For Patients & Caregivers
A few studies have investigated the efficacy of propolis in treating various conditions. However, further study is needed to determine whether propolis is an effective treatment for any of these conditions.
Propolis is a mixture of pollen, beewax, and resin that is collected by honeybees from the buds and sap of certain trees and plants. It has been used in folk medicine and in food and drinks to improve health and prevent disease. Propolis is thought to be effective against cancer, diabetes, heart disease, infections, and inflammation.
Bee pollen, found in propolis, is a mixture of plant pollens, nectar, and bee saliva that bees form into granules to store as food. It is claimed as a “cure all” by some and is thought to have antiaging and stamina increasing properties, as well as antioxidant effects. Bee pollen has been used to treat chronic inflammation of the prostate, as well as other conditions. However, aside from its nutritional value, clinical data show that the benefits of bee pollen are limited.
Allergic reactions to propolis and bee pollen have been reported. Therefore, patients who are allergic to bee venom (ie, bee stings), honey, ragweed, or chrysanthemum should not take either of these supplements. Bee pollen may increase the side effect of warfarin, a blood thinning drug.
Laboratory studies show that propolis has anticancer properties. Human data are lacking.
There is no scientific evidence to support this use.
- Heart Disease
This claim is not backed by clinical data.
A few studies show that propolis can be effective in treating ear infections.
Laboratory studies show that propolis has immunomodulatory effects. Human studies are needed.
Reported: Hypersensitivity reaction causing itching, headache, swelling, sneezing, allergic shock, elevated white blood cell levels, and inflammation of the stomach and intestines (causing nausea, abdominal pain, and diarrhea).
Case Report: A 32-year-old woman experienced a toxic reaction to sunlight (itching, rash) after taking a dietary supplement containing ginseng, goldenseal and bee pollen.
For Healthcare Professionals
Propolis is a resinous mixture of pollen and beewax collected by honeybees from the buds and exudates of certain trees and plants (1). It has been used in folk medicine and in food and beverages to improve health and to prevent disease. Propolis is thought to have antibacterial, antiviral, anti-inflammatory, antioxidant, immunostimulatory, antiproliferative, cardioprotective, and radioprotective properties (2) (3).
Clinical data show propolis to be an effective adjuvant treatment for asthma (4) and for the treatment of plane and common warts, possibly due to its immunomodulating and antiviral properties (5). A propolis/zinc suspension reduced the number of acute otitis media infections in children (6).
An in vitro study found propolis to have greater cytotoxic activity against human lung adenocarcinoma (A549) and human fibrosarcoma (HT-1080) cells compared to 5-fluorouracil (7). However, the anticancer effects of propolis have not been confirmed in humans.
Bee pollen, a constituent of propolis, is a mixture of plant pollens, nectar, and bee saliva that bees form into granules to store as food (8). It is claimed as a “cure all” by some and is touted for its antiaging and stamina increasing properties, antioxidant effects, and for chronic prostatitis, among other conditions. Aside from its nutritional value, clinical data show that bee pollen has limited benefits in improving athletic performance (9) (10).
The use of propolis and bee pollen is relatively benign. However, hypersensitivity reactions to each of these supplements have been reported. Patients who are allergic to bee venom (ie, bee stings), honey, ragweed, or chrysanthemum should not take these products. A case study reported that bee pollen may elevate the international normalized ratio (INR) above the therapeutic range in patients taking warfarin (8).
Many constituents of propolis have antitumor effects, including caffeic acid phenyl ester, quercetin, luteolin, galangin, and artepillin C (2). One of the flavonoids extracted from propolis showed a more potent cytotoxic activity against human lung adenocarcinoma (A549) and human fibrosarcoma (HT-1080) cells than did the anticancer drug 5-fluoruracil (7). Propolis was also found to inhibit proliferation and induce apoptosis in human leukemia (HL-60) cells through activation of caspase-3 via the mitochondrial pathway (2). Pretreatment of rats with orally-administered propolis extract also reduced the oxidative damage to heart mitochondria caused by an acute intraperitoneal dose of doxorubicin (3). Propolis demonstrated immunomodulatory effects in mice through increasing the expression of toll-like receptors and the production of the cytokines, IL-1beta and IL-6 (12).
Reported: Hypersensitivity reaction causing pruritus, headache, swelling, sneezing, anaphylaxis, hypereosinophilia, and eosinophilic gastroenteritis consisting of nausea, abdominal pain, and diarrhea (13).
Acute hepatitis has been reported in two patients taking bee pollen (6).
Case Report: A 32-year-old woman suffered phototoxic reaction (itching, rash) after taking a dietary supplement containing ginseng, goldenseal and bee pollen (14).
Bee pollen in propolis contains flavonoids that are known to inhibit cytochrome P450 (CYP) isoenzyme 2C9 in vitro. Because this isoenzyme is responsible for much of the hepatic metabolism of warfarin, its inhibition may elevate the International Normalized Ratio (INR) (8).
