Bay
Laurus nobilis
Laurus nobilis, commonly known as bay laurel, is a traditional plant used in Mediterranean and Middle Eastern cuisines. While its use in herbal medicine has not been extensively documented, studies have shown promising results. Research indicates that Laurus nobilis fruit extract may improve cardiac function and reduce oxidative stress in rats with pulmonary fibrosis-induced cardiopathy; however, the specific doses required for these effects are not clearly defined. The essential oil from bay laurel demonstrated strong antioxidant activity and showed potential antimicrobial properties when used as a CuO-ZnO hybrid nanocomplex. Yield and composition of the essential oil vary seasonally, with higher yields in summer and autumn, and 1,8-cineole being the predominant component. No major safety concerns or recorded drug interactions have been identified for Laurus nobilis.
