drug Interactions: Mechanisms, Clinical Relevance and Risk Stratification-A Narrative Review (2026) · cites this paper as [107]

    Section 9 (Future Research Directions; page unavailable) calls for further study of plant-derived compounds in oral health, supporting the general proposal to include the oral compartment in further research. But Section 7.1.7 already discusses berberine’s activity against oral bacteria, so the paper does not establish that this area is unexamined. It also gives no comparison showing that berberine reaches its highest concentrations in the mouth. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • No study has yet measured the disposition of a co-administered drug before and after berberine while characterizing the microbiota in the same subjects, which is what would move Axis 4 from candidate to demonstrated.

    “No study has yet measured the disposition of a co-administered drug before and after berberine while characterizing the microbiota in the same subjects, which is what would move Axis 4 from candidate to demonstrated.”

    From Berberine-Drug Interactions: Mechanisms, Clinical Relevance and Risk Stratification-A Narrative Review (2026) · cites this paper as [107]

    Section 7.1.7 discusses berberine’s antibacterial activity in the oral cavity, while Section 9 proposes research on medicinal plants and the oral microbiota. Neither addresses studies measuring a co-administered drug’s disposition before and after berberine while characterizing microbiota in the same subjects; searches for that study design and for berberine drug interactions found no relevant passage. Page numbers were not available in our copy. (LLM, conf=0.77)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
