The wood (51 lb/cu ft) is used for building, construction, joinery, and
vehicles. It is considered suitable for paper pulp (C.S.I.R., 19481976). The
red gum or manna exuding from cracks in the bark is eaten eagerly by South
African boys and has been used for making adhesives and birdlime (Watt and
Breyer-Brandwijk, 1962). Eucalyptus manna, which exudes from punctures in
summer months, is sometimes consumed. The essential oil shows the same
antiviral (influenza) effect as that of E. dalrympleana (Vichkanova et
al, 1973). Leaves inhibit Staphylococcus aureus.
The leafy twig decoction was used to bathe rheumatic limbs in South Africa.
Leaves contain 0.350.75% essential oil, of which 5065% is cineol, 5% is
pinene, and 10% is eudesmol. The "manna" contains arabinose, raffinose,
dextrose, and sucrose. The bark contains 4.88% tannin, the kino 92.7% (Watt
and Breyer-Brandwijk, 1962). The kino contains 7.1% moisture, 0.25% ash, and
92.7% catechin + tannin (C.S.I.R., 19481976).
The species is suspected to cause poisoning in koala bears, perhaps due to HCN
(0.09% HCN has been reported) (Watt and Breyer-Brandwijk, 1962).
Seedling phanerocotylar, the cotyledons reniform.
Reported from the Australian Center of Diversity, manna eucalyptus, or cvs
thereof, is reported to tolerate more frost than most species of eucalypt.

Native to Southeastern Australia, but cultivated in Argentina, California,
Hawaii, India, Peru, et al.

At Calistoga, California, Standiford and Donaldson (1982) calculated 7.8
m3/ha/yr, equivalent to 3.2 cords or 20 million kcals/ha/yr.
NAS (1980a) suggested this as a promising firewood species. Webb et al. (1980)
report wood yields of 1030 m3/ha/yr.
Browne (1968) reports the following as affecting this species: (Fungi) Fomes
robustus, F. setulosus, Inonotus chondromyelus, Phytophthora parasitica,
Polyporus portentosus, P. zonatus. (Coleoptera) Entypotrachelus meyeri,
Gonipterus scutellatus, Paropsis obsoleta, Phoracantha semipunctata, P.
tricuspis. (Hemiptera) Eriococcus coriaceus. (Lepidoptera)
