Eucalyptus grow quickly, and many species reach great heights. One of the largest species is the giant gum tree, or mountain ash (Eucalyptus regnans), which grows to a height of about 90 meters (300 feet) and a circumference of 7.5 meters in Victoria and Tasmania (24.5 feet).
Many species shed the dead outermost layer of bark in flakes or ribbons on a regular basis, whereas others have thick textured bark. The leathery leaves often hang obliquely or vertically; the majority of species are evergreen. When the flower expands, the petals adhere to form a cap. A woody cup-shaped receptacle surrounds the capsule fruit, which contains numerous minute seeds. Mottlecah, or Silverleaf eucalyptus, has the largest fruits, measuring 5 to 6 cm (2 to 2.5 inches) in diameter (E. macrocarpa).
Major species and uses
The leaf glands of many species, particularly the black peppermint tree (Eucalyptus Salicifolia) and Tasmanian bluegum (Eucalyptus globulus), contain eucalyptus oil, a volatile aromatic oil. Its primary uses are medical, and it is an active ingredient in expectorants and inhalants. Botany Bay kino, an astringent dark reddish resin obtained in a semifluid state from incisions made in the tree trunk, is produced by Tasmanian bluegum, northern gray ironbark (E. Siderophloia), and other species.
In Australia, eucalyptus wood is widely used as a fuel, and timber is widely used in construction and fencing. The black peppermint tree is one of many species of timber-producing eucalyptus.
Eucalyptus (genus Eucalyptus), is a large genus of over 660 species of shrubs and tall trees in the Myrtaceae family native to Australia, Tasmania, and nearby islands. Eucalyptus is also known as gum trees or stringybark trees in Australia. Many species are widely cultivated as shade trees or in forestry plantations throughout the world's temperate regions. Eucalyptus trees are economically one of the most valuable groups in the order Myrtales.
Eucalyptus is an aromatic herb with decongestant and expectorant properties that provide significant relief. For centuries, Vick's, a Eucalyptus rub, has been applied to the back and chest of a person suffering from a common cold or other respiratory distress. It is known to loosen mucus in the lungs, allowing it to be coughed up and expelled.
Eucalyptus also has some antibiotic properties. Eucalyptus is useful both internally and externally. Internally, the leaves used in herbal teas can help people by acting as a diuretic, an anti-diabetic, and having some anti-tumor properties.
Eucalyptus oils are almost never used internally or ingested, but a doctor may use a minuscule amount for nasal congestion, bronchial disease, and other respiratory problems on rare occasions.
Externally, Eucalyptus is used as a vapor rub, and while it is best rubbed on the chest and back, it is also good for inhalation via steam vaporizers. Some people even boil water and add a teaspoon of vapor rub to it so that an ill person can breathe in the fumes, which helps to break up congestion in the lungs. People have frequently used the same rub to treat sprains, bruises, and muscle aches and pains.
Never underestimate the power of Eucalyptus oil, which can be beneficial in a variety of ways. For starters, it is a very strong antiseptic that is used to treat pyorrhea, a gum disease. It is also frequently used to treat burns. Insects do not like Eucalyptus, so if you mix some with water and put it in a spray bottle, you can be sure that bugs will stay away.
A small drop on the tongue is said to relieve nausea. Many people will soak a cloth in Eucalyptus oil and place it in their pantries or closets to keep bugs and roaches at bay. Another quick tip is that a few sniffs of Eucalyptus are said to help someone who has fainted and, when combined with cinnamon, are known to relieve flu symptoms.
Eucalyptus is also commonly used in aromatherapy because it is extremely beneficial when combined with other oils. Eucalyptus has stimulating and balancing properties, and its scent is very woody. It combines well with Juniper, Lavender, and Marjoram in aromatherapy. When used in aromatherapy, eucalyptus benefits the body by relieving mental fatigue, improving mental clarity and alertness, sharpening the senses, refreshing and revitalizing, stimulating, and energizing.
It also has a cooling effect on the body, relieving pain and sore muscles, breaking up congestion, and reducing inflammation. Aromatherapy combined with eucalyptus provides pure enjoyment. Inhaling the fragrance of Eucalyptus can help relieve stress and depression. It contributes to a general sense of well-being. Eucalyptus is excellent for both bathing and massage oils.
