Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Aromatherapy, which utilizes essential oils and aromatic plant extracts, has a long history of traditional use for alleviating congestion. Historically, various cultures have used inhalation of steam infused with aromatic substances—such as eucalyptus, peppermint, or menthol—to help relieve symptoms of nasal and chest congestion. These practices are rooted in folk medicine and have been passed down through generations. The proposed mechanism is that certain volatile oils may help open the nasal passages or promote a feeling of easier breathing, primarily due to the cooling or soothing sensation they produce.

While there is some scientific interest and limited research into the potential decongestant effects of specific essential oils (notably eucalyptus and menthol), robust clinical evidence remains scarce. Most studies are small, of low quality, or focus on subjective symptoms rather than objective improvement in airflow. Reviews of available research generally find insufficient evidence to support widespread clinical use, but acknowledge that some individuals may perceive symptomatic relief. Thus, the use of aroma for congestion is primarily justified by traditional practice and anecdotal experiences rather than strong scientific validation.
