Eucalyptus radiata, commonly known as the narrow-leaved peppermint or Forth River peppermint, is a medium to tall tree to 30 m high.
Eucalyptus radiata has six known chemotypes of essential oil. The leaves are distilled for cineole and phellandrene based eucalyptus oils. E.radiata was the first eucalyptus species to be commercially utilized for oil by Melbourne pharmacist, Joseph Bosisto, in 1854 as “Eucalyptus amygdalina”.
