Eucalyptus (Eucalyptus globulus) is an evergreen tree that’s native to Australia, but now grows in many areas of the world. The eucalyptus tree has long, green leaves that give off an earthy, menthol-like scent. The leaves are hearty and indigestible in their whole form, however, they can be used to make a tea that’s safe for consumption and essential oil for topical use or inhalation. In this article, we’ll be covering everything you need to know about this fragrant tree, from its history to its health benefits. Let’s get started.
The history of eucalyptus
Eucalyptus was first used by the Aborigines, the first people who lived in Australia. They reportedly chewed the roots for hydration and drank eucalyptus tea to treat fevers, eventually earning it the name Australian fever tea.
In the 1800s, eucalyptus oil started gaining notoriety in the medical world where it was used to clear mucus and promote easier breathing in conditions like bronchitis, flu, asthma, and coughs. As the years passed, it began being used in other ways as well. For instance, eucalyptus-infused cream was used to soothe tired, sore muscles and reduce pain and stiffness associated with arthritis.
What are the benefits of eucalyptus?
So, how do the age-old applications of eucalyptus hold up when put to the test with modern science? Very well, actually! Here are some of the top, science-backed benefits of eucalyptus.
- High in antioxidants
Eucalyptus leaves are packed with health-promoting terpenes, flavonoids, and other antioxidants, including cineole (also called eucalyptol), catechins, quercetin, isorhamnetin, luteolin, limolene, kaempferol, and phloretin. These antioxidants help fight oxidative stress (an imbalance of free radicals and antioxidants in the body), which can lead to cell and tissue damage.
- Antimicrobial properties
Toward the end of the 19th century, eucalyptus oil was used in most hospitals in England to clean urinary catheters due to its antimicrobial properties. Now, modern research is proving why this practice worked so well. Of the antioxidants in eucalyptus leaves, cineole is particularly valuable, as it’s been shown to have antimicrobial effects against many bacteria, including Mycobacterium tuberculosis and methicillin-resistant Staphylococcus aureus (MRSA). It’s also been shown to be effective against certain types of viruses and fungi, including candida.
- Relieves cold symptoms and respiratory problems
There’s a reason that eucalyptus is an ingredient in so many cold and cough products. Research shows that this menthol-like tree can decrease mucus and expand the bronchi and bronchioles of the lungs, leading to easier breathing, reduced sore throat pain, and reduced coughing. It also acts as a natural anti-inflammatory agent and may help improve asthma symptoms. The main ingredient responsible for these effects is cineole.
- Reduces pain
Because eucalyptus is highly anti-inflammatory, it should come as no surprise that it’s been shown to reduce pain levels. One three-day study involving people who had undergone knee replacement surgery found that inhaling eucalyptus oil for 30 minutes daily significantly decreased perceived pain levels.
- Promotes relaxation
Eucalyptus is widely believed to induce relaxation and ease stress. This effect is demonstrated in a few small studies. In one study, people experienced a significant reduction in pre-surgery anxiety after inhaling eucalyptus oil. Once again, this effect is due to cineole, which has been shown to have anti-anxiety properties.
How to use eucalyptus
Eucalyptus comes in a variety of forms, including tea, essential oil, and lotions. The form you choose largely depends on the issue you’re seeking help with. For example, if you’re looking to ease muscle tension, rubbing a eucalyptus-infused lotion on your muscles would be a good choice. If you’re looking to loosen phlegm and reduce cold symptoms, drinking eucalyptus tea or inhaling eucalyptus oil would be the best approach.

The bottom line
Eucalyptus is a calming tree that has been used medicinally for thousands of years. The leaves are brimming with beneficial compounds that have been shown to support respiratory health and other health issues.
It’s important to note that you should never eat the leaves themselves or ingest eucalyptus oil, as this can lead to negative side effects. Instead, brew a cup of eucalyptus leaf tea or inhale the scent of the oil to reap these incredible benefits.
