Infant aged 1 month and 29 days, with no history of interest, who attended the paediatric emergency department after ingesting six drops of tea tree oil 30 minutes earlier. The product was administered by his parents due to an error when they mistook it for a vitamin D packet. After ingestion, the patient was asymptomatic and on arrival at the emergency department showed a normal physical and neurological examination. The National Toxicology Centre was contacted and, as in the previous case, informed us of the risk of gastrointestinal and neurological symptoms, and the patient was admitted for clinical monitoring. Initial capillary blood gas analysis showed discrete respiratory acidosis (pH 7.32, CO2 49 mmHg, HCO3 22 mmol/l), with subsequent normalisation. He was discharged after ten hours, remaining asymptomatic throughout.
