The leaves contain 0.1 - 0.4% essential oil, 77% of which is cineol There is some cuminal, phellandrene, aromadendren (or aromadendral), and some valerylaldehyde, geraniol, cymene, and phellandral. The leaves contain 5 - 11% tannin. The kino contains 45% kinotannic acid as well as kino red, a glycoside, catechol, and pyrocatechol. The leaves and fruits test positive for flavonoids and sterols. The bark contains 2.5 - 16% tannin, the wood 2 - 14%, and the kino 46.2 - 76.7%. A fast growing tree with wide-ranging roots, it can be planted in soil stabilization schemes and can also be planted in marshy land where it will help in draining the land, thereby destroying a potential breeding site for mosquitoes. It is planted in S. Italy for this purpose.The wood, durable, easy to saw, yet resistant to termites, is widely used in Australia for strong durable construction, interior finish, flooring, cabinetry, furniture, fence posts, cross-ties, sometimes pulpwood. Australian aborigines made canoes from the bark. According to NAS (1980a), annual wood yields are around 20 - 25 m3/ha in Argentina, 30 m3 from Israel, 17 - 20 from Turkey in the first rotation, and 25 - 30 in subsequent coppice rotations. On poor arid sites yields are only 2 - 11 m3 on 14 or 15 year rotations.
The plant is an aromatic, astringent, tonic herb that sticks to the teeth and turns the saliva red. The report says that the leaves, essential oil and oleo-resin are used, but does not specify which properties apply to the different parts of the plant[K]. The leaves and the oil will have very similar properties, the oil being much stronger in its effect since it is distilled from the leaves[K]. Detailed below is how the oleo-resin and oil are commonly used in other species[K].
The essential oil obtained from various species of eucalyptus is a very powerful antiseptic, especially when it is old, because ozone is formed in it on exposure to air. It has a decided disinfectant action, destroying the lower forms of life. The oil can be used externally, applied to cuts, skin infections etc, it can also be inhaled for treating blocked nasal passages, it can be gargled for sore throat and can also be taken internally for a wide range of complaints. Some caution is advised, however, because like all essential oils, it can have a deleterious effect on the body in larger doses. An oleo- resin is exuded from the tree. It can also be obtained from the tree by making incisions in the trunk. This resin contains tannin and is powerfully astringent, it is used internally in the treatment of diarrhoea and bladder inflammation, externally it is applied to cuts etc.Treats throat ailments.

Fairly frost resistant, plants survive temperatures down to at least -7°c in Australian gardens. This figure is not directly relatable to British gardens, however, because of our cooler summers and colder, wetter winters. It could be worthwhile giving this species a try in the milder areas of the country[K]. Some Provenances can tolerate temperatures down to about -5°C and up to 20 frosts per year. Eucalyptus species have not adopted a deciduous habit and continue to grow until it is too cold for them to do so. This makes them more susceptible to damage from sudden cold snaps. If temperature fluctuations are more gradual, as in a woodland for example, the plants have the opportunity to stop growing and become dormant, thus making them more cold resistant. A deep mulch around the roots to prevent the soil from freezing also helps the trees to survive cold conditions. The members of this genus are remarkably adaptable however, there can be a dramatic increase in the hardiness of subsequent generations from the seed of survivors growing in temperate zones. Trees are liable to shed branches, especially in hot weather. This is said to be the most widely distributed eucalyptus tree in Australia, ranging over 23° lat. in most of arid and semiarid Australia but not the humid eastern and south-western coasts. It is regarded as one of the most widely planted eucalypts in the world with more than 500,000 ha planted. It is planted in Europe, especially in Italy, as a timber crop, for soil stabilization and as an anti-malarial measure. Some provenances coppice well for six or more rotations, on good sites, plantations are managed on coppice rotations of 7 - 10 years. Eucalyptus monocultures are an environmental disaster, they are voracious, allelopathic and encourage the worst possible attitudes to land use and conservation. Plants are shallow-rooting and, especially in windy areas, should be planted out into their permanent positions when small to ensure that they do not suffer from wind-rock. They strongly resent root disturbance and should be container grown before planting out into their permanent position. Survivalists in Australia and elsewhere might learn how the aborigines obtained water from the superficial roots, usually those ca 3 cm in diameter. The roots were excavated or lifted to the soil surface. Then the root was cut into segments ca 45 cm long, debarked, held vertically, and blown into, the water then draining into the receptacle provided.The flowers are rich in nectar and are a good bee crop.
