You may have heard about lemon essential oil and lemon eucalyptus oil—but what about lemon eucalyptus oil? If you live in an area with tons of mosquitos, you’re probably familiar with the refined version known as oil of lemon eucalyptus. It made waves when researchers found that it was just as effective as other bug sprays with harsh chemicals such as DEET. What you may not know is that this essential oil has loads of other benefits for your health.
Lemon eucalyptus essential oil helps to keep you healthy and happy by freshening the air and helping fight off the common cold. It can be used topically or during aromatherapy. It boasts a citrusy yet woodsy scent that is a pleasure to inhale.
What is Lemon Eucalyptus Essential Oil?
Lemon eucalyptus oil is extracted from the leaves and twigs of the lemon-scented gum eucalyptus plant. This plant is also known by the botanical names Eucalyptus citriodora and Corymbia citriodora. This eucalyptus tree is also commonly known as lemon eucalyptus and is part of the Myrtaceae family.
Naturalists did not recognize the Corymbia genus until the mid-1990’s. Prior to that, these trees were simply classified as eucalyptus trees. Today, the lemon eucalyptus distinction refers to around 113 species,—most of which are found in Australia. The oil is also sometimes referred to as oil of lemon eucalyptus rather than eucalyptus essential oil. This helps to identify the exact eucalyptus species and process used to extract the oil.
The lemon eucalyptus tree features a white to coppery bark and leaves that smell like lemons. These trees grow best in forests and woodlands. They grow best in acidic, loamy soil. Lemon eucalyptus trees are native to the Darling Range in Western Australia. Today, these trees are also cultivated in other parts of Australia including New South Wales, Victoria and Southern Australia. There are also large oil producing forests in China, India and Brazil.
Twigs and leaves are the plant parts used to make this oil. The oil is removed from the tree through an extraction method known as steam distillation. The active ingredient in pure lemon eucalyptus oil is citronella, which makes up 80% of the oil’s composition.
Oil of Lemon Eucalyptus vs Lemon Eucalyptus Essential Oil
There are two types of lemon eucalyptus oil: refined oils and unrefined oils. Refined oils are used in bug sprays while unrefined oils are used in fragrances. Refined oils contain high amounts of PMD while unrefined oils are typically higher in citronella content.
Refined oils are known in the United States as oil of lemon eucalyptus and in Europe as PMD rich botanic oil. These refined oils are typically used in bug repellents. In fact, the EPA has registered 10 bug repellent products that use oil of lemon eucalyptus. The leaves are plucked from the eucalyptus tree and aged to create isomers known as p-Menthane-3,8-diol, known as PMD. This ingredient can comprise close to 98 percent of refined lemon eucalyptus oil.
Unrefined oils are more commonly used in perfumes and contain only trace amounts of PMD. Lemon eucalyptus leaves are plucked and immediately steam distilled. In essence, lemon eucalyptus oil is higher in citronella while oil of lemon eucalyptus is higher in PMD. Both types of eucalyptus oil boast significant health benefits, but for bug sprays, oil of lemon eucalyptus is preferred.
Lemon eucalyptus oil has a pale color and thin consistency. The aroma is sweet and lemony with a woodsy finish. This oil blends well with other woodsy scents including tea tree oil, frankincense and clove oil.

Oil of lemon eucalyptus became popular after it was cited as an effective mosquito repellent. Studies have shown that lemon eucalyptus is almost as effective as repellents that contain DEET.

Lemon eucalyptus oil is a safe alternative that still boasts efficacy without negative side effects for your health.
