Curiosities: This eucalyptus essential oil harvested in Angola is dominated by 1,8-cineole, alpha-pinene and p-cymene. It is a less known and rarer essential oil with regards to other essential oils from the genus As such, it can have some interest in more niche perfumery or cosmetic applications.

In ancient times, aboriginal people used eucalyptus plant for several purposes, mostly as medicine and as food. Nowadays, the plant is used in forestry to make timber, fuel, paper pulp, environmental planting as water and wind erosion control, as a source of essential oil for medicinal and perfumery industries and for arts and craft.

Traditionally it is also used to support the release of mucous in the respiratory tract

Scientific Evidence

Effect Route used in the experiment Source
Antibacterial activity Various methods – E. robusta essential oil showed a maximum zone of inhibition of 11 mm against Lactobacillus, Staphylococcus aureus,

E. coli.

 [2]
Antifungal activity Various      methods      –

Candida                       albicans, Phytophthora cactorium

 [2]
Antioxidant and anti-cancer activity (leaf extract) Assessment    of         growth inhibition on cancer cell lines –         The   powdered extract also possessed potent antioxidant capacity,    which          were comparable to ascorbic acid and α-tocopherol. These             data     also demonstrated       potent anti-cancer   activity         of against    a          variety  of cancer                cell      lines, including       pancreatic

cancer.

 [3]
Antimicrobial activity Agar diffusion method – The E. robusta oil presented the highest growth inhibition for all the microorganisms

tested.
