Herbal infusions (HI) are a popular type of beverage known for their potential health benefits due to the extraction of phytochemicals and bioactive compounds. The Mediterranean Diet (MD) is a well-known dietary pattern with beneficial effects on health, and Psychological Resilience (PsyR) is a key indicator of mental health and human well-being. The aim of this cross-sectional study was to explore the relationship between HI and the MD, as well as their association with PsyR. The study included 398 healthy adults from Greece who participated voluntarily in an online research survey. The results indicated that 45.9% of participants consumed HI more than twice per week. There was a statistically significant association between the weekly consumption of HI and the Mediterranean Diet Adherence Screener (14-MEDAS), which identified HI consumption as a prognostic factor of high adherence to the MD. Additionally, HI consumption was significantly associated with PsyR. St John’s wort, green tea, and Greek mountain tea were associated with higher levels of PsyR. Greek mountain tea was also associated with a healthful and sustainable lifestyle. These findings suggest that HI are an integral part of the Mediterranean Diet, and their consumption is associated with PsyR. Promoting the consumption of HI such as Greek mountain tea and other herbs could be an effective way to promote healthy lifestyle behaviors and sustainable practices. Further randomized control trials are needed to confirm the results of this study. Full article

The stimulation of melanogenesis by novel natural products is desirable for cosmetic applications such as skin tanning, anti-greying, and clinical use for treating vitiligo and leukoderma disorders. Microphthalmia transcription factor (MITF) is a central transcription factor that controls the expression of tyrosinase, which is a key enzyme responsible for catalyzing the rate-limiting processes of melanin production. Tetrahydrocurcuminoids (THCr), which mostly consist of tetrahydrocurcumin (THC), are a colorless bioactive mixture derived from curcuminoids that are extracted from the Curcuma longa plant. THCr has been reported to exhibit superior properties, including antioxidant and anti-inflammatory effects. Our previous study reported the greater melanogenesis-stimulating effects of purified THC, compared to hexahydrocurcumin (HHC) or octahydrocurcumin (OHC). Curowhite™ (CW) is a proprietary extract that consists of 25% hydrogenated curcuminoids (mixture of THCr, hexahydrocurcuminoids, and octahydrocurcuminoids) encapsulated in a β-cyclodextrin (βCyD) excipient. The encapsulation of THCr in a suitable excipient, such as the widely popular cyclodextrins, helps to enhance the stability, solubility, and bioavailability of the THCr. CW is marketed as a nutraceutical with GRAS status and is safe when administered orally, as shown in vivo studies. However, the impact of CW on melanogenesis remains unexplored. Herein, the impact of CW on melanogenesis were investigated using B16F10 and MNT-1 cells. Our findings show that CW is markedly cytotoxic to B16F10 cells without affecting the cellular melanin content. However, in MNT-1 cells, CW significantly stimulated intracellular melanin content over the concentration range (20–60 µg/mL) with increased dendrite formation while being nontoxic to MNT-1 cells or HaCaT cells after a 5-day treatment. Examination of the effects of the excipient βCyD on cytotoxicity and melanogenesis confirmed that the excipient had no contribution to the biological impacts that were found to be exclusively attributable to the encapsulated mixture (THCr). The mechanisms of CW’s promelanogenic effects in MNT-1 cells were found to be related, at least in part, to an increase in tyrosinase and MITF protein levels, as CW did not alter tyrosinase activity in MNT-1 cells. Moreover, CW exhibited antioxidant activity as obtained through DPPH radical scavenging assay. Together, the findings of this pilot study indicate that CW might hold an exciting avenue as a pro-pigmenting nutraceutical for treating hypopigmentation disorders, the detailed mechanisms of which warrant further exploration. Moreover, future investigations are necessary to examine CW’s effects on melanogenesis in normal human melanocytes and in vivo studies. Full article

Plants with therapeutic potential are a rich resource for the inhabitants of a country, with Romania among them, having a diverse flora not only from plants but also from fungi. New trends in biopharmaceuticals are also addressed in studies related to topical administration, representing a great advantage; research has determined biological activities in vivo and in vitro. This study aimed to present the main active compounds from extracts of Lactarius piperatus, Centaurea cyanus, and Ribes rubrum. In vitro (DPPH scavenging activity and reducing power) and in vivo activities were determined. A survey of hydrating cosmetic products and the completion of a patch test (in vivo test) under dermatological control were realized to confirm the skin compatibility of the product in a panel of human subjects after a single application. The cosmetic product did not induce allergic reactions, erythema, irritation, or itching. This study showed that the extracts incorporated in the formulation of the face cream had a nutricosmetic effect. The research demonstrated a result of increasing skin elasticity and an anti-inflammatory effect following direct application to the skin of volunteers. The product offered in vitro/in vivo protection against the action of free radicals; it was effective in reducing the side effects of exposure to the action of blue light. Full article

