Eucalyptus globulus Labill. - Myrtaceae - Tasmanian blue gum, southern blue gum, (Blauer) Eucalyptus, Blaugummibaum

Large evergreen tree, native to Australia (New South Wales, Victoria), Tasmania, naturalized elswhere.
„The species name is from the Latin globulus, a little button, referring to the shape of the operculum.“

Eucalyptus leaves are rarely used as medicine. Eucalyptus oil contained in the leaves (0.5-3.5%), is much more frequently used and consists mainly of 1.8-cineole (70-95%).

„…anti-inflammatory activity of the monoterpene 1.8-cineole in asthma and a new rational for its use as mucolytic agent in upper and lower airway diseases.“ [Anti-inflammatory activity of 1.8-cineol (eucalyptol) in bronchial asthma: a double-blind placebo-controlled trial.

„The toxic effects of Eucalyptus globulus leaf oil-derived monoterpenoids [1,8-cineole, l-phellandrene, (−)-α-pinene, 2-β-pinene, trans-pinocarveol, γ-terpinene, and 1-α-terpineol] and the known Eucalyptus leaf oil terpenoids (β-eudesmol and geranyl acetate) on eggs and females of the human head louse, Pediculus humanus capitis, were examined using direct contact and fumigation bioassays… 1-α-Terpineol and (E)-pinocaveol were highly effective at 0.5 and 1.0 mg/cm2, respectively, against P. h. capitis eggs. At 1.0 mg/cm2, (−)-α-pinene, 2-β-pinene, and γ-terpinene exhibited moderate ovicidal activity, whereas little or no ovicidal activity was observed with the other terpenoids and with δ-phenothrin and pyrethrum. In fumigation tests with female P. h. capitis at 0.25 mg/cm2, 1,8-cineole, (−)-α-pinene, (E)-pinocarveol, and 1-α-terpineol were more effective in closed cups than in open ones, indicating that the effect of the monoterpenoids was largely due to action in the vapor phase.“
