What Exactly Are Eucalyptus Leaves

Eucalyptus leaves are the sole diet of koala bears.


Eucalyptus leaves are probably most famous as the exclusive cuisine of koala bears. They also provide many benefits to humans. An estimated 700 species of eucalyptus trees grow in Australia. The variety humans most often harvest is Eucalyptus globulus "Australian fever tree." Native to Australia and Tasmania, Australian fever tree is grown commercially in Mediterranean and subtropical regions, including Spain and Morocco. People value eucalyptus leaves for their medicinal, aromatic and decorative properties.


Eucalyptus Leaves


Eucalyptus trees range in size from small shrubs that grow only a few feet high to giant gum trees, such as the Australian fever tree that stretches up to 230-feet tall. The leaves of the trees are just as diverse. Although their size, shape and color varies, eucalyptus leaves are generally leathery to the touch, hang vertically or at an angle and contain fragrant oil. The leaves of the Australian fever tree --- those most commonly used in medicinal remedies --- are 4 to 12 inches long, dark green and shiny.


Medicinal Uses


People have been using eucalyptus leaves for their healing properties for ages. Australian Aborigines have traditionally used the leaves to make a tea for treating high fever. Even today, some use eucalyptus tea to soothe sore throats and treat bronchitis and sinusitis. Most modern medicinal treatments use the oil extracted from the leaves and the branch tops of the plant. Eucalyptus oil can be found in many cough drops, syrups and vapor rubs. Because of its strong odor, some aromatherapists recommend using eucalyptus oil to revive someone who has fainted. Its antiseptic and antibacterial properties may aid in healing cuts, sores and other skin wounds. Eucalyptus oil is believed to be an anti-inflammatory, and it has been used to relieve arthritis pain. It even has been used as an insect repellent to guard against mosquitoes and fleas.


Home Uses


Eucalyptus leaves are common in dried flower arrangements and wreaths. The dried leaves are pretty and aromatic. Placed throughout the home, they emit a smell that many find pleasant, making eucalyptus leaves a natural air freshener. While lovely, eucalyptus leaves are not safe for children and pets; they should be kept safely out of reach if displayed in the home.


Cautions


The University of Maryland Medical Center recommends that certain individuals in high-risk groups use caution when considering the use of medicines or treatments containing eucalyptus oil. The center specifically recommends that the following populations not use eucalyptus: individuals with liver and kidney disease, those with low or high blood pressure and pregnant and breastfeeding women. Eucalyptus oil can trigger an asthma attack, so asthma sufferers should steer clear of the herb. Since eucalyptus oil could interact with other drugs, those currently taking medications should consult their physicians prior to using eucalyptus.
