Abstract
A 37-year-old woman had purchased “Saburon® granules” in a drugstore one month ago and took it because of headache. Just after administration, she felt distress in her pharynx. Facial swelling, flushing over the entire body, and dyspnea caused her to consult a doctor of internal medicine. Her condition was diagnosed as anaphylactic shock. She was referred to our department for further examination. Aspirin intolerance was suspected, but none of the tests for aspirin intolerance was positive. She developed erythema on the trunk after she ate cinnamon bread in the hospital. This episode made us consider the possibility that her symptom was caused by cinnamon cortex, which is commonly contained in both cinnamon bread and Saburon® granules. Skin tests were performed and led to the diagnosis of anaphylactic shock caused by cinnamon cortex.
