Propolis, Henbane Syrup Helps Treat Symptoms (Cough, Sore Throat, Chest Pain, Shortness of Breath, Fever) of COVID-19 Infection


The effect of propolis plus Hyoscyamus niger L. methanolic extract on clinical symptoms in patients with acute respiratory syndrome suspected to COVID-19: A clinical trial


Phytother Res. 2021 Apr 15

The outbreak of Coronavirus disease 2019 (COVID-19) has caused a global health crisis. Nevertheless, no antiviral treatment has yet been proven effective for treating COVID-19 and symptomatic supportive cares have been the most common treatment. Therefore, the present study was designed to evaluate the effects of propolis and Hyoscyamus niger L. extract in patients with COVID-19. 

This randomized clinical trial was conducted on 50 cases referred to Akhavan and Sepehri Clinics, Kashan university of medical sciences, Iran. Subjects were divided into two groups (intervention and placebo). 

This syrup (containing 1.6 mg of methanolic extract along with 450 mg of propolis per 10 mL) was administered three times a day to each patient for 6 days. The clinical symptoms of COVID-19 such as: dry cough, shortness of breath, sore throat, chest pain, fever, dizziness, headache, abdominal pain, and diarrhea were reduced with propolis plus Hyoscyamus niger L. extract than the placebo group. However, the administration of syrup was not effective in the control of nausea and vomiting. 

In conclusion, syrup containing propolis and Hyoscyamus niger L. extract had beneficial effects in ameliorating the signs and symptoms of COVID-19 disease, in comparison with placebo groups.

Poplar Propolis Extract May Help Treat Obesity


Botanic Origin of Propolis Extract Powder Drives Contrasted Impact on Diabesity in High-Fat-Fed Mice


Antioxidants (Basel). 2021 Mar 9;10(3):411

Propolis extracts are considered as nutraceutical products with potentialities towards obesity and comorbidities management. Nevertheless, propolis extracts composition is highly variable and depends on the botanic origin of plants used by the bees to produce propolis. 

This study aims to evaluate the differential effect of poplar propolis extract powder (PPEP), Baccharis propolis extract powder (BPEP), and/ or Dalbergia propolis extract powder (DPEP) on obesity and glucose homeostasis in high-fat-fed mice. PPEP supplementation reduced high-fat (HF)-mediated body weight gain, adiposity index, and improved glucose homeostasis in male C57Bl/6J mice that were submitted to a high-fat diet for 12 weeks, whereas BPEP, DPEP, or a mix of the three PEPs did not modify those parameters. 

Adipose tissue (AT) gene expression profiling highlighted an induction of mRNA related to lipid catabolism and an inhibition of mRNA coding for inflammatory markers. Several Nrf2 target genes, coding for antioxidant enzymes, were induced in AT under PPEP effect, but not by other PEP. Interestingly, representative PPEP polyphenols mediated the induction of Nrf2 target genes cell-autonomously in adipocytes, suggesting that this induction may be related to the specific polyphenol content of PPEP. 

Whereas PPEP supplementation has demonstrated a clear potential to blunt the onset of obesity and associated comorbidities, other PEPs (from Baccharis and Dalbergia) were inefficient to support their role in preventive nutrition.

Propolis a Safe and Effective Adjunct Treatment for Hospitalized COVID-19 Patients (Coronavirus)


Efficacy of Brazilian green propolis (EPP-AF®) as an adjunct treatment for hospitalized COVID-19 patients: A randomized, controlled clinical trial


Biomedicine & Pharmacotherapy, Volume 138, June 2021, 111526

Highlights

• 124 hospitalized COVID-19 patients were randomized into three groups.
• 0, 400 or 800 mg/day of a standardized Brazilian green propolis was provided.
• Adjunct treatment with propolis anticipated hospital release by five to six days.
• The 800 mg propolis dose reduced kidney damage associated with COVID-19.
• Propolis was safe and effective as an adjunct treatment.

Background

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) promotes challenging immune and inflammatory phenomena. Though various therapeutic possibilities have been tested against coronavirus disease 2019 (COVID-19), the most adequate treatment has not yet been established. Propolis is a natural product with considerable evidence of immunoregulatory and anti-inflammatory activities, and experimental data point to potential against viral targets. We hypothesized that propolis can reduce the negative effects of COVID-19.

