This article contains findings obtained from research on animals:
- The results from animal research studies should not be directly applied to humans and the results may not generalise to the human population.
- There may be significant differences between species in terms of physiology, physiology, and pharmacology, as well as differences in the way diseases and treatments are modelled in animals.
- Any conclusions drawn from animal research should be considered with caution and in the context of other types of research studies such as observational studies, clinical trials, and reviews of the literature.
Insights & Discussion
Manuka honey exhibits a dual role in immune modulation, triggering a pro-inflammatory response by elevating cytokine expression and neutrophil recruitment via TLR signaling, while also influencing the phenotypic and functional maturation of macrophages.
In vitro experiments using RAW 264.7 macrophages demonstrated that 1% Manuka honey significantly upregulated the expression and secretion of pro-inflammatory cytokines, including TNF-α, IL-1β, IL-6, and iNOS, as well as chemokines such as CXCL2 and CCL2. In vivo studies with C57BL/6 mice revealed a robust peritoneal response characterized by increased neutrophil recruitment and phenotypic changes in peritoneal macrophages after intraperitoneal administration of Manuka honey. Notably, this response persisted in TLR4-defective mice, suggesting independence from TLR4 and ruling out LPS contamination. However, the dependence on MyD88 protein, a crucial adaptor in TLR signaling, was evident, shedding light on the immunostimulatory properties of Manuka honey and its potential as an immunomodulatory agent in diverse disorders.
The study delineates Manuka honey's immunomodulatory actions, showcasing its pro-inflammatory impact through cytokine release and neutrophil recruitment, independent of TLR4 but reliant on MyD88 signaling. Additionally, the observed phenotypic alterations in macrophages underscore the potential utility of Manuka honey as an immunomodulatory agent across various health conditions, offering insights into its complex yet promising role in immune regulation.

Randomised Controlled Trial Dark Chocolate Ginger Honey
This test was conducted on 30 respondents who were divided into three groups, namely the positive control group (K), dark chocolate (C), and a combination of dark chocolate with herbs (C+H). Dark chocolate was combined with herbal ingredients consisting of turmeric, red ginger, moringa, sambiloto extract, and honey as a beverage 250 mL.
The study is quantitative research with quasi-experimental method. Pain measurement using the Numeric Rating Scale (NRS) sheet was given before and 2 hours after treatment. The data was analyzed using paired t-test. State the results of the values obtained the combination of dark chocolate and herbs showed a significant reduction in pain before and after treatment (p<0.05).
Honey potentially has superior results than cough medication or placebo in curtailing symptoms and enhancing sleep in children with acute cough.

Systematic Review Children's Health Cough Honey
Methodology:
This targeted review leveraged multiple databases, such as PubMed, Scopus, CENTRAL, CINAHL, and Web of Science, to extract relevant trials relating to honey's usage in treating acute child cough. By applying a systematic approach, the emphasis was on randomized controlled trials featuring children. To ensure the results' credibility, payment was done for risk-of-bias as well as the quality of the evidence. The studies were not combined owing to the absence of essential information; instead, conclusions provided a range of noticed effects for principal results.
Discussion of results:
Following rigorous screening of almost four hundred papers, a select ten were incorporated. Significant variability in biases was noticed, with two studies possessing a high risk-of-bias and six inviting some concerns. The evidence, though of low to very low quality, indicated honey's potential superiority over placebo/no treatment and cough medication, both in reducing cough frequency and improving sleep quality.
Honey intake has observed beneficial effects on various health aspects like cardiovascular, metabolic risk factors, and wound healing, primarily replacing other sweeteners.

Review Article Honey
In this comprehensive review study, the researchers went beyond just looking at one or two aspects of health; instead, they embarked on an ambitious task of reviewing forty-eight clinical trials that were published between 1985 and 2022, involving a total of 3655 subjects. The researchers aimed to critically analyze the effect of honey on multiple health indices, including, but not limited to, cardiovascular and metabolic risk factors, glucose tolerance, mucositis inflicted by chemo-radiotherapy, cough in children, and wound healing.
The evaluation and analysis of the data involved a thorough examination of the results of each of the clinical trials, consideration of several potential variables, and detailed cross-study comparisons. This broad and deep investigation allowed the researchers to draw correlations and pinpoint the beneficial influences of honey, considered a nutritious and natural food.
The results from these clinical trials saw more beneficial effects on health from honey intake when compared to neutral or negative outcomes. It was most notably effective, particularly when used as a substitute for other sweeteners. The review also pointed out the potential use of honey as a safe adjuvant to be used in combination with drugs for specific illnesses. Confidently stating that honey has clear benefits in the clinical trials analyzed, the researchers fostered a promising narrative for the further exploration and acceptance of honey as a health booster.

A systematic literature search using Scopus, MEDLINE via Ovid and Cochrane Library databases was conducted. Records were screened and identified for preclinical and clinical studies addressing the effects of HS on the FRS. Data on populations, interventions, outcomes and methodological quality were extracted. Studies were synthesised using tables and written summaries. Of the 198 identified records, six fulfilled the inclusion criteria. All six records were used for data extraction: two experimental studies using rats as the model organism and four human clinical studies of honey on female reproductive health. HS elevated the progesterone levels, restrained body weight increase, prevented uterine and vaginal atrophies in ovariectomised rats, attenuated symptoms of candidiasis and improved oxidative status in patients.
Bee honey and propolis could have potential beneficial effects as supporting treatments for COVID-19, enhancing immunity and inhibiting viral activity.
2021 Molecules Propolis, Bee Honey, and Their Components Protect against Coronavirus Disease 2019 (COVID-19): A Review of In Silico, In Vitro, and Clinical Studies Ali AM, Kunugi H
Review Article Honey
The study's methodology involved a comprehensive review of the literature on the potential anti-COVID-19 effects of bee honey and propolis, products known for their strong antimicrobial and antioxidant abilities. The researchers conducted molecular simulations to see how various flavonoids found in these products might inhibit essential viral processes. Additionally, they compared the effectiveness of propolis extracts delivered by nanocarriers to ethanolic extracts, and they examined the effects of a combination of honey and propolis on hospitalized COVID-19 patients.
The findings from the review and simulations suggested that certain flavonoids in honey and propolis may inhibit the fusion of the virus spike with host cells, interactions that cause a cytokine storm, and viral replication. Propolis ethanolic extract, rutin, and propolis liposomes displayed inhibitory action against non-structural proteins of the virus in vitro while naringin inhibited viral infection in specific cells. When delivered via nanocarriers, propolis extracts showed enhanced antiviral effects against the virus compared to ethanolic extracts. Observations of hospitalized patients suggested that those treated with green Brazilian propolis or a honey-propolis combination experienced quicker viral clearance, symptom recovery, and hospital discharge, along with lower mortality rates.