This study evaluated the anti-inflammatory effects, the protection of gut barrier integrity, and the stimulation of phagocytosis in peripheral cells of a nutritional supplement based on a synergistic combination of yeast-based ingredients with a unique 1,3/1,6-glucan complex and a consortium of postbiotic Saccharomyces cerevisiae rich in selenium and zinc. The anti-inflammatory effect in caco-2 cells in the presence and absence of a pro-inflammatory challenge (tumour necrosis factor alpha [TNF-α]/interferon gamma [IFN-ɣ]) showed statistically significant reductions in IFN-ɣ induced protein-10 (IP-10), and monocyte chemoattractant protein-1 (MCP-1) levels vs. controls (p < 0.001). Disruption of the gut integrity in the presence or absence of Escherichia coli (ETEC H10407) showed transepithelial electrical resistance (TEER) values higher in the ABB C1^® group after 6 h of testing. Spontaneous build-up of the gut epithelium monolayer over 22 days was also greater in the ABB C1^® condition vs. a negative control. ABB C1^® showed a significantly higher capacity to stimulate phagocytosis as compared with controls of algae β-1,3-glucan and yeast β-1,3/1,6 glucan (p < 0.001). This study supports the mechanism of action by which ABB C1^® may improve the immune response and be useful to prevent infection and allergy in clinical practice. Full article

The various clinical approaches for treating allergy-related diseases have shown modest progress in low side effects and improved clinical outcomes. Therefore, finding alternative anti-allergic agents is crucial. The present study explored the anti-allergic effects of amber extract (fossilized tree resin) in RBL-2H3 mast cells stimulated with different allergens. In order to support the information on the inflammatory effect of the amber extract, NO production analysis on RAW 264.7 cells was conducted. β-Hexosaminidase release, an indicator of the efficacy of the amber extract in preventing mast cell activation and degranulation, reactive oxygen species (ROS) generation, and the effect of the amber extract on key cytokines production on RBL-2H3 cells, was evaluated. The results demonstrated that amber extract at concentrations up to 50 μg/mL had no cytotoxic effect on RAW 264.7 and RBL-2H3 cells. Amber extract inhibited NO production in RAW 264.7 cells. Treatment with amber extract significantly suppressed the release of β-hexosaminidase, especially at 50 μg/mL. Furthermore, amber extract suppressed the significantly increased ROS levels induced by allergen stimulation and allergy-associated cytokines. The results also suggested that amber extract exerts anti-allergic inflammatory effects by inhibiting the MAPK and NF-κB signaling pathways, resulting in decreased cytokines production. Thus, the amber extract is a promising anti-allergic agent. Full article

Research on nutraceuticals has focused on reducing the onset, progression, and significant consequences of diabetes mellitus. Arctium lappa Lam. is a great source of plant fibers and polyphenols that have anti-disease benefits, including those for diabetes mellitus. This study sought to determine the impact of Arctium lappa Lam. extracts and its associated lignans on diabetic hyperglycemia and dyslipidemia by conducting meta-analyses of the available research using diabetic rodents. English-language peer-reviewed articles were searched by PubMed and Embase up until 10 August 2022. Included were studies comparing the blood glucose and/or lipid levels of diabetic rodents given either extracts of Arctium lappa Lam. and its related lignans or vehicles. Blood glucose levels were reported in 16 studies involving 168 diabetic mice or rats treated with Arctium lappa Lam. and 168 diabetic controls. The pooled effect size was −1.42 [95% CI: −1.84 to −1.00] with significant heterogeneity. Type of diabetic model was found to be the prominent covariate that explained, at least partially, the heterogeneity. Moreover, diabetic rodents treated with Arctium lappa Lam. showed a notable improvement in their hypertriglyceridemia and hypercholesterolemia. Full article

Inflammation and cancer are diseases caused by genetic and environmental factors as well as altered microbiota. Diet plays a role, with leguminous such as beans (Phaseolus vulgaris, Vicia faba), chickpeas (Cicer arietinum), lentils (Lens culinaris), peas (Pisum sativum) and soybeans (Glycine max), known to prevent such diseases. Processing of food leguminous yields aqueous side streams. These products are nothing short of water extracts of leguminous, containing albumin, globulin, saponins, and oligosaccharides. This review analysed the most recent findings on the anticancer activities of legume-soluble nutrients. Albumin from chickpeas and peas inhibits the pro-inflammatory mediator interleukins, while soy Bowman–Birk Inhibitor inhibits serine proteases. The peptide vicilin activates peroxisome proliferator-activated receptor, mediating triglyceride metabolism. Soyasaponins promote apoptosis of cancer cells by activating caspases and by enhancing the concentration of intracellular calcium. Soyasapogenol regulates specific protein pathways, leading to apoptosis. Oligosaccharides such as raffinose and stachyose promote the synthesis of short chain fatty acids, balancing the intestinal microbiota, as result of their prebiotic activity. Verbascoside also modulate signalling pathways, leading to apoptosis. In closing, water extracts of leguminous have the potential to be efficient anticancer ingredients, by means of numerous mechanisms based on the raw material and the process. Full article
