INSUFFICIENT RELIABLE EVIDENCE to RATE

• Aging. Although there has been interest in using oral bee pollen for aging, there is insufficient reliable information about the clinical effects of bee pollen for this purpose.
• Allergic rhinitis (hay fever). Although there has been interest in using oral bee pollen for allergic rhinitis (hay fever), there is insufficient reliable information about the clinical effects of bee pollen for this purpose.
• Amenorrhea. Although there has been interest in using oral bee pollen for amenorrhea, there is insufficient reliable information about the clinical effects of bee pollen for this purpose.

• Benign prostatic hyperplasia (BPH). Although there has been interest in using oral bee pollen for BPH, there is insufficient reliable information about the clinical effects of bee pollen for this purpose.
• Bleeding. Although there has been interest in using oral bee pollen for bleeding, including intracranial hemorrhage, there is insufficient reliable information about the clinical effects of bee pollen for these conditions.
• Breast cancer-related hot flashes. It is unclear if oral bee pollen is beneficial for the treatment of menopause-like symptoms in breast cancer patients. Details: Preliminary clinical research in breast cancer patients suggests that taking a combination of bee pollen and honey does not reduce hot flashes or other menopause-like symptoms when compared with honey alone (91983).
• Constipation. Although there has been interest in using oral bee pollen for constipation, there is insufficient reliable information about the clinical effects of bee pollen for this purpose.
• Diarrhea. Although there has been interest in using oral bee pollen for diarrhea, there is insufficient reliable information about the clinical effects of bee pollen for this purpose.
• Diaper rash. Although there has been interest in using topical bee pollen for diaper rash, there is insufficient reliable information about the clinical effects of bee pollen for this purpose.
• Dysmenorrhea. Although there has been interest in using oral bee pollen for dysmenorrhea, there is insufficient reliable information about the clinical effects of bee pollen for this purpose.
• Obesity. Although there has been interest in using oral bee pollen for obesity, there is insufficient reliable information about the clinical effects of bee pollen for this purpose.

• Premenstrual syndrome (PMS). Oral bee pollen has only been studied in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that taking two tablets twice daily of a specific combination product (Female, Natumin Pharma) containing royal jelly 6 mg, bee pollen extract 36 mg, and bee pollen with pistil extract 120 mg per tablet over a period of 2 menstrual cycles seems to decrease some symptoms of PMS, including irritability, weight gain, and edema, when compared with placebo (12008). More evidence is needed to rate bee pollen for these uses.

POSSIBLY SAFE ...when used orally and appropriately, short-term. Bee pollen has been safely used in clinical trials lasting up to 30 days (7062,7063,12008,33973). There is also preliminary evidence that taking 2 tablets twice daily of a specific combination product containing royal jelly 6 mg, bee pollen extract 36 mg, and bee pollen plus pistil extract 120 mg (Femal, Natumin Pharma) per tablet for up to 2 months seems to be safe (12008).

WARFARIN (Coumadin) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D There is some concern that bee pollen might interact with warfarin and increase the risk of bleeding.  Details In one case report, a patient on warfarin had a stable international normalized ratio (INR) of 1.9-3.3 for 9 months. The patient's INR was found to be 7.1 after starting bee pollen granules one teaspoon twice daily for approximately one month. The patient's warfarin dose was decreased by approximately 11% in order to return the INR to the therapeutic range while continuing the bee pollen supplement (18063).

General ...Orally, bee pollen seems to be well tolerated in most patients.
Serious Adverse Effects (Rare):
Orally: Acute hepatitis, allergic reactions, interstitial nephritis, kidney failure.

Dermatologic ...Orally, a case of photosensitivity has been reported for a 32-year-old patient who took a dietary supplement containing ginseng, goldenseal, bee pollen, and other ingredients. Symptoms included a pruritic, erythematous rash that was localized to the sun-exposed surfaces of the neck and extremities. Following treatment with topical and subcutaneous corticosteroids and discontinuation of the supplement, the skin rash slowly resolved. It is not known if this effect was due to the bee pollen, one of the other ingredients, or their combination (33954).

Hepatic ...Orally, there have been two cases of acute hepatitis associated with bee pollen use. One case involved ingestion of two tablespoons of pure bee pollen daily for several months. Another case involved ingestion of 14 tablets per day of a combination herbal product containing bee pollen, chaparral, and 19 other herbs for 6 weeks (1351). In this case, it is not known if bee pollen or another herb might have caused the adverse event.

Immunologic ...Patients with a history of seasonal pollen allergies, particularly allergies to plants in the Asteraceae/Compositae family, including ragweed, chrysanthemums, marigolds, daisies, and many other herbs, are at risk for serious allergic reactions to oral bee pollen. Allergic reactions can include itching, swelling, shortness of breath, lightheadedness, and anaphylaxis (5,6,11,13480,33952,33965,91981,91984,109991). In one case, exercise may have contributed to the reaction. A 15-year-old male developed generalized urticaria, facial angioedema, and dyspnea 30 minutes into a vigorous exercise session and an hour after ingesting bee pollen granules. The patient experienced abdominal cramps within minutes of consuming bee pollen on 3 previous occasions and had a positive skin prick test for bee pollen after the anaphylactic reaction (109991). Allergy symptoms due to chronic intake of bee pollen include gastrointestinal and neurologic symptoms and eosinophilia (2627,33964).
A case of allergic eosinophilic gastropathy has been reported for a 5 year-old child who was given bee pollen daily to strengthen the immune system. Symptoms included abdominal pain, vomiting, and swelling of the eyelids and legs (91981).

Neurologic/CNS ...Orally, there is one report of dizziness in a patient who took a combination product containing royal jelly, bee pollen extract, and a bee pollen plus pistil extract (12008). It is not known if this effect was due to the bee pollen, another ingredient, or the combination.

Renal ...Orally, there is one report of a patient taking a bee pollen-containing supplement for greater than 5 months who developed breathing difficulties, edema with weight gain, and loss of appetite. The patient was diagnosed with interstitial nephritis and drug-induced acute kidney failure. The supplement was discontinued and the patient was started on hemodialysis. The patient improved after several sessions of hemodialysis (18068).

Other ...Although some research has shown a lack of mycotoxins in twenty samples of bee pollen, analysis of other ready-to-eat bee pollen products have revealed contamination with potential mycotoxin producing species, including Penicillium verrucosum, Aspergillus niger aggregate, Aspergillus carbonarius, Aspergillus ochraceus, Aspergillus flavus, Aspergillus parasiticus, and Alternaria spp. (33959,33961).
