The repellent activity and mechanism of estragole, a constituent of Fraction 1, were further investigated. The results indicated that estragole exerted dose- and time-dependent repellent effects. Moreover, similar to the commercial repellent DEET, estragole significantly upregulated the expression of the odorant-binding protein TcOBPC11 and chemosensory protein TcCSP9.

Twenty-two studies met the inclusion criteria, and 18 reported antihyperglycemic effects of the plant, either alone or as an adjunct to insulin. Additional benefits included improvements in lipid and antioxidant profiles. The fruit was used in 16 studies, with the peel being the most frequent and effective part (11 studies), likely related to its high content of pectin, phenolics, and flavonoids. Proposed mechanisms include delayed intestinal glucose absorption, stimulation of insulin secretion, partial regeneration of pancreatic β-cells, activation of the PI3K/AKT and AMPK pathways, and antioxidant and hypolipidemic actions.

Conventional treatments, including antibiotics and mechanical plaque control, have limitations due to antimicrobial resistance and adverse effects. Polyphenols, a diverse class of bioactive phytochemicals, exhibit promising antimicrobial, anti-inflammatory, and antioxidant properties that can be leveraged for oral health management. This review explores the therapeutic potential of polyphenols in targeting key pathogenic mechanisms associated with oral diseases. Polyphenols exert antimicrobial effects by disrupting bacterial membrane integrity, inhibiting biofilm formation, and interfering with quorum sensing pathways of oral pathogens such as Streptococcus mutans and Porphyromonas gingivalis. Additionally, their anti-inflammatory properties involve modulation of NF-κB signaling, suppression of pro-inflammatory cytokines (IL-1β, TNF-α, COX-2), and attenuation of oxidative stress through upregulation of endogenous antioxidants. Polyphenols also influence oral microbiota composition, promoting a balanced microbial ecosystem that supports oral health. However, challenges such as poor bioavailability, stability, and interindividual variability in response remain major hurdles. Advances in nanotechnology and controlled-release systems offer promising strategies to enhance polyphenol efficacy in dental applications.