Methods

In a randomized, controlled, open-label, single-center trial, hospitalized adult COVID-19 patients were treated with a standardized green propolis extract (EPP-AF®️) as an adjunct therapy. Patients were allocated to receive standard care plus an oral dose of 400 mg or 800 mg/day of green propolis for seven days, or standard care alone. Standard care included all necessary interventions, as determined by the attending physician. The primary end point was the time to clinical improvement, defined as the length of hospital stay or oxygen therapy dependency duration. Secondary outcomes included acute kidney injury and need for intensive care or vasoactive drugs. Patients were followed for 28 days after admission.

Results

We enrolled 124 patients; 40 were assigned to EPP-AF®️ 400 mg/day, 42 to EPP-AF®️ 800 mg/day, and 42 to the control group. The length of hospital stay post-intervention was shorter in both propolis groups than in the control group; lower dose, median 7 days versus 12 days (95% confidence interval [CI] −6.23 to −0.07; p = 0.049) and higher dose, median 6 days versus 12 days (95% CI −7.00 to −1.09; p = 0.009). Propolis did not significantly affect the need for oxygen supplementation. In the high dose propolis group, there was a lower rate of acute kidney injury than in the controls (4.8 vs 23.8%), (odds ratio [OR] 0.18; 95% CI 0.03–0.84; p = 0.048). No patient had propolis treatment discontinued due to adverse events.

Conclusions

Addition of propolis to the standard care procedures resulted in clinical benefits for the hospitalized COVID-19 patients, especially evidenced by a reduction in the length of hospital stay. Consequently, we conclude that propolis can reduce the impact of COVID-19.

Evid Based Complement Alternat Med. 2021 Feb 24;2021:6664217

Objectives. This study aimed to evaluate the effect of propolis on cognitive function in elderly Japanese with a placebo-controlled design. 

Material and Methods. This study was performed on 79 elderly Japanese. Participants orally received either a placebo or dietary supplement containing propolis extract for 24 weeks. Cognitive function assessed by Cognitrax and various blood or urine markers were measured at pre- and postadministration. 

Results and Conclusion. Eligible data from 68 subjects (placebo: 33, propolis: 35) who completed the study were analyzed. Compared to the placebo group, the propolis group showed significant improvement in verbal memory in Cognitrax (P=0.028). Total cholesterol, LDL cholesterol, urea nitrogen, creatinine, and uric acid were significantly improved in the propolis group compared to the placebo group (P = 0.011, P = 0.004, P = 0.048, P = 0.045, and P = 0.005, respectively). However, urea nitrogen, creatinine, and uric acid fluctuated within the normal level. Furthermore, a subgroup analysis was performed on those with higher than 100 of the standardized score of the neurocognitive index indicated by the overall Cognitrax score. Significant improvements in the propolis group compared to placebo were confirmed in verbal memory (P = 0.007) and processing speed as indications for information processing ability, complex attention, and concentration (P = 0.029). No side effects were observed in any of the groups. This study demonstrates that propolis is effective in improving cognitive functions such as memory, information processing, complex attention, and concentration in elderly Japanese.

Conclusion

Propolis intake improves not only verbal memory but also information processing, attention, and concentration in a group with high cognitive function. In addition, no side effects were shown by propolis ingestion. Thus, propolis is considered a very safe food.

Thyme Honey Protects Liver From Damage by Toxins


Protective Effect of Thyme Honey against Valproic Acid Hepatotoxicity in Wistar Rats


Biomed Res Int. 2021 Feb 20;2021:8839898

Introduction: Valproic acid is a medication most commonly used in the treatment of emotional and neurological depression, psychological imbalances, epilepsy, and bipolar disorder. Dark honey, like thyme honey, contains more antioxidant compounds than other samples. The purpose of this study was to evaluate the effect of thyme honey on the potential hepatic effects of valproic acid.

Methods: In this study, 48 male rats were randomly divided into 8 groups (n = 6): G1 (control): healthy rats (normal saline 0.9%), G2: thyme honey (1 g/kg), G3: thyme honey (2 g/kg dose), G4: thyme honey (3 g/kg dose), G5: VPA (500 mg/kg), G6: VPA (500 mg/kg) and thyme honey (1 g/kg), G7: VPA (500 mg/kg) and thyme honey (2 g/kg dose), and G8: VPA (500 mg/kg) and thyme honey (3 g/kg dose). Groups G1 to G5 received the drug for 28 days. On day 14, administration of thyme honey for G6 to G8 groups was carried out using gavage until day 28. VPA was administered one hour after honey. To carry out the biochemical evaluation, blood samples were collected from all the groups and their serums were used for MDA, TAC, and liver enzymes (AST, ALT, and GGT). Tissue samples of each rat were also removed for histological studies with hematoxylin-eosin and Masson's trichrome staining.

