Lemon eucalyptus oil also has the potential to prevent and treat infectious diseases caused by viruses.

Researchers suggest that compounds found in eucalyptus essential oils may bind directly to virus proteins and prevent them from causing viral infections. More research is needed to fully understand how essential oils work. However, a significant number of studies support their effectiveness for certain symptoms and conditions.

Possible Side Effects of Lemon Eucalyptus Essential Oil

Experts consider essential oils to be generally safe. However, some may be dangerous for people who are pregnant or breastfeeding, or for people with existing medical conditions. Many essential oils are also toxic to pets, with cats in particular being particularly susceptible to their effects.

It is possible to have allergic reactions to essential oils. It is recommended to perform a patch test before using a new essential oil and always dilute it with a carrier oil before it comes into contact with the skin.

Essential oils high in phenols and aldehydes, which lemon eucalyptus contains, can cause side effects, including:
