Eucalyptus is native to Australia, but today can now be found in 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. In fact, early Australian developers were successfully able to treat and cure fever using Eucalyptus leaves.
Eucalyptus is sold as both a supplement and is an ingredient in over-the-counter products. The supplement has been promoted for cough/bronchitis and rheumatism. Eucalyptus as an ingredient in over-the-counter 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, and is found in the 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 product be classified as a drug.
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. Eucalyptus grows in subtropical regions.
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.
Cautions and Side Effects
Eucalyptus supplementation is inadvisable for children, adolescents, older or chronically ill people, pregnant women or women who are breastfeeding, and anyone with low blood pressure, kidney problems, stomach problems, intestinal or biliary inflammation, or liver disorders. Insulin-dependent diabetics should carefully monitor blood sugar since eucalyptus may affect blood sugar levels.
Eucalyptus may affect the metabolism and clearance of drugs like phenobarbital, aminopyrine, and amphetamine by the liver. Anyone taking such medication should avoid the use of eucalyptus.
Precautions and Side Effects
Unlike the pharmaceutical companies, the manufacturers of herbs and supplements do not have the same mechanism for reporting adverse effects associated with the use of their products. Therefore data on adverse effects is limited. Life-threatening poisonings have been reported from overdoses of eucalyptus oil. Initial symptoms of toxicity are epigastric pain and vomiting, followed by central nervous system depression, and coma. Other potential adverse effects include nausea, vomiting, and diarrhea.
Only a few drops of Eucalyptus oil are enough to cause life-threatening poisoning in many children. Adults have been poisoned with only 4 to 5 milliliters. Symptoms of overdose include a drop in blood pressure, circulation problems, collapse, and asphyxiation. In the event of overdose, you should seek emergency medical treatment immediately.