Results: The use of thyme honey significantly improved the histopathological parameters of the liver tissue, including hypertrophic degeneration and nucleus alteration, expansion of sinusoids, fibrosis and hepatic necrosis, and inflammation as well as hypertrophy of Kupffer cells. In the groups receiving VPA, the rate of lipid peroxidation increased, which indicates the destruction of the liver cell membrane due to drug consumption. TAC levels also increased following increase in thyme honey dosage (p ≤ 0.05). The results of liver enzyme analysis showed a decrease in AST and ALT levels in the G6 group and a decrease in GGT level in the G8 group (p ≤ 0.05).

Conclusion: Based on the results of this study, it seems that high percentage of antioxidants in thyme honey enabled it to improve hepatic complications and reduce the rate of hepatocellular destruction.

Australian Jarrah (Eucalyptus marginata) Honey Contains Agents That Augment Antifungal Activity


Inhibition of Dermatophyte Fungi by Australian Jarrah Honey


Pathogens. 2021 Feb 11;10(2):194

Superficial dermatophyte infections, commonly known as tineas, are the most prevalent fungal ailment and are increasing in incidence, leading to an interest in alternative treatments. Many floral honeys possess antimicrobial activity due to high sugar, low pH, and the production of hydrogen peroxide (H2O2) from the activity of the bee-derived enzyme glucose oxidase. 

Australian jarrah (Eucalyptus marginata) honey produces particularly high levels of H2O2 and has been found to be potently antifungal. This study characterized the activity of jarrah honey on fungal dermatophyte species. Jarrah honey inhibited dermatophytes with minimum inhibitory concentrations (MICs) of 1.5-3.5% (w/v), which increased to ≥ 25% (w/v) when catalase was added. Microscopic analysis found jarrah honey inhibited the germination of Trichophyton rubrum conidia and scanning electron microscopy of mature T. rubrum hyphae after honey treatment revealed bulging and collapsed regions. When treated hyphae were stained using REDOX fluorophores these did not detect any internal oxidative stress, suggesting jarrah honey acts largely on the hyphal surface. 

Although H2O2 appears critical for the antifungal activity of jarrah honey and its action on fungal cells, these effects persisted when H2O2 was eliminated and could not be replicated using synthetic honey spiked with H2O2, indicating jarrah honey contains agents that augment antifungal activity.

Propolis May Help Treat Cold Sores, Genital Herpes (Type 1 HSV-1 and Type 2 HSV-2 Viruses)

Antiviral activity of different extracts of standardized propolis preparations against HSV


Antivir Ther. 2021 Feb 23

Background: Viral infections are among the most common problems in healthcare practice. Natural products offer great promise as potentially effective antiviral drugs. Propolis is a honeybee product with biological properties and therapeutic applications. We aimed to investigate the antiviral activity of different extracts of Standardized Propolis Preparations (M.E.D.®) with glycol, ethanol, glycerol, and soya oil, against herpes simplex type 1 (HSV-1) and type 2 (HSV-2) viruses.

Methods: Chemical composition and antiviral activity of each extract were determined. The selective index (SI=CC50/EC50) was determined as a parameter to indicate the in-vitro antiviral activity of the extracts compared to acyclovir as the control.

Results: SI values of glycol, ethanol, glycerol, soya oil extracts and acyclovir were determined as 6.8, 4.1, 2.2, 3.3, and 6.3 against HSV-1, and as 6.4, 7.7, 1.9, 4.2, and 2.9 against HSV-2, respectively. Glycolic propolis extract was found to possess a greater antiviral activity than acyclovir for both HSV type 1 and type 2, while glycolic, ethanolic, and soya oil preparations were found to have more significant activity than acyclovir for HSV-2.

Conclusions: It was determined that standardized propolis preparations have antiviral bioactivity against HSV.

Bee Pollen May Help Treat Diabetes (High Blood Sugar, Hyperglycemia)


J Agric Food Chem. 2021 Feb 5

Extract of Unifloral Camellia sinensis L. Pollen Collected by Apis mellifera L. Honeybees Exerted Inhibitory Effects on Glucose Uptake and Transport by Interacting with Glucose Transporters in Human Intestinal Cells

Bee pollen possesses potential hypoglycemic effects but its inhibitory mechanisms on glucose absorption and transportation in intestinal cells still need to be clarified. Here, we determined the inhibitory effects of bee pollen extract originating from Camellia sinensis L. (BP-Cs) as well as its representative phenolic compounds on glucose uptake and transport through a human intestinal Caco-2 cell monolayer model.

