EvidenceDISCLAIMER: These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
Aromatherapy using eucalyptus has been studied for its effects on pain, depression, and feelings of satisfaction in life in arthritis patients. Aromatherapy may help reduce pain and depression, but does not appear to alter the feeling of satisfaction in life. Additional study is needed to clarify these findings.
Further research is needed to confirm anti- inflammatory and mucolytic activity before this agent can be recommended in upper and lower airway diseases.
Although commonly used in non- prescription products, there is inconclusive scientific study of eucalyptus oil or eucalyptol. Better research is necessary before a recommendation can be made.
Dental plaque/ gingivitis (mouthwash):
Although studies on combination mouthwashes show effectiveness (such as Listerine®), it is not clear that eucalyptus oil by itself is effective or safe for this purpose.
Headache (applied to the skin):
Effectiveness of eucalyptus oil applied to the skin for headache relief has not been supported with reliable human research.
Limited evidence suggests that eucalyptus essential oil may be beneficial for patients with skin ulcers when combined with antibiotics. More studies are needed to confirm these early findings.
Nicobrevin is a proprietary product marketed as an aid for smoking cessation that contains quinine, menthyl valerate, camphor, and eucalyptus oil. Despite use of this product, there is a lack of evidence suggesting benefit of this product or eucalyptus oil for smoking cessation.
Tick repellant (topical):
Preliminary research shows that Citriodiol® spray, containing eucalyptus, may reduce the number of tick bites and thereby tick- borne infections, although additional studies are warranted.
