Bee Products May Cause Allergic Reactions
Including: acute oral, pharyngeal, and laryngotracheal edema with respiratory distress; autoimmune hepatitis; edema, rash, and urticaria; allergic reaction with chest pain. Other serious reactions include bleeding, hepatitis, and epileptic seizures.
Canada’s Drug Adverse Reaction Bulletin, Issue 2, 2005, issued a warning: bee products carry risks of allergic reactions, urging public and medical professionals to remain vigilant.
Bee products include bee pollen, royal jelly, and propolis. Bee pollen may originate from various plants, including common allergenic pollens (e.g., ragweed). Royal jelly is secreted by worker bees’ hypopharyngeal and mandibular glands. Propolis is a mixture of poplar resin, conifer bud exudates, and beeswax. These products are sold individually or mixed in various commercial forms, ranging from health supplements to treatments for allergies and asthma.
From January 1, 1998, to October 30, 2004, Health Canada received 14 reports of suspected adverse reactions attributed to bee products (10 severe cases). Four suspected allergic reactions included: acute oral, pharyngeal, and laryngotracheal edema with respiratory distress; autoimmune hepatitis; edema, rash, and urticaria; allergic reaction with chest pain. Other severe reactions included bleeding, hepatitis, and epileptic seizures. Due to confounding factors (e.g., coexisting diseases, concurrent medications), the exact cause of many cases could not be definitively attributed to bee products.
Literature confirms bee products can trigger allergic reactions. Studies also suggest no direct link between bee venom allergy (stings) and allergy to bee products. Individuals with atopy or asthma face increased risk of allergic reactions after consuming royal jelly-containing products. Patients with seasonal allergic rhinitis (e.g., pollen allergy) also face higher risk of severe allergic reactions to bee pollen.
The bulletin warns that bee pollen, royal jelly, or propolis-containing products are easily accessible to the public, but labels often fail to mention potential adverse reactions—public and medical personnel should be aware.