It showed that three representative phenolic compounds, including gallic acid (GA), 3-O-[6'-O-(trans-p-coumaroyl)-β-d-glucopyranosyl]kaempferol (K1), and 3-O-[2',6'-di-O-(trans-p-coumaroyl)-β-d-glucopyranosyl]kaempferol (K2), with contents of 27.7 ± 0.86, 9.88 ± 0.54, and 7.83 ± 0.46 μg/mg in BP-Cs extract, respectively, exerted mutual antagonistic actions interacting with glucose transporters to inhibit glucose uptake and transport based on their combination index (CI) and molecular docking analysis. K1, K2, and GA might compete with d-glucose to form hydrogen bonds with the same active residues including GLU-412, GLY-416, GLN-314, and TRP-420 in GLUT2.

These findings provide us a deep understanding of the mechanisms underlying the anti-hyperglycemia by bee pollen, which provide a new sight on dietary intervention strategies against diabetes.

Fighting against the second wave of COVID-19: Can honeybee products help protect against the pandemic?


Conclusions and recommendations


Bee products and bee venom are well known of their nutritional and medicinal values, they have been employed since ages for different therapeutic purposes. In this review, we comprehensively discussed the promising effects of different bee products against the emerging pandemic COVID-19, bee products possess unique criteria and harbor a magic cocktail of phytomedicines that help to protect, to fight, and to alleviate COVID-19 infection.

Honey has been recommended by the National Institute for Health and Care Excellence (NICE) and Public Health England (PHE) as a first line treatment for cough due to upper respiratory tract infection, which is the main well identified COVID-19 symptom (Wölfel et al., 2020), on the other hand variable concentrations of Manuka honey surprisingly found to modulate the release of cytokines, chemokines and matrix-degrading enzymes that regulate inflammatory and immune responses (Minden-Birkenmaieret al., 2019), currently drugs that quiet cytokine storms and soften the hyperinflammation are greatly considered to protect from acute respiratory distress syndrome (ARDS) the major cause of death due to serious COVID-19 infection (Mehta et al., 2020a). Therefore, we recommend honey as a potential compatible antiseptic prophylaxis to help protect against the virus. Honey might safely disinfect the throat and trap virus particles, beside a major advantage that it has no side effects and of great nutritional value. Furthermore, research into the active ingredients that impart antiviral potency to honey and greater understanding of how those chemicals cause their effects on viruses might help direct development of effective antiviral drugs with potentially fewer side effects. We may even consider diluted solution of natural honey as a home-made antiseptic for hands, skin and mucous membranes or as a mouth gargle since honey is completely safe and widely used as sweetener in several pharmaceutical preparations.

Propolis contains a concentrated dosage of therapeutic flavonoids and phenolic compounds that interfere with maturation and replication machinery of the virus in one hand and mitigate the exaggerated inflammatory response of COVID-19 on the other hand. Propolis belongs to the safest ecological therapies, investigational studies and confirmed anti-corona effects of chemical ingredients of propolis highlight the necessity for further investigations covering the prophylactic effect of propolis in high‐risk groups, especially individuals in close contact with COVID-19 patients, and validating the anti-corona effects of propolis.

As a powerful immune modulator, bee venom should be taken in consideration, it enhance the differentiation of T regulatory immune cells, it works like a protective vaccine that puts the immune system in a standby state to interfere with the virus. Finally, we reconsider bee product in general as a treasure trove to fight COVID-19.

Bee Bread Exhibits Higher Antimicrobial Potential Compared to Bee Pollen


Antibiotics

This study aimed at investigation of the antimicrobial potential of ethanolic extracts of bee bread (BB) and bee pollen (BP) and suspensions of these products in MHB (Mueller Hinton Broth).

We covered 30 samples of BP and 19 samples of BB harvested in Polish apiaries. Slightly lower activity was observed against Gram-negative bacteria compared to Gram-positive staphylococci. BB extracts exhibited higher inhibitory potential with minimum inhibitory concentration (MIC) values in the range from 2.5 to 10% (v/v) against Staphylococcus aureus ATCC 25923 and ATCC 29213. Most active BB extracts, namely, BB6, BB11 and BB19, effectively inhibited growth of clinical isolates of S. aureus (n = 9), including MRSA (methicillin resistant Staphylococcus aureus) strains (n = 3) at concentrations ranging from 2.5 to 5.0% (v/v).

