Bold, antiseptic & a great insect repellent Lemon-scented eucalyptus essential oil is derived from the leaves of the lemon-scented eucalyptus tree, also known as Eucalyptus citriodora. This essential oil is known for its fresh, citrusy aroma, and is believed to have a wide range of therapeutic benefits. One of the most well-known benefits of lemon-scented eucalyptus essential oil is its ability to repel insects, including mosquitoes and ticks. It can also be used to soothe respiratory issues such as coughs, colds, and asthma, due to its anti-inflammatory and decongestant properties. Whilst it has many amazing qualities, it also has a very strong aroma and we do not recommend to diffuse it in a childs room at night.
