eucalyptus
Meaning of eucalyptus: Eucalyptus oil is a plant derived ingredient added in small amounts to cough drops and chest rubs, though the concentrated oil is toxic if swallowed.
Definition of eucalyptus
Eucalyptus is a type of evergreen tree, a member of the myrtle family, native to Australia and now grown in many other regions. Oil extracted from its leaves is rich in a compound called eucalyptol, also known as cineole, which gives the oil its characteristic cooling, minty aroma.
In small, diluted amounts, eucalyptus oil is added to products such as mouthwash, cough drops, and topical chest rubs, where it is used to soothe a sore throat or ease the sensation of a stuffy nose. It has also been used in various traditional practices for a wider range of purposes, though evidence supporting many of these broader uses is limited.
Eucalyptus oil in its concentrated, undiluted form is significantly more potent than the small amounts used in over the counter products, and swallowing even a small quantity of the pure oil can cause serious toxicity, particularly in young children, a risk distinct from the safety of diluted eucalyptus containing products.
Used in a sentence
The patient reported using a eucalyptus containing chest rub to help with cough symptoms.
Good to know
Diluted eucalyptus oil used in over the counter products carries a very different safety profile from the concentrated essential oil, which can cause serious toxicity if swallowed even in small amounts.
