A 49-year-old woman presented to the emergency room with difficulty in breathing, drooling, and fever. Twelve hours before her admission she had ingested 40 drops of pure nonheated peppermint oil (Mentha piperita– 100% pure etheric oil). The patient had used this product many times in the past while suffering from a common cold, each time ingesting 1 or 2 drops. Following these repeated administrations the patient had never had from any form of an allergic reaction. On physical examination, the patient had tachypnea of 24 breaths per minute, inspiratory stidor, excess salivation, tachycardia of 132 beats per minute, fever of 39°C, multiple burns in the entire oral cavity and pharynx, edema of the upper and lower lips, and edema of the tongue, uvula, and soft palate (Fig 1. Laryngoscopy revealed a cherry-red and swollen epiglottis, hypo-pharyngeal and laryngeal mucosal burns, and pooling of saliva in both pyriform sinuses (Fig 2). The patient was transferred to the operating room where a trans-nasal awake intubation was performed. She was treated with intravenous steroids and antibiotics and underwent successful extubation 24 hours later. The edema and the burn signs resolved gradually over the next 2 weeks.
