Sources & What to Look For
Eucalyptusglobulus(E.globulus) is a common type of eucalyptus used for medicinal purposes, including treatment for cold symptoms or pain relief.E. globuluscontains antioxidant properties and several plant chemicals; this tree’seucalyptus leavesare used to make eucalyptus oil.
Eucalyptus oil also has many substances—but mostly eucalyptol. These plant chemicals makeE. globuluseffective.However, more research is needed to confirm the health benefits of eucalyptus.
In the United States, the Food and Drug Administration (FDA) does not regulate supplements the way it regulates prescription drugs. That means some supplement products may not contain what the label says. Whenchoosing a supplement, look for independently tested products and consult a healthcare provider, registered dietitian nutritionist (RD or RDN), or pharmacist.
Uses of of Eucalyptus
While more, extensive research is necessary regarding efficacy (its ability to produce a desired effect), people useE. globulusor eucalyptus oil to treat various health conditions.
Research is most robust forE. globulus’s effects concerning the following:
Antioxidant Effects
In onein vitrolab study (tests performed outside a living organism, in a lab setting, such as in a test tube), extracts fromE. globulusleaves reduced oxidative stress in SH-SY5Y cells (cells that serve as a model to studyneurodegenerative disorders).
In general, oxidative stress is when there aren’t enough naturally occurring antioxidants in your body to attack unstable atoms known asfree radicals. Free radicals can damage components and systems within the body, includingDNA.
Study results suggest the positive antioxidant effects ofE. globulusleaf extracts.
However, as this study was on a cell line,future high-quality clinical trials are needed to determine if these antioxidant effects apply to humans.

Cold Symptoms
In a review article, data from several studies supported inhaling (breathing in) eucalyptus oil in children or adults to relievecoldsymptoms, such as nasal congestion, nighttime coughing, and sleep problems.
While these results were positive, many clinical trials studied the effects of aromatic ointments containing eucalyptus oil mixed with other essential oils.
For this reason, it’s difficult to know the effects of just eucalyptus oil. Also, some clinical trials only had a small number of participants, meaning the samples were too small for the results to be conclusive.
In general, further research with high-quality, larger studies is still necessary to better evaluate the effects of eucalyptus oil.
Pain
A 2021 systematic review (a methodical review of a collection of studies) included a small clinical trial on the effects of an ointment containing eucalyptus oil.
When applied to the study participants' forearms, the eucalyptus oil–based ointment increased blood flow to the application sites.
This suggested that the ointment may temporarily relieve minor muscle aches. Although the results were positive, the ointment contained ingredients and eucalyptus oil.
Therefore, it’s difficult to determine if the benefits came from the eucalyptus oil or the other ingredients in the ointment.
In another small clinical trial, participants inhaled eucalyptus oil for 30 minutes three days after totalknee replacement surgery. By the end of the study, participants reported lesspainand had decreasedhypertension(high blood pressure).
In another small study, a group of participants withrheumatoid arthritis(RA) inhaled eucalyptus oil for five minutes three times daily for one month. In the third and fourth weeks of using eucalyptus oil, this group reported less pain and improved quality of life.
Further research with a larger group of participants is needed to determine eucalyptus oil’s effects fully.
Relaxing Effects
In a small study conducted on 62 preoperative individuals, eucalyptol and eucalyptus oil group participants reported lessanxietybefore their procedure than participants not using the oils—with eucalyptol showing a greater effect than eucalyptus oil.
Eucalyptol is a substance in eucalyptus oil. While eucalyptus oil contains numerous substances, eucalyptol makes up a big percentage of the components in eucalyptus oil.
These results are promising, but additional research with higher quality and larger studies is still necessary.

What Are the Side Effects of Eucalyptus?
As with many medications and natural products, E. globulus and eucalyptus oil can have side effects.
Common Side Effects
Eucalyptus oil is on the FDA’s list of approved substances added to food, but it is often used in small amounts.
More research on E. globulus and eucalyptus oil safety is necessary, but common side effects includestomach upsetandnausea.
Severe Side Effects
Possible serious side effects may include:
If you’re having a severe allergic reaction or if any of your symptoms feel life-threatening, call 911 and get medical help right away.
A healthcare provider may advise againstE. globulususe if any of the following applies to you:
Severe allergic reaction: AvoidE. globulusif you have a known allergy to it or its ingredients or parts, such as eucalyptus oil. If you’re unsure if it’s safe for you, ask a pharmacist or healthcare provider for a complete list of the ingredients.
Pregnancy and breastfeeding:E. globulusproduct labels are unlikely to targetpregnantorbreastfeedingpeople.
Moreover, more research on E. globulus and eucalyptus oil safety is necessary for these groups.Before usingE. globulusor eucalyptus oil, contact a healthcare provider to discuss the benefits and risks.
Adults over age 65: While older adults have participated in a eucalyptus oil–based study, more extensive research with more older individuals is still necessary to assess the safety ofE. globulusand eucalyptus oil in this age group.
Moreover, some older adults may have a higher likelihood of medication side effects. For this reason, use caution withE. globulusand eucalyptus oil.
Children: Very fewE. globulusproduct labels directly target infants and children.
While children have participated in eucalyptus oil–based studies, sample sizes were small. Therefore, higher-quality, larger studies are necessarily better for evaluating the safety of E. globulus and eucalyptus oil.
Talk with a healthcare provider if you’re consideringE. globulusor eucalyptus oil for your child.
Blood pressure:E. globulusand eucalyptus oil may affect your blood pressure.
For this reason, a healthcare provider may want to closely monitor you and make the necessary adjustments to your blood pressure medications if you use eucalyptus.
Lung conditions:E. globulusand eucalyptus oil may affect your breathing.
A healthcare provider may want to closely monitor you and adjust your medications accordingly if you have a lung condition, such asasthmaorchronic obstructive pulmonary disease(COPD).
Seizures:E. globulusand eucalyptus oil may raise your risk of seizures.If you have a history of seizures, a healthcare provider may advise against eucalyptus use or want to monitor you closely before adjusting your medications.
Animals: Toxicity from essential oils—like eucalyptus oil—is possible in animals. In animal studies, rats and mice experienced liver, kidney, and fertility problems.
In dogs and cats, there were reports of depression and muscle movement problems in one study.As a result, before using essential oils on or around animals, contact your veterinarian to discuss the benefits and risks.
Surgery: Because eucalyptus may affect blood sugar levels, there is a concern that it might make blood sugar control difficult during and after surgery.
Individuals should talk with their healthcare provider if they consider using eucalyptus oil before a medical procedure.
