Information About Eucalyptus

There are many species of eucalyptus. Some are the size of an ornamental shrub, and some grow to be giant trees. The type of eucalyptus that is most often used as medicine is called blue gum or Australian fever tree. It can grow as high as 230 feet. Its 4 - 12 inch leaves are dark green and shiny. Its blue-gray bark peels to reveal a cream-colored inner bark.


Oil from the eucalyptus tree (Eucalyptus globulus) is used today in many cough and cold products, to relieve congestion. Eucalyptus oil is also found in creams and ointments used to relieve muscle and joint pain, and in some mouthwashes.


The eucalyptus tree is native to Australia and serves as the main food for koalas. The oil was used in traditional Aboriginal medicines to heal wounds and fungal infections. Teas made of eucalyptus leaves were also used to reduce fevers. Eucalyptus soon spread to other traditional medicine systems, including Chinese, Indian, and Greek and European.


In 19th-century England, eucalyptus oil was used in hospitals to clean urinary catheters. Laboratory studies later showed that eucalyptus oil contains substances that kill bacteria. It also may kill some viruses and fungi. Studies in animals and test tubes also found that eucalyptus oil acts as an expectorant, meaning it loosens phlegm.


Eucalyptus is recommended for use in the case of a chest infection as it is a power expectorant and is especially worthwhile in fighting serious chest infections such as pneumonia and bronchitis. In its diluted form, Eucalyptus oil can be applied topically to the skin as a sinus or chest rub and will have a warming effect on the area.


Eucalyptus is native to Australia, but today can be found growing in subtropical regions worldwide. One of the first recorded medicinal uses of Eucalyptus was by the Australian aborigines, who not only extracted valuable water from its roots, but used its leaves to relieve fevers. It has been reported that early Australian developers were able to successfully treat and cure fever using Eucalyptus leaves.


Eucalyptus supplements have been promoted for cough/bronchitis and rheumatism. Eucalyptus as an ingredient in drugs is used for temporary relief of minor aches and pains of muscles and for temporary relief of nasal congestion and coughs associated with a cold.


The medicinal properties of Eucalyptus reside in its oil, which is extracted from the fresh leaves and branch tips, as well as dried leaves. Eucalyptus leaf (Eucalypti folium) is an approved remedy of the German Government's Federal Institute for Drugs and Medical Devices (Commission E) for catarrhs of the respiratory tract. Eucalyptus oil (Eucalypti aetheroleum) is approved for internal and external catarrhs of the respiratory tract and externally for rheumatic complaints. Approval by Commission E should not be considered the equivalent of FDA approval. The FDA has a much higher standard and requires the establishment of absolute certainty of safety and efficacy of any product intended to diagnose, cure, mitigate, treat, or prevent disease and demands that such products be classified as a drug.


What's It Made Of?

The leaves and oil of the eucalyptus plant are used as medicine. Eucalyptus oil consists of the volatile oil made from the fresh leaves and branch tops of the eucalyptus plant. Eucalyptus leaves contain tannins, which are believed to help reduce inflammation; flavonoids, plant-based antioxidants; and volatile oils.


Available Forms

Eucalyptus oil is available in many products, including liquids and ointments. The leaves of the eucalyptus plant are available fresh, dried (to be used in teas), and in liquid extracts. Commercial cough drops, syrups, vaporizer fluids, liniments, toothpastes, and mouthwashes may contain eucalyptus oil or its active ingredient, cineole.

Are there safety concerns?

Eucalyptus leaf is safe when consumed in the small amounts found in foods. There isn't enough information to know if supplements that contain larger amounts of eucalyptus leaf are safe.


Eucalyptus oil is UNSAFE when it is either taken by mouth or applied directly to the skin without first being diluted. Taking 3.5 ml of undiluted oil can be fatal. Signs of eucalyptus poisoning might include stomach pain and burning, dizziness, muscle weakness, small eye pupils, feelings of suffocation, and some others. Eucalyptus oil can also cause nausea, vomiting, and diarrhea.


Eucalyptol, a chemical that is removed from eucalyptus oil and used as medicine, appears to be safe when taken by mouth for up to 12 weeks.


