Synopsis

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

Sweet Bay (Laurus nobilis), also known as bay laurel, has been used traditionally in various cultures for respiratory ailments, including sinus infections. The use of bay leaves in folk medicine often involves inhaling steam from boiling the leaves or using them in poultices, with the belief that their aromatic compounds help clear nasal passages and reduce congestion. Essential oils derived from Sweet Bay contain compounds such as eugenol, cineole (eucalyptol), and linalool, which have mild antimicrobial and anti-inflammatory properties. However, the direct application of Sweet Bay for sinus infection lacks robust clinical studies. Existing evidence is mostly anecdotal or based on the known properties of its volatile oils, some of which show antimicrobial activity in vitro. No high-quality human clinical trials directly support its efficacy for sinus infections. Most recommendations are rooted in traditional herbal practice rather than scientific validation. Therefore, while there is a historical precedent for using Sweet Bay as a supportive treatment for sinus infections, scientific evidence remains limited, and its use should be considered complementary rather than primary or evidence-based therapy.