Minimal bactericidal concentration (MBC) values were in the same range of concentrations; however, a shift from 2.5 to 5.0% (v/v) was observed for some products. The most active BP extracts inhibited the growth of reference strains of S. aureus at a concentration of 5% (v/v). Up to the concentration of 20% (v/v) three and seven BP extracts were not able to inhibit the growth of S. aureus ATCC 29213 and S. aureus ATCC 25923 respectively.

The growth of staphylococci was also importantly inhibited in suspensions of the products in MHB. No correlation between phenolic content and antimicrobial activity was observed.

Propolis May Help Heal Spinal Cord Injuries


Effect of Propolis on Neurological Recovery After Experimental Spinal Cord Injury

Turkish Neurosurgery

Aim: To examine the effect of propolis on the healing process in terms of both electrophysiological and ultrastructural parameters in a rat model of experimental spinal cord injury.

Material and methods: Thirty rats were divided into control, spinal cord trauma, and treated trauma groups with 10 rats per group. The rats were sacrificed after 10 days. Before sacrifice, all rats were neurologically assessed by electrophysiological monitoring, and immediately after sacrifice, the spinal cord was examined ultrastructurally by transmission electron microscopy (TEM).

Results: According to the electrophysiological examination, the treatment group was statistically significantly different from the trauma group. However, no statistically significant difference was found between the control and treatment groups. In terms of the TEM examination, the treatment group was significantly different from the trauma group.

Conclusion: In this study, propolis was administered just before the induction of trauma, and the findings suggest that the use of propolis has a positive effect on the healing process. This implies that in order to prevent postoperative deficits, this treatment may be preferably applied before spinal cord surgery for trauma.

Green and Red Brazilian Propolis May Help Treat Heart (Cardiovascular) Disease (High Blood Pressure, Hardening of the Arteries)


The Cardiovascular Therapeutic Potential of Propolis—A Comprehensive Review

Biology 2021, 10(1), 27

Simple Summary

Propolis, also described as bee glue, is a natural component made up of a resinous mixture of honeybee compounds from multiple botanical sources. The literature has demonstrated a variety of medicinal properties attributed to propolis due to its chemical complexity. However, the positive effects of propolis on cardiovascular health have gained little coverage. Therefore, we aimed to provide an accurate and up-to-date review of the main cardiovascular health benefits of propolis. In particular, we intend to establish the key varieties of propolis and pharmacological compounds with the therapeutic effects that are most encouraging, as well as the physiological processes by which those advantages are accomplished.

The Brazilian green and red varieties reveal the greatest number of beneficial activities among the varieties of propolis studied. While much of the cardiovascular beneficial effects appear to derive from the cumulative actions of several compounds working via multiple signaling mechanisms, some individual compounds that may enhance the existing therapeutic arsenal have also shown significant results. It is also worth exploring the prospect of using propolis as food supplements.

Abstract

Owing to its chemical richness, propolis has a myriad of therapeutic properties. To the authors’ knowledge, this is the first comprehensive review paper on propolis to focus exclusively on its major effects for cardiovascular health. The propolis compound varieties with the most promising therapeutic benefits and their respective physiological mechanisms will be discussed. Propolis displays an anti-atherosclerotic activity, attained through modulation of the plasma lipid profile and through stabilization of the fatty plaque by inhibiting macrophage apoptosis, vascular smooth muscle proliferation and metalloproteinase activity.

The antihypertensive effects of propolis probably arise through the combination of several mechanisms, including the suppression of catecholamine synthesis, stimulation of endothelium-dependent vasorelaxation and vascular anti-inflammatory activity. The anti-hemostatic activity of propolis is attributed to the inhibition of platelet plug formation and antifibrinolytic activity. By inhibiting the secretion of proangiogenic factors, propolis suppresses endothelial cell migration and tubulogenesis, exerting antiangiogenic activity. The antioxidant and anti-inflammatory activities are responsible for protection against vascular endothelial and cardiomyocyte dysfunction, mostly by the prevention of oxidative stress. Among the reviewed propolis varieties, the Brazilian green and red varieties show the largest number of beneficial activities. Further research, especially preclinical, should be conducted to assess the cardiovascular benefits of the given varieties with different compositions.

