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.

Inhibition of the fungal asexual reproduction stages by three Moroccan essential oils

Abstract: The effect of oregano (Origanum compactum Benth.), mugwort (Artemisia herba-alba Asso) and eucalyptus (Eucalyptus globulus Labill.) oils on spore germination, mycelial elongation and sporulation were studied in three fungi. All three stages of fungal asexual reproduction were affected, but mycelium growth was the most sensitive, followed by spore germination and then sporulation. Of the three fungi studied, Zygorrhynchus sp. was found to be the most sensitive followed by Aspergillus niger and then Penicillium italicum. Oregano oil was observed to be the most active on the three phenomena studied, followed by mugwort at spore germination and sporulation stages and eucalyptus oil when mycelial elongation was considered. The antifungal activity at all three stages of asexual reproduction was shown to be related to oil composition.

Survival, growth and productivity of tree species under evaluation for agroforestry to control salinity in the Western Australian wheatbelt

Abstract: Survival and growth were investigated for 10 Eucalyptus species and 2 fodder tree species planted for salinity control in the wheatbelt of Western Australia. After two years of growth the trees were harvested to determine fodder biomass production and yields of cineole from the eucalyptus leaf oil. Subsequent harvests were conducted at three and five years after planting. At each harvest, biomass production from fodder species was greater than from most species of eucalypts. Biomass yields from eucalypts were variable, and there were no consistent trends in the productivity of the different species for the three harvests. Leaf cineole concentrations and cineole yields were low after two years of growth, but after three and five years cineole yields were generally higher from all species. E. kochii subspp. plenissima and kochii, E. horistes, E. radiata and E. angustissima produced consistently high cineole yields after three and five years. These species appear to have potential for the production of high grade eucalyptus oil in the wheatbelt of Western Australia.
