Lemon eucalyptus


Lemon eucalyptus (Corymbia citriodora) is a tree. Oil from its leaves are used as medicine.

Lemon eucalyptus contains chemicals that repel mosquitoes and kill fungus.

People use lemon eucalyptus oil to repel mosquitos. It is also used for joint pain, osteoarthritis, to repel ticks, and for many other conditions, but there is no good scientific evidence to support these uses.

Don't confuse lemon eucalyptus with similarly named eucalyptus, lemon, lemon balm, lemon verbena, or lemongrass. These are not the same.
When taken by mouth: There isn't enough reliable information to know if lemon eucalyptus is safe or what the side effects might be.

When applied to the skin: Lemon eucalyptus oil is likely safe when used short-term. It's generally well-tolerated, but some people might have a mild skin reaction to the oil.
