Goji berry leaves have stronger anti-colitis effects than mulberry leaves, ameliorating tissue damage and better regulating inflammatory responses and gut microbiota.
2023 Food & Function Goji berry leaf exerts a comparable effect against colitis and microbiota dysbiosis to its fruit in dextran-sulfate-sodium-treated mice Yu C, Chen Y, Ahmadi S, Wu D, Wu J, Ding T, et al.
Experimental Study Anti-Colitis Anti-Inflammatory Colitis
The research entailed a comparative study conducted on goji berry and mulberry leaves versus their respective fruits. To determine their anti-colitis effects, the experiment was administered to C57BL/6N mice that had been induced with colitis through dextran-sulfate-sodium. Through the utilization of measures such as ELISA and western blotting analysis, researchers were able to observe how each leaf versus its corresponding fruit ameliorated colitic symptoms, tissue damage, and was able to influence the overproduction of certain pro-inflammatory cytokines.
The results showed that both the goji berry leaf and fruit significantly reduced symptoms of colitis and improved tissue damage while the mulberry leaf did not show similar improvements. The goji berry leaf exhibited the strongest performance in restraining the overproduction of pro-inflammatory cytokines and further repairing the damaged colonic barrier. It also effectively adjusted gut microbiota equilibrium by increasing beneficial bacteria and decreasing harmful ones. The berries and leaves similarly restored certain dietary fibers to alleviate inflammation, but the mulberry leaf did not achieve this for butyrate. This is the first report to provide a comprehensive contrast of anti-colitis effects between the leaves and fruits of goji and mulberry.
Long-term consumption of green tea can potentially lessen the risk of depression in postmenopausal women by decreasing inflammation and boosting estradiol levels.
2023 Nutrients Long-Term Consumption of Green Tea Can Reduce the Degree of Depression in Postmenopausal Women by Increasing Estradiol Wan Z, Qin X, Tian Y, Ouyang F, Wang G, Wan Q
Cohort Study Anti-Inflammatory Depression Green Tea
In the study, researchers performed an analysis on a tea-producing village, incorporating 386 postmenopausal women in the investigation, who participated either as green tea consumers or non-drinkers (control group). The level of estradiol, inflammation markers, sleep quality, and depression symptoms were measured to uncover any correlations.
The results reflected significant disparities between the tea-drinking and control groups in terms of depression and insomnia levels, BMI, inflammation levels, and estradiol quantities. By appraising these outcomes, it was found that green tea intake could quell the likelihood of depression via its impact on sleep, inflammation, and estradiol levels. The risk of depression was consequently seen as reduced among postmenopausal women engaging in regular consumption of green tea.
Bee-collected pollen and bee bread, particularly when artificially fermented, demonstrate significant antiviral activity against the H1N1 strain of the influenza A virus.
2023 Foods Antiviral Activity of Beebread, Bee-Collected Pollen and Artificially Fermented Pollen against Influenza A Virus Dimitriou T, Asoutis Didaras N, Barda C, Skopeliti D, Kontogianni K, Karatasou K, et al.
Experimental Study Bee Pollen Honey Influenza
The research investigated the antiviral properties of bee-collected pollen (BCP) and bee bread (BB), including versions that had undergone artificial fermentation. The experiment also assessed separate proteins, water content, and -butanol portions of these substances. The analysis evaluated their effectiveness against the H1N1 strain of the influenza A virus (IAV). The antiviral behavior of these materials was taken in lab conditions via a comparative real-time PCR analysis working on their inhibitory concentration and selectivity index.
The outcomes revealed artificial fermentation improved the antiviral effectiveness of BCP. The protein fractions within the BCP and BB presented the greatest antiviral activity. Observations also highlighted that the chemical composition, prominent in proteins, and potentially microbiome metabolism determined the antiviral properties of BCP and BB. The chemical profile analysis emphasized the existence of some specialized metabolites that might be contributing towards this antiviral action.
Consumption of tea and coffee may possibly provide anti-inflammatory effects, contributing to reduced cardiovascular risk and mortality.
2023 Pharmacological Research Coffee or tea: Anti-inflammatory properties in the context of atherosclerotic cardiovascular disease prevention Surma S, Sahebkar A, Banach M
Review Article Anti-Inflammatory Cardiovascular Disease Coffee
The methodology of this narrative review examined the potential anti-inflammatory properties of consuming tea and coffee as a factor in reducing the risk of cardiovascular disease. This was done by analyzing a plethora of studies and meta-analyses that explored the impact of diet on inflammation, with a keen focus on the consumption of these beverages. The studies looked at a variety of risk factors for atherosclerotic cardiovascular disease, including inflammation biomarkers such as C-reactive protein, along with the impact of modern lipid-lowering treatments.
In discussing the results, it was noticed that inconsistent findings were produced from the analysed studies which made a conclusive determination challenging. However, a trend was observed where drinking tea and coffee seemed to raise adiponectin levels, reduce reactive oxygen species and lower low-density lipoprotein cholesterol levels. Despite these potential anti-inflammatory properties of tea and coffee being somewhat uncertain due to various confounding factors, their consumption is still recommended as part of a healthy diet.
Phenolic extracts from turmeric and ginger have significant anti-inflammatory effects and enhance wound healing in Wistar rats.
2023 Cosmetics Effect of Phenolic Compounds Extracted from Turmeric (Curcuma longa L.) and Ginger (Zingiber officinale) on Cutaneous Wound Healing in Wistar Rats Bouchama C, Zinedine A, Rocha JM, Chadli N, El Ghadraoui L, Chabir R, et al.
Experimental Study Anti-Inflammatory Ginger Wound Healing
The study utilised the solid-liquid extraction method to obtain phenolic extracts from turmeric and ginger rhizomes. Using Wistar rats as a biological model, the researchers examined the anti-inflammatory effects of the extracts by observing the decrease in edema volume in the rat's hind paw following treatment. Moreover, the healing process of purposefully induced burns on the rat's dorsal region was monitored to evaluate the healing activity.
In the discussion of the results, it was observed that the application of creams containing the mentioned extracts resulted in complete healing after 19 days, a marked improvement compared to the control group, which only achieved 60% healing. The extracts demonstrated different levels regarding tissue repair at day 14, showing their respective potency. The study also identified diverse molecular weight distribution of phenolic compounds within the extracts, suggesting potential influence on how they affect anti-inflammatory and wound healing activities.
