The status of parsley as a well-known folk medicine noted for its nutritional and medicinal properties prompted the exploration of its potential as a functional food and natural remedy. The paper aims to investigate the potential of parsley to enhance muscle function and alleviate psoriasiform dermatitis, eventually establishing it as a natural, well-tolerated alternative with specific benefits for both muscles and skin. This study examines the tolerability of parsley in a cohort of 937 participants by assessing immunoglobulin G (IgG) reactions. The findings reveal high tolerability, as 96.26% of participants experienced no adverse effects. Among the 902 individuals lacking hypersensitivity, 37.02% reported muscle cramps, with a notable 15.02% reduction observed in the subgroup consuming parsley juice. In the subset of 32 subjects with dermatitis, the application of parsley extract ointment led to a significant decrease in dermatological parameters (redness, thickness, scaling). While the control group exhibited improvements, statistical significance was not observed. Notably, four categories of affected area reduction were identified, with scaling demonstrating the most pronounced impact. The results propose that parsley holds promise for favorable tolerability, contributing to the alleviation of muscle cramps and presenting an effective alternative in dermatitis treatment. Nonetheless, sustained validation through long-term studies is imperative to substantiate these preliminary findings.

Functional foods play a crucial role in contemporary dietary strategies. This study investigates the incorporation of oregano oil, a bioactive extract that is known for its antimicrobial and antioxidant properties, into gelatin-based gummy jellies to develop functional food products with controlled release properties. The jellies were evaluated for mass uniformity, swelling index, disintegration time, and tensile strength under simulated oral and gastric conditions. The results showed that oregano oil significantly reduced the swelling index (e.g., 128.76 ± 0.67% at pH 5) and prolonged the disintegration time (e.g., 6–18 min across pH environments), highlighting its potential for controlled release. The mechanical strength remained stable (5.2 ± 0.3 N), ensuring structural integrity. These findings suggest that oregano-oil-enriched gummy jellies offer health benefits, although further studies are needed to explore their long-term stability and bioavailability.

(1) Background: This systematic review explores the bioactive properties of Punica granatum (pomegranate) and its potential applications in the prevention and treatment of gingivitis, periodontitis, and other oral diseases. (2) Methods: A comprehensive literature search was conducted using PubMed and Google Scholar, focusing on pomegranate and oral diseases. Inclusion criteria included studies evaluating the effects of pomegranate on oral health, while exclusion criteria eliminated non-peer-reviewed and non-English articles. This review aims to assess the efficacy of pomegranate extracts as a natural alternative to synthetic pharmaceuticals in oral health care. A structured search strategy included key terms such as “pomegranate”, “oral health”, “gingivitis”, and “periodontitis”. A total of 125 relevant references were reviewed to identify the most pertinent findings. (3) Results: The results indicate that pomegranate extracts have demonstrated efficacy in reducing plaque, inhibiting harmful oral microorganisms, and promoting overall oral health. Furthermore, clinical studies highlight the potential of pomegranate-based products, such as mouthwashes and gels, as viable alternatives to conventional pharmaceuticals, particularly in resource-limited settings. However, the review also notes the need for further research, particularly in the form of clinical trials, to establish optimal formulations and long-term safety. (4) Conclusions: Pomegranate presents a promising, natural solution for preventing and treating gingivitis and periodontitis. Further studies should focus on long-term effects and clinical efficacy.

