Why Propolis Might Be the Next Big Bee Byproduct


VOGUE

...Over the past few years, the benefits of propolis have slowly become more well-known, perhaps linked to the recent boom of designer honey. Manuka honey, which is thought to have antibacterial properties, can sell for up to $1,780. Propolis has admittedly experienced a much tamer ascent. When Stein searched for propolis products upon her return from Italy, the results were grim. “We were a little late to the party in North America,” says Stein. “I went back to finish up college in Canada where I’m from, and I couldn’t find these products. I found honey and manuka honey everywhere, but I couldn’t find propolis.” Stein started going to local beekeeping meetups and began making her own propolis mash-ups, using them herself or giving them to friends...

Yogurt, Propolis, Cinnamon Product Studied to Help Reduce Risk of Severe Viral Infections, Including COVID-19


Preparation and evaluation of novel functional fermented dairy products containing propolis and cinnamon


J Food Sci Technol. 2021 Oct 3;1-10

Novel functional food products might be an easy accessible and eligible approach to help reduce the risk of severe viral infections including SARS-CoV-2. Hence a product containing probiotics, propolis and cinnamon was developed and interferences of the ingredients were characterized.

Yogurts were prepared using starter cultures with propolis (0.03%) and cinnamon in various concentrations (0.3%, 1%, and 2.5%). Bifidobacterium animalis ssp. lactis, Lactobacillus acidophilus, Streptococcus thermophilus, and Lactobacillus delbrueckii subsp. bulgaricus were used as microorganisms for yogurt production. Chemical analysis revealed a decline of fat matter in the presence of propolis and/or cinnamon.

Propolis had statistically significant suppressive effects on Bifidobacterium animalis ssp. lactis as well as on Lactobacillus delbrueckii subsp. bulgaricus numbers (p < 0.05). These effects were diminished in the presence of increasing cinnamon concentrations. For Lactobacillus acidophilus a statistically significant reducing effect on the number of colonies was observed in all products investigated. Nevertheless all samples met the standard of recommended level of ≥ 106 viable cells/g of a product.

Propolis showed an inverse effect on Streptococcus thermophilus by increasing its colony numbers in yogurts. The probiotic yogurt samples containing propolis (0.03%) and cinnamon (2.5%) gained the highest number of points in the sensory evaluation compared to control.

Thyme Honey, Olive Oil Combine to Protect Against Diabetes Complications


The Synergistic Beneficial Effect of Thyme Honey and Olive Oil against Diabetes and Its Complications Induced by Alloxan in Wistar Rats

Evid Based Complement Alternat Med. 2021 Sep 20;2021:9949056

Diabetes is a metabolic disorder characterized by a chronic increase in blood glucose. Owing to the limitations observed with antidiabetics in modern medicine, medicinal plants and bee products are known as good matrices for the search for new antidiabetic molecules. 

The present study focused on the evaluation of the hypoglycemic and the protective properties of two natural products widely used in complementary and alternative medicine (thyme honey and olive oil). To achieve this, the study was carried out on Wistar rats rendered diabetic by the injection of a single dose of alloxan monohydrate (65 mg/kg body weight (BW)). 

First, the physicochemical characterization and the phytochemical analysis of thyme honey and olive oil were carried out, and then in vivo study was conducted on 42 Wistar rats divided into seven groups: three groups were normal, one group was untreated diabetic, and three groups were diabetic rats treated with thyme honey (2 g/kg BW) or olive oil (10 mL/kg BW) or their combination ((1 g/kg BW of thyme honey) and (5 mL/kg BW of olive oil)). During the experiment, the glycemia was measured regularly every 10 days. 

After 30 days of treatment, the rats were sacrificed. The serum and urine were analyzed to determine hepatic enzymes levels (AST, ALT, ALP, and LDH), lipidic profile (total cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein), and kidney parameters (urea, uric acid, creatinine, total protein, sodium, potassium, and chloride). The liver, pancreas, and kidneys were analyzed to evaluate their histological changes and to determine their enzymatic antioxidant content (catalase, GSH, and GPx) and the levels of MDA. 

The results obtained showed that thyme honey or olive oil, and especially their combination, improved significantly the blood glucose levels and they protect against metabolic changes and the complications induced by diabetes.
