Bay leaf is primarily used to flavor foods, and it is used by chefs of ethnic cuisines, from Italian to Thai. It is also frequently used in salt-free seasonings.

Bay leaf is thought to be useful for gastric ulcers, high blood sugar, migraines, and infections. Bay leaves and berries have been used for their astringent, diaphoretic (promotes sweating), carminative (promotes digestion), digestive, and stomachic (tones and strengthens the stomach) properties. In the Middle Ages bay leaf was believed to induce abortions. Traditionally, the berries of the bay tree were used to treat furuncles. The leaf essential oil of Laurus nobilis has been used as an antiepileptic remedy in Iranian traditional medicine.

Currently, there is not enough scientific evidence to draw any firm conclusions about the medicinal safety, effectiveness or dosing of bay leaf.