Background: Human cutaneous reactivity exhibits marked inter-individual variability, yet the contribution of constitutional pigmentation traits to short-term skin responses remains incompletely characterized. Fitzpatrick skin phototype reflects stable differences in pigmentation-related traits and may therefore act as a phenotypic modifier of early cutaneous reactivity following topical exposure. Methods: In this controlled human study, 239 healthy volunteers were stratified by Fitzpatrick skin phototype into three groups: I–II (n = 138), III (n = 72), and IV–V (n = 29). A standardized emulgel-based topical provocation model was applied under occlusion to the volar forearm, and cutaneous responses were assessed at 20 min (Test A), 24 h (Test B), and 96 h (Test C) using standardized visual scoring. Group comparisons, multivariable linear regression models adjusted for age, sex, country of origin, and experimental lot, and stratified analyses by country of origin, were performed. Results: Early and short-term cutaneous responses differed significantly across phototype groups. Participants with phototypes I–II exhibited higher response scores at both 20 min and 24 h compared with phototype III (p < 0.001). In adjusted models, phototype III remained independently associated with significantly lower reactivity relative to phototypes I–II at 20 min (β = −1.61, p < 0.001) and 24 h (β = −0.98, p < 0.001). Responses among phototypes IV–V were minimal to absent; however, this subgroup was underrepresented, and findings for IV–V are descriptive. Age was a significant positive predictor of response intensity, whereas sex showed no independent association. No persistent reactions were observed at 96 h in any phototype group. Stratified analyses confirmed that the reduced reactivity associated with phototype III was independent of country of origin. Conclusions: Fitzpatrick skin phototype is independently associated with early and short-term cutaneous reactivity following standardized topical provocation in humans. Lighter phototypes (I–II) demonstrate increased susceptibility to transient inflammatory responses, whereas phototype III shows markedly reduced reactivity. These findings support the role of skin phototype as a constitutional modifier of short-term cutaneous responses and highlight the importance of considering pigmentation-related phenotypes in the design and interpretation of dermatological testing, cosmetic tolerability studies, and safety assessments of topical formulations.

Background: Salivary pH plays a critical role in oral health by influencing enamel demineralization, buffering capacity, and the ecology of oral microbiota. Essential oils such as Origanum vulgare (oregano) possess well-documented antimicrobial properties that may reduce acidogenic bacterial activity. However, the effects of edible delivery systems like jellies on salivary pH modulation and their potential interactions with hormonal states remain poorly understood. Methods: This study evaluated the in vitro antimicrobial activity of an oregano-oil-based jelly formulation against standard bacterial (Staphylococcus aureus, Streptococcus pyogenes, and Escherichia coli) and fungal (Candida albicans) strains using the Kirby–Bauer disc diffusion method. Additionally, a human trial (n = 91) measured salivary pH before and after administration of the oregano-oil jelly. Participants were characterized by age, smoking status, menopausal status, and presence of menstruation. Multiple linear regression was used to identify predictors of final salivary pH. Results: The oregano-oil jelly demonstrated strong in vitro antimicrobial activity, with inhibition zones up to 8 mm for E. coli and C. albicans. In vivo, mean unstimulated salivary pH increased from 6.94 to 7.07 overall, indicating a mild alkalinizing effect. However, menstruating participants showed a significant decrease in final pH (from 7.03 to 6.78). Multiple regression identified menstruation as a significant negative predictor (β = −0.377, p < 0.001) and initial pH as a positive predictor (β = +0.275, p = 0.002). Menopausal status was not a significant predictor, likely due to the small sample size. Conclusions: Oregano-oil jellies may represent a promising natural approach to support oral health by increasing salivary pH and providing strong antimicrobial activity. However, physiological states such as menstruation can significantly modulate this response, underscoring the importance of personalized or phase-aware oral care strategies. Further studies with larger, diverse cohorts and controlled hormonal assessments are needed to validate these findings and optimize product formulations.

Background/Objectives: Antimicrobial resistance has renewed interest in plant extracts, essential oils and honey as topical adjuvants, yet antimicrobial potency, host-tissue safety and formulation performance are usually reported in separate bodies of literature, and the material tested is often characterized only superficially. This structured narrative review aimed to integrate these dimensions into a single decision-oriented pathway. Methods: The Web of Science Core Collection was searched using seventeen predefined strings across fourteen thematic domains, restricted to English-language articles and reviews from 2021 to 2026, with supplementary PubMed/MEDLINE searches, hand-searching, and normative documents from the issuing organizations. Results: The framework comprises seven decision domains: pre-analytical standardization of each matrix class; antibacterial and antifungal testing with matrix-specific controls; biofilm endpoints named according to what they measure; strain selection tiered from reference to clinical and resistant isolates; host safety from monolayer cytotoxicity to reconstructed human epidermis; selectivity, expressed per microorganism and extended to the resident cutaneous microbiota; and formulation performance, with permeation interpreted against a retention rather than a maximization target. Resistance under sub-inhibitory exposure forms an advanced stage. Conclusions: Progression is governed by proposed Go, Conditional Go and No-Go criteria, supported by a matrix-specific control table and a minimum reporting checklist. The framework has not been prospectively validated, and no universal selectivity threshold is proposed.
