Bayleaf (Laurus nobilis) has a long history of use in traditional medicine systems, particularly in Mediterranean and South Asian cultures. Historically, bayleaf has been used as a home remedy for respiratory issues such as bronchial congestion, coughs, and colds. Its essential oil contains compounds like eucalyptol (1,8-cineole), which is also found in eucalyptus and is known for its expectorant properties. In folk medicine, bayleaf-infused steam or topical balms using bayleaf oil have been applied to the chest to help clear mucus and ease breathing. However, the scientific evidence supporting these uses is limited. While some laboratory studies have noted antimicrobial and mild anti-inflammatory activity for bayleaf extracts, there is a lack of well-controlled clinical studies specifically evaluating its effects on bronchial congestion in humans. Therefore, its use for this purpose is justified mainly by tradition and anecdotal reports rather than robust scientific validation. Caution is advised with essential oil use, as direct inhalation or application can cause irritation in some individuals. Overall, bayleaf’s use for bronchial congestion remains rooted in traditional practice, with minimal scientific endorsement.
