What is this product used for?
Eucalyptus oil is found in many cough and cold products to help with treatment of stuffy nose and cough. Although some studies show that cough and cold products that contain eucalyptus oil can provide temporary relief for stuffy nose and cough, there isn’t enough evidence to conclusively support this claim.
Eucalyptol, one of the active chemicals found in eucalyptus oil, is thought to have antibacterial properties. It is added to mouthwashes to help reduce tooth decay and gingivitis caused by bacteria, and is also used in products that are applied to the skin to treat wounds, burns, and ulcers. Several well-designed studies have shown that mouthwashes containing eucalyptus oil or eucalyptol in combination with other ingredients can reduce dental plaque and gingivitis. It is not clear if eucalyptus oil or eucalyptol would be useful for this purpose on its own.
Eucalyptus oil is also thought to reduce inflammation, and people have used it for conditions associated with inflammation, including arthritis, asthma, and bronchitis. The effectiveness of eucalyptus oil for inflammatory conditions has varied, although a combination product containing eucalyptol is possibly effective for bronchitis, according to some research. However, further research is required.
Eucalyptus has also been used as an insecticide in many repellent sprays.
To date, research results on the use of eucalyptus oil alone are not conclusive to prove any of the health claims associated with the herb.
