In this case report we illustrate how incorrectly prepared and cooked seeds from white lupin - a common snack among people from parts of the Mediterranean and Middle East - caused an anticholinergic syndrome in a previously healthy man. The symptoms subsided without treatment and the patient was discharged from the hospital in good health. Anticholinergic syndrome results from inhibition of the parasympatic nervous system. The symptoms commonly include dry mouth, confusion, hallucinations, fever, tachycardia, and urine retention. The syndrome may most frequently be provoked by overdose of drugs such as prometazin, hyoscyamin, and biperidin or by ingestion of plants such as belladonna, datura and henbane. The aim of this report is to increase clinicians' awareness of white lupin's anticholinergic effects.
