Propolis resin is under investigation for its antimicrobial properties, and use in treating antibiotic-resistant strains of microbes. This includes some of the microbes that cause yeast infections, bacterial vaginosis and aerobic vaginitis, and vaginal dysbiosis, amongst others.

Propolis has antioxidant, antimicrobial, antiviral, antiparasitic, immune-stimulating and antifungal activity. It is generally well tolerated, but it is also a well-known cause of allergic contact dermatitis — not only in beekeepers — so patch-test before using it on delicate areas, and stop if it irritates.

In our own clinic, we use propolis in vaginal pessaries as a gentle antimicrobial, among other indications.

Why isn’t propolis already used by medicine?

Propolis is known to have been used as a medicine by ancient human civilisations, and while some favour has been lost over the centuries, renewed interest in this resinous substance is occurring in western medicine pharmacy.

Because of the variability in propolis products naturally, scientific research has been slow to develop and approve products for medical complaints – standardising is an issue when it comes to potency. When a substance contains many different active parts, it can be difficult to isolate them, and we know from experience that sometimes the compounds work together, and not separately.

Traditional use has been for both internal and external complaints.

What is propolis?

Propolis is a substance produced by honey bees (bee glue), collected from living plants, used to construct and augment hives. Propolis has been demonstrated to possess antibacterial, antiviral and antifungal properties.¹ Studying propolis has had varying results, since the plants that the bees collect the resins from varies from location to location depending on local flora.

These differences in flora change the properties of the resin, making it more or less effective against various microbes, however it seems that variations in effect are minor. The type of bee doing the collecting also appears to make a difference in how potent the propolis is.

Propolis is a combination of two Greek words

Pro – in defence of Polis – the city

Meaning, in defence of the city, or beehive. Propolis keeps a beehive sterile and protected, having many effects on potential invading fungi (moulds and yeasts), bacteria, viruses and parasites. Invaders are also mummified with propolis if they are too big/heavy to take out of the hive.

What propolis is made up of

Propolis is used by bees mixed with wax to seal up the hive, fix cracks, keep moisture and temperature levels stable, and smooth the walls. It is typically made up of half plant resins, 30 per cent waxes, 10 per cent essential and aromatic oils, and five per cent each of pollen and other organic substances.

Colour varies depending on the wide range of plants used. Propolis can’t be used raw; it must be extracted and the non-useful debris and wax removed. Alcohol is most often used in this process.

Extracted propolis contains high levels of polyphenolic components, with over 500 compounds identified so far. These include:

Polyphenols – flavonoids, phenolic acids and aldehydes, simple phenols (and esters), coumarins, stilbenes and lignans
Terpenes
Fatty/waxy substances
Beeswax
Vitamins
Proteins
Amino acids
Sugars

Comparisons between studies have proven difficult due to variations in composition of the propolis. Drug resistance in microbes has not proved to be a barrier to successful treatment with propolis.

There isn’t just one component of propolis that offers its antimicrobial effects, and due to the local variances in flora, the mixture is always a bit different.

Propolis is most effective against gram-positive bacteria and yeasts, while gram-negative bacteria are less susceptible – but generally still susceptible. Some gram-positive bacteria and some yeasts are less susceptible, for example Enterococcus faecalis, Candida albicans, and Salmonella species. Research has demonstrated that using propolis with antibiotics has a synergistic effect, enhancing both the action of antibiotics and antifungals.²

Bacteria propolis has inhibited in laboratory studies:

These are laboratory (in-vitro) findings — they show what propolis can affect in a dish, not proof that it cures these infections in the body. Note too that the list includes Lactobacillus acidophilus, one of the protective vaginal bacteria: propolis is not perfectly selective, so it may knock back some good bacteria along with the bad.

Frequently asked questions

Does propolis work for BV or yeast infections?

Propolis has broad antimicrobial and antifungal activity in the laboratory, including against some BV- and yeast-related microbes, and it can work synergistically with antibiotics. But this is mostly test-tube evidence, so treat it as a promising, supportive option rather than a proven vaginal cure.²

Is propolis safe to use?

It is generally well tolerated, but propolis is a common cause of allergic contact dermatitis, so patch-test first and stop if it irritates. Its makeup varies from batch to batch, and it is not perfectly selective, so it may affect protective lactobacilli too.