Propolis is a beekeeping product widely used in alternative medicine due to its easy accessibility. In this review, we compiled some of the biomedical properties of propolis, focusing mainly on diabetes, obesity, and cancer. Our search for information reflects the global trend to seek new alternatives for the treatment of these diseases. There is a significant volume of research on propolis that shows that it is able to help in the control of diabetes by lowering glucose levels, MDA, and pro-inflammatory cytokines, and assisting in weight loss. Furthermore, it enhances serum insulin levels, the translocation of GLUT-4, and the function of antioxidant enzymes, in addition to protecting cells and pancreatic function. In obesity, propolis has also shown benefits, with in vitro and animal models providing evidence that it induces the transcription of adiponectin and leptin, reduces the mass of visceral adipose tissue, and regulates the levels of triglycerides, non-esterified fatty acids, and cholesterol. Another relevant aspect for propolis is the data obtained on its antitumor effects related to the inhibition of the cell cycle, apoptosis, proliferation, viability, growth, and cell migration; it is notable that many of these activities continue to have selectivity towards tumor cells without affecting non-tumor cells. It is necessary to emphasize that the propolis of each geographical region has different biomedical activities due to the significant diversity that exists in its chemical composition. As a result, each geographical variant of propolis can be considered a great source of natural products, particularly terpenes and phenolic compounds, such as flavonoids. Each propolis is thus unique, requiring individual study. Despite all the attributes and virtues of propolis, several challenges remain to overcome. The first is to determine a classification in which all the properties that have been studied can be integrated as well as those that emerge from future investigations. The proposal by Bankova (2005) can function as basis for achieving adequate classification [6]. The standardization of propolis will lead to its safe and adequate consumption, to achieve this it is necessary to generate a commitment from the scientific community that works with this beekeeping product to describe the chemical composition of all the propolis extracts used in any research. Another challenge is to increase in vivo and clinical studies, since much of the available evidence of the biomedical properties of propolis is in vitro work, which, in many cases, prevents the reported activities from being directly applied in humans. Furthermore, we consider that future clinical studies should use propolis with a well-established chemical composition, since this will allow the establishment of a specific dose for each disease and the adequate treatment in infectious and non-infectious diseases. Investigation and better understanding of the properties of propolis, and phenomena such as synergism and other mechanisms of natural products, can assist in the development of new and better medicines and safe consumption treatments as complementary therapies for these diseases.

Propolis Used to Treat Gynaecological and Gastrointestinal Disorders, Cancer


...1. Helps fight cancer

One of the benefits of the bee propolis is that it has anti-cancer and anti-tumoral properties. Scientific studies are focusing on cancer treatment and propolis. Two propolis polyphenols in specific appear to be the most-effective and powerful antitumour agents. Scientists consider that propolis’ potential to obstruct cancer from growing in both human cell and animal models is probably the outcome of its capability to prevent DNA synthesis in tumour cells and its ability to persuade apoptosis of tumour cells.

2. Gastrointestinal disorder

The infestations caused by parasites usually occur in association with an infected area. The symptoms of the gastrointestinal tract infection consist of diarrhoea, nausea, abdominal pain, and bloating. Propolis has various advantages involving anti-inflammatory and antioxidant properties. Some studies reported that the clinical usage of bee propolis helps in treating viral infections. Research showed it to obstruct adherence and development of trophozoites. It prompted the separation of these parasitic structures.

3. Oral health

Excessive bacterial microflora is present in the oral cavity, and enormous bacterial growth can lead to various oral diseases. Several studies have found that propolis restricts periodontitis-causing pathogens and bacterial-plaque growth owing to its antibacterial activities. Bee propolis extract utilizes a selectively lesser cytotoxic work on human gum fibroblasts. It also helps in healing surgical injuries or wounds. Propolis extract also plays a vital role as a therapeutic agent.

4. Gynaecological care

The causes of vaginitis are vulvovaginal candidiasis and bacterial vaginosis. The reduction of lactobacillus in the vagina is a notable aspect of vaginal infections. This infection is associated with excessive development of vaginal pathogens. A study showed that the use of propolis extract resulted in an enhancement in the well-being of the vagina. It also provides symptomatic relief because of its anesthetic properties. Therefore, one can use propolis as an alternative for patients who cannot take antibiotics because of concurrent pharmacological treatment.

5. Oncological treatment

Propolis is useful in cancer treatment because of its antitumour property by activating apoptosis on cancer cells. While it kills cancerous cells, unlike chemotherapy, it does not harm the cells around it. Also, propolis minimizes the proliferation of cancer cells. Overall, it is beneficial in cancer treatments if used efficiently.
