Is eucalyptus poisonous?
Eucalyptus oil
The probable lethal dose of pure eucalyptus oil for an adult is in the range of 0.05 mL to 0.5 mL/per kg of body weight.[20] Because of their high body-surface-area-to-mass ratio, children are more vulnerable to poisons absorbed transdermally. Severe poisoning has occurred in children after ingestion of 4 mL to 5 mL of eucalyptus oil.[21]
Eucalyptus crucis
Eucalyptus crucis, commonly known as the silver mallee, is a eucalypt that is native to Western Australia.
