Oral health 

Dental cavities are common throughout the population as they are caused by different factors such as bacteria. According to the scientific journal Phytomedicine Plus (2021), eucalyptus has antimicrobial properties, that is, it can fight and eliminate bacteria, and can therefore be used effectively to treat dental cavities.

Analgesic property 

Eucalyptus is said to have analgesic properties: different studies have been conducted in this area. For example, a research study evaluated pain reduction in 10 people who had undergone surgery. The test consisted in inhaling eucalyptus oil for 30 minutes for 3 days; the result was positive as the patient’s pain was reduced. It has also been shown in other studies that when applied topically it can reduce mild muscle pain (Phytomedicine Plus, 2021).


It is worth noting that the use of eucalyptus in different fields such as medicine is still under considerable study, being a plant with numerous potential benefits and an innovative strategy.

Where did eucalyptus originate? 

The eucalyptus tree is said to have originated in Australia.

How is eucalyptus cultivated? 

The eucalyptus tree is grown to reforest different areas because it is fast growing, in fact, it can grow up to 3 meters in just 1 year. Read on to learn about all the characteristics of the cultivation of this plant.


Eucalyptus can grow in a diversity of climates, but tropical to temperate areas are preferred. We are talking about optimum temperatures of 18 to 25 °C; it tolerates at least -5 °C, as it is usually sensitive to frost.


The eucalyptus tree tolerates different types of soils, from dry to more humid, but it is worth noting that humid soils with good drainage are preferred. In addition, this tree consumes high amounts of water, it is said that they can consume up to 50 liters of water per day in high summer temperatures.

Curious fact:

Although it is believed that eucalyptus can damage the soil, different studies have proven this to be false. Planting these trees has no negative effects either on the soil or on productivity.

Propagation of eucalyptus 

This tree can be propagated both by seeds and cuttings, although it is usually cultivated through seeds, at temperatures of 13 to 18 °C for its correct germination. The plants are moved to the field intended for cultivation when they are 20 to 30 cm high, at approximately 12 to 14 weeks.

Harvest and post-harvest 

Normally, the foliage of the tree is harvested when the branches reach at least 50 cm in length. They are then hydrated and immersed in clean water for at least two hours at a temperature of about 5 °C (41 °F). A curious fact is that harvesting the eucalyptus foliage rejuvenates the plant and stimulates the germination of new shoots.