Special precautions & warnings

The use of herbs is a time-honored approach to strengthening the body and treating disease. Herbs, however, contain components that can trigger side effects and that can interact with other herbs, supplements, or medications. For these reasons, herbs should be taken with care, under the supervision of a health care provider qualified in the field of botanical medicine.


Eucalyptus oil is generally safe when applied to the skin of adults. Don' t apply eucalyptus oil, salve or chest rub to the face or nose of a child under 2.

Health Benefits of Eucalyptus

Eucalyptus supplements are derived from the fresh leaves and branch tips as well as the dried leaves of the tree known as Eucalyptus Globulus, Eucalyptus fructicetorum, and Eucalyptus smithii. The primary active constituent in eucalyptus leaves is the volatile oil euclyptol. For eucalyptus to provide an effective expectorant and antiseptic action, the volatile oil should contain at least 70 eucalyptol. Eucalyptus oil has been compared to menthol because it acts on receptors in the nasal mucosa, which help to alleviate nasal congestion.


Although eucalyptus oil has been used orally to treat some conditions, the oil is toxic when taken by mouth and must be diluted. You should not take eucalyptus oil by mouth unless your doctor tells you to.


Following are some of the health benefits of eucalyptus oil:



Cough and cold

Eucalyptus is used in many medicines to treat coughs and the common cold. It can be found in many lozenges, cough syrups, rubs, and vapor baths throughout the United States and Europe. Herbalists often recommend using fresh leaves in teas and gargles to soothe sore throats and treat bronchitis and sinusitis.


Ointments containing eucalyptus are also applied to the nose and chest to relieve congestion. Eucalyptus oil helps loosen phlegm, so many people inhale eucalyptus steam to help treat bronchitis, coughs, and the flu.


Plaque and gum disease

Eucalyptus oil is also rich in cineole, an antiseptic that kills bacteria that can cause bad breath. Eucalyptus is used in some antiseptic mouthwashes, along with other oils, and the mouthwashes have been shown to help prevent plaque and gingivitis.


Other uses

On the skin, eucalyptus oil has been used to treat arthritis, boils, sores and wounds. The oil is also used in some insect repellents, and one study found that an oil of lemon eucalyptus product may also keep ticks away.




How to Take It

Pediatric

Do not give a child eucalyptus orally (by mouth), as it is toxic. Do not give cough drops containing eucalyptus to children under 6.


For a cold, don' t apply eucalyptus oil, salve or chest rub to the face or nose of a child under 2. Ask your doctor before using eucalyptus oil as a chest rub for your child or to inhale steam for congestion.


Adult

Do not take eucalyptus oil orally (by mouth) except under your doctor' s supervision, as it is toxic.


Eucalyptus oil (for topical application): add ½ - 1 ml (15 - 30 drops) of oil to 1/2 cup of carrier oil (sesame, almond, olive, etc.). For inhalation, add 5 - 10 drops of oil to 2 cups boiling water. Place towel over head and inhale steam.


What dose is used?

The appropriate dose of eucalyptus depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for eucalyptus.

I never am without this May 15, 2009, By Gwen Gamboa From Florida

I mix this in Grapeseed oil together with pepermint and rosemary oil. Great for back rubs when kids and adults have cough. I also use for sore muscle massage after intense exercise.



Used to prevent fleas bites December 15, 2007, From California

I read using Eucalyptus oil can help prevent flea bites. I am currently using this product and so far no flea bites. Remember you must blend this oil with other bland oils like almond oil. I thought if I used this oil I will smell like Eucalyptus all day long. Not true. It evaporates into your skin and the odor will dissipate within time. I am hoping this will contine to work to ward off fleas.

The Eucalyptus oil is perfect especially in the cold dry winter. A few drops on a cotton ball and you feel totally refreshed as the scent drifts thru the house. A drop or two in a hot shower clears and opens up all your senses. …



Love it! December 27, 2009, From Arizona

This is a great product and has many uses. … people don't know about all the wonderful things this oil does because the price would probably be higher. Yippee for me. I actually make a homemade pesticide with it and it works better than any harmful chemicals that are out there. I love it and it smells great.
