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.


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 May Help Treat Diabetes, Obesity, Cancer (Cytokines, Inflammation, Fat, Diet, Cholesterol, COVID-19)

Biomedical Properties of Propolis on Diverse Chronic Diseases and Its Potential Applications and Health Benefits


The use of alternative medicine products has increased tremendously in recent decades and it is estimated that approximately 80% of patients globally depend on them for some part of their primary health care. Propolis is a beekeeping product widely used in alternative medicine. It is a natural resinous product that bees collect from various plants and mix with beeswax and salivary enzymes and comprises a complex mixture of compounds. Various biomedical properties of propolis have been studied and reported in infectious and non-infectious diseases. However, the pharmacological activity and chemical composition of propolis is highly variable depending on its geographical origin, so it is important to describe and study the biomedical properties of propolis from different geographic regions. A number of chronic diseases, such as diabetes, obesity, and cancer, are the leading causes of global mortality, generating significant economic losses in many countries. In this review, we focus on compiling relevant information about propolis research related to diabetes, obesity, and cancer. The study of propolis could generate both new and accessible alternatives for the treatment of various diseases and will help to effectively evaluate the safety of its use...


Traditional and alternative medicine is the world’s oldest form of health care and is used in the prevention and treatment of physical and mental illnesses in the present day. 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.
