Description:
Eucalyptus cloeziana is an evergreen tree that typically grows to
heights of 10–25 meters in shallower soils and up to 45 meters in deeper soils,
with some specimens reaching 55 meters in plantations. The trunk is characterized
by thick, rough, flaky to fibrous bark, brownish to grey on the trunk,
transitioning to smooth grey to orange bark on the branches. Adult leaves are
lance-shaped to curved, measuring 10–16 cm in length and 1.5–3 cm in width,
displaying a dull green color on the upper surface and a much lighter shade on
the lower side. The tree produces white flowers arranged in groups of seven,
typically blooming in December and January. The fruit is a woody, hemispherical
capsule about 0.5–0.7 cm long and wide. Distribution
and Habitat:
Native to Queensland, Australia, Eucalyptus cloeziana has been
introduced to various tropical and subtropical regions, including parts of
Africa. It thrives in open forests and woodlands on tablelands and slopes,
often becoming the dominant species in its habitat. The tree prefers
well-drained, neutral to acidic, medium-textured soils and can be grown at
elevations up to 2,350 meters. It grows best in areas where the mean annual
temperature ranges from 16–27°C, with a mean annual rainfall of 700–2,000 mm,
tolerating a dry season of up to five months. Medicinal
Properties:
There are no widely documented medicinal uses for Eucalyptus cloeziana.
However, the leaves yield up to 1.9% essential oil, with two forms
distinguished: a pinene-rich form (containing up to 78% alpha-pinene) and a
tasmanone-rich form (with up to 96% tasmanone). These compounds may have
potential applications in aromatherapy and traditional medicine.
Antioxidant Activity: The essential oil demonstrated
strong free radical scavenging abilities, with an IC₅₀ value of 2.8 µg/mL,
indicating potent antioxidant potential. Anti-inflammatory Effects: In vivo studies showed that the
essential oil exhibited significant anti-inflammatory activity, with a 68.8%
reduction in carrageenan-induced paw edema, suggesting its potential in
managing inflammatory conditions. Antinociceptive
(Pain-Relieving) Properties: The essential oil inhibited both neurogenic
(81.3%) and inflammatory pain (80.3%) in formalin-induced pain models,
indicating its analgesic potential. Antimicrobial Activity: The essential oil was effective
against several bacterial strains, including Staphylococcus aureus, Escherichia
coli, and Klebsiella pneumoniae, with inhibition zones ranging from 8.0 to
20.0 mm, highlighting its antimicrobial potential. Known
Toxicity: There are
no widely documented toxic effects associated with Eucalyptus cloeziana.
However, as with many eucalyptus species, the essential oils can be potent and
should be used with caution. It is advisable to consult local knowledge before
utilizing any part of the tree for medicinal purposes. Additional
