- Dosing considerations for Eucalyptus.
Eucalyptus leaf is used for infections, fever, upset stomach, and to help loosen coughs. The leaf is also used for treating respiratory tract infections, whooping cough, asthma, pulmonary tuberculosis, osteoarthritis, joint pain (rheumatism), acne, wounds, poorly healing ulcers, burns, bacterial dysentery, ringworms, liver and gallbladder problems, loss of appetite, and cancer.
Eucalyptus oil should not be taken by mouth or applied to the skin full-strength. It must be diluted for safety. The diluted oil is taken by mouth for pain and swelling (inflammation) of respiratory tract mucous membranes, coughs, bronchitis, sinus pain and inflammation, asthma, chronic obstructive pulmonary disease (COPD), and respiratory infections. It is also used as an expectorant to loosen coughs, antiseptic, fever reducer, and in vaporizer fluids. Other uses include treatment of wounds, burns, ulcers, and cancer.
Diluted eucalyptus oil is applied directly to the skin for pain and swelling of respiratory tract mucous membranes, joint pain, genital herpes, and nasal stuffiness. It is also used as an insect repellent.
In dentistry, eucalyptus oil is included in products used as sealers and solvents for root canal fillings.
In foods, dried eucalyptus leaf is used as a flavoring agent.
In manufacturing, eucalyptus oil is used as a fragrance in perfumes and cosmetics. It is also used as a mouthwash, antiseptic, liniment and ointment, and in toothpaste, cough drops, and lozenges.
Possibly Effective for...
- Bronchitis. Some research shows that taking a specific combination product containing eucalyptol, a chemical found in eucalyptus oil, and extracts of pine and lime by mouth for at least 2 weeks improves symptoms and reduces flare-ups in people with bronchitis.
Insufficient Evidence to Rate Effectiveness for...
- Arthritis. Early research suggests that aromatherapy with a combination of eucalyptus oil, lavender, marjoram, rosemary, and peppermint oils might reduce pain and depression in people with arthritis.
- Asthma. Early research suggests that eucalyptol, a chemical found in eucalyptus oil, might be able to break up mucous in people with asthma. Some people with severe asthma have been able to lower their dosage of steroid medications if they take eucalyptol. But don't try this without your healthcare provider's advice and monitoring.
- Dental plaque. Early research suggests that chewing gum containing 0.3% eucalyptus extract might reduce dental plaque in some people.
- Headache. Early research suggests that applying a combination product containing eucalyptus oil, peppermint oil, and ethanol to the head does not reduce pain in people with headaches. However, the product might help people with headaches relax and think better.

- Bleeding gums.
- Bladder diseases.
- Liver and gallbladder problems.
