Occurrence and cultivation of eucalyptus.
As a rule, the trees can reach a height of up to 60 meters. The plants are native to Australia and the eastern part of Indonesia. However, they are also found in other warm areas of the world, including Brazil and Spain. Eucalypts have a smooth trunk. When young, their leaves have a blue-green coloration and an oval shape. The gray-green subsequent leaves are sickle-shaped, their edges smooth. The flowers of the eucalypts are whitish. Usually, the trees can reach a height of up to 60 meters. However, in Tasmania, a specimen of a giant eucalyptus with a height of almost one hundred meters was discovered. This species, which can live up to 400 years, is considered the tallest deciduous tree in the world.
Application and use
The leaves of the eucalyptus tree contain essential oil, which is obtained by steam distillation. This substance is then used for various medicinal purposes. Thus, among other things, eucalyptus oil has an expectorant effect and can therefore be used to treat colds. The positive effect is mainly due to the ingredient 1,8-cineole, of which the oil consists to a large extent. Eucalyptus oil can be found, for example, in cold capsules, baths and balms. The active ingredient is also contained in teas, drops, lozenges and cough drops. In many products, eucalyptus oil is supplemented by other essential oils, which are obtained from thyme or rosemary, for example. However, it is also available as a natural oil, for example for inhalation purposes. The flowers of the tree are also used to produce eucalyptus honey. Since eucalyptus has an antiseptic effect, it was used at the beginning of the 19th century to treat wounds and disinfect medical equipment. Eucalyptus oil must always be used in diluted form to avoid irritation of mucous membranes. Bath additives containing the active ingredient must also not be used in excessive doses. In infants and small children, the oil must not be used in the mouth and nose area. Anyone suffering from varicose veins, febrile infections, heart and circulatory problems or asthma should consult a doctor before using appropriate products. Asthma patients must never use eucalyptus oil for inhalation as a matter of principle, as this may cause asthma attacks. In addition, it must not be used by people with liver, gallbladder or gastrointestinal problems. People who do not have any of these conditions should be able to use eucalyptus oil without concern. Advice from a pharmacist regarding dosage and use may still be recommended.
