“…Therefore, special attention should be paid to preventive measures in bee farms. The antimicrobial activity of honey and its solutions is known (Chirsanova et al, 2021;Sajtos et al, 2022). After all, by taking such mixtures, the human body acquires a strong non-specific immunity (Carnwath et al, 2014;Mustar & Ibrahim, 2022).…”

“…For example, buckwheat honey can have a bactericidal effect on gram-positive and gram-negative microorganisms due to its low pH. Rapeseed honey has antibacterial activity against Proteus Vulgaris (Subrahmanyam et al, 2001;Mulu et al, 2017;Chirsanova et al, 2021), and forest honey has anti-inflammatory and analgesic effects (Sajtos et al, 2022). In turn, sunflower honey is characterized by its ability to be easily digested due to mono sugars and other nutrients (Chirsanova et al, 2021;Sajtos et al, 2022).…”

“…Phytoncides of this type of honey suppress the growth of pathogenic microflora (Nemo et al, 2021). The antimicrobial activity of honey is of interest to practitioners and researchers, as reported by several workers (Nemo & Bacha, 2021;Zhang et al, 2021;Hossain et al, 2022;Mustar & Ibrahim, 2022;Sajtos et al, 2022), but most of these reports are pretty contradictory. Therefore, our experiment aimed to study the activity of sunflower honey against a mixed microbial association isolated from bees with signs of dyspepsia in laboratory conditions.…”

Beekeeping is one of the essential branches of agriculture in Ukraine, the main activity of which is aimed at breeding bees and obtaining honey and other products beneficial for human health. Maintaining the physiological state of bee colonies at the proper level is one of the essential tasks of veterinary medicine doctors and beekeepers. Compliance with veterinary and sanitary requirements at bee farms is the basis of preventing infectious pathologies in bee colonies. Since the body of insects has a fast metabolism, any infectious pathology quickly acquires a massive manifestation. One indicative symptom of infectious damage to the “gut” of bees is dyspepsia. Diarrhea, anorexia, and loss of productivity are observed in bees in this condition. The market of means to prevent such pathological manifestations in beekeeping is relatively narrow. The healing and favorable properties of honey, manifested in pain-relieving, antimicrobial and anti-inflammatory effects, have been known since ancient times. Sunflower honey differs from other types in a wide range of components, particularly phytoncides, which inhibit the growth of pathogenic microorganisms. Therefore, the main goal of the experiment was a laboratory study of the effect of different concentrations of sunflower honey sieve on the mixed microbial association isolated from bees with signs of dyspepsia. The activity of sunflower honey in laboratory conditions was studied by the disco-diffusion method in Petri dishes on MPA medium (meat-peptone agar). To obtain syrup from sunflower honey, sunflower honey was diluted with distilled water in a ratio of 1:1, working solutions were prepared from sunflower honey syrup in dilutions of 1:2, 1:4, 1:10, 1:100. The data analysis indicates the bacteriostatic activity of the syrup from sunflower honey in all studied concentrations concerning the mixed microbial association. Moreover, the largest diameter of the growth inhibition zone of the studied microorganisms was noted when the syrup from sunflower honey was diluted in a ratio of 1:10 (19.2 ± 0.42 mm). In turn, the antagonistic effect of the syrup from sunflower honey was observed in all dilutions concerning the mixed microbial association, where the largest diameter of the antagonism was 19.6 ± 0.27 mm when the disc was impregnated with the native working solution. Thus, it is promising to accumulate and identify a pure culture antagonist concerning a mixed culture of bacteria isolated during bee diarrhea to further create a pharmacological agent for preventing infectious pathologies of bees in unhealthy apiaries.

“…Concerning acacia honey, it is very common, and of high quality in Hungary in addition to oilseed, rape, sunflower, and forest. Hungary is considered one of the highest honey producers in the European Union [ 48 , 49 ]. In the current study, acacia honey had the highest water content among the studied honey from other plant extracts (19.2%) but had the lowest content of hydroxy-methyl-furfural (HMF) content 1.73 mg kg −1 and fructose + glucose content of 64.7%, as well as lowest values of the following nutrients (in mg kg −1 ): calcium (62.8), potassium (142), sodium (14), phosphorus (68.5), sulfur (19), and zinc (0.86), compared to other treatments.…”

The human blood sugar level is important and should be controlled to avoid any damage to nerves and blood vessels which could lead to heart disease and many other problems. Several market-available treatments for diabetes could be used, such as insulin therapy, synthetic drugs, herbal drugs, and transdermal patches, to help control blood sugar. In a double-blind human study, four kinds of honey from bees fed on acacia, sea buckthorn, chlorella alga, and green walnut extracts were used in fortifying yogurt for controlling human blood sugar. The impact of a previously fortified honey was investigated on blood levels and other parameters of healthy individuals in a human study with 60 participants. The participants received 150 mL of yogurt mixed with 30 g of honey every morning for 21 days. Before and after the study period, the basic blood parameters were tested, and the participants filled out standardized self-report questionnaires. Acacia honey was the traditional honey used as a control; the special honey products were produced by the patented technology. The consumption of green walnut honey had a significant effect on the morning blood sugar level, which decreased for every participant in the group (15 people). The average blood sugar level at the beginning in the walnut group was 4.81 mmol L−1, whereas the value after 21 days was 3.73 mmol L−1. The total decrease level of the individuals was about 22.45% (1.08 mmol L−1). Concerning the sea buckthorn and chlorella alga-based honey product groups, there was no significant change in the blood sugar level, which were recorded at 4.91 and 5.28 mmol L−1 before treatment and 5.28 and 5.07 mmol L−1 after, respectively. In the case of the acacia honey group, there was a slight significant decrease as well, it was 4.77 mmol L−1 at the beginning and 4.27 mmol L−1 at the end with a total decrease rate of 10.48%. It could thus be concluded that the active ingredients of green walnut can significantly decrease the blood sugar level in humans. This study, as a first report, is not only a new innovative process to add herbs or healthy active ingredients to honey but also shows how these beneficial ingredients aid the honey in controlling the human blood sugar level.
