Eucalyptus oil is an essential oil that is produced by distilling and drying the leaves of the eucalyptus tree. It can help relieve sinus pressure, congestion, and excessive mucous production. To lessen phlegm, people might think about inhaling a vapour that has eucalyptus oil as its primary component. The most frequent way to use eucalyptus oil is for patients to apply a lotion impregnated with the herb to their chests and breathe in the vapours. Try to get a lotion that has only natural components.

Patients may also opt to use a diffuser to inhale eucalyptus vapours by adding a few drops of the essential oil to it. A warm bath could also contain this oil. Any of these techniques will aid in loosening and thinning phlegm so that the body can remove it more quickly. Additionally, eucalyptus oil aids in relieving a congested nose, another issue that people with abundant phlegm frequently experience.
