Synopsis

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

Bay leaf (Laurus nobilis) has been traditionally used in various cultures, particularly in Mediterranean and South Asian folk medicine, as a remedy for respiratory issues including nasal and chest congestion. The use typically involves inhalation of steam infused with bay leaves or the preparation of teas. The rationale is that the volatile oils (such as eugenol and cineole) present in bay leaf may exhibit mild expectorant and decongestant properties.

However, scientific evidence supporting bay leaf's efficacy for congestion is limited. A few in vitro and animal studies have demonstrated that certain compounds in bay leaf possess anti-inflammatory and antimicrobial activities, which may theoretically help with respiratory symptoms. Yet, there are no robust clinical trials or systematic reviews that confirm its effectiveness in relieving congestion in humans.

In summary, while bay leaf continues to be used traditionally for congestion, and its essential oils may provide subjective relief through aromatic inhalation, current scientific evidence is insufficient to strongly endorse its use for this purpose. Most of the support for bay leaf in treating congestion remains rooted in traditional practices rather than validated by high-quality research.
