Royal jelly is the food on which are fed and which causes them to develop into queen bees. It is claimed to have rejuvenating virtues for human beings. This report describes a 15-year-old atopic woman who presented, 15 minutes after the intake of royal jelly, local angioedema, generalised urticaria, dysphonia and bronchospasm. She was given antihistaminics and corticoesteroids and responded well. The ingested product contains royal jelly, lactose and potassium sorbate. No anaphylactic reactions to lactose and sorbates have been described previously. Prick test to common food allergens hymenoptera venoms and pollens were negative. RAST to meletin was also negative. Blood eosinophils were 600 and total IgE 465. Non-commercial prepared specific IgE to royal jelly was positive (0.8 KU/l). Prick by prick was positive to 1/10 dilution, being negative in controls (undiluted). No oral provocation test was performed due to the risk of anaphylaxis. No reported cases of royal jelly allergy were founded in a review of the medical literature. Concluding, it is the first described case of IgE anaphylactic reaction due to royal jelly.
