Eucalyptus oil poisoning in childhood: 41 cases in south-east Queensland

Abstract

Forty-two cases of oral eucalyptus oil poisoning in children under 14 years of age were identified in a defined population between 1 July 1984 and 30 June 1991, and 41 were subjected to retrospective case note analysis. Thirty-three children (80%) were entirely asymptomatic. This group included all of the four children reported to have ingested more than 30 mL of eucalyptus oil. Only two of the remaining children had symptoms or clinical signs on presentation to hospital. No child required advanced life-support. There was no correlation between the amount of eucalyptus oil taken and the presence of symptoms. If the estimated volume ingested is large, or symptoms are evident, on presentation at hospital gastrointestinal decontamination should lead to a good outcome with few clinical problems. Eucalyptus oil may be a less toxic compound than has previously been believed.
