Rating (out of 5): 2

Citrus oils, such as those derived from orange, lemon, and grapefruit, have a long history of use in traditional medicine, particularly in aromatherapy. They have often been employed to alleviate respiratory discomfort and support relief from congestion, based largely on their invigorating scent and perceived ability to clear the airways. Historically, these essential oils were inhaled via steam or diffusers to help "open up" the chest or sinuses, though these uses are rooted more in anecdotal practice than in robust scientific study.

The main components of citrus oils—such as limonene, linalool, and citral—are known for their pleasant aroma and mild antimicrobial properties. However, unlike oils such as eucalyptus or menthol, citrus oils do not directly act as decongestants or mucolytics. Scientific studies specifically evaluating the effect of citrus oils on congestion are limited and inconclusive. While some small studies and animal models suggest a mild anti-inflammatory or mood-lifting effect, there is not enough high-quality evidence to support a direct decongestant action.

In summary, the use of citrus oil for treating congestion is primarily based on tradition, with some support from its general uplifting and refreshing qualities. Its direct effectiveness for congestion remains unproven in clinical research, so users should temper expectations and consider evidence-based alternatives for significant respiratory symptoms.
