About
What it is and where it shows up.
Bay leaves are the dried aromatic leaves of Laurus nobilis (bay laurel), widely used as a culinary spice to impart a subtle herbal, floral, and slightly woody flavour to soups, stews, sauces, and rice dishes. They are typically added whole during cooking and removed before consumption, or used in powdered form.
Safety summary
The regulatory and scientific consensus.
Bay leaves are considered safe at culinary use levels and are classified as GRAS by the US FDA with no established maximum use level or ADI. In large medicinal doses, the essential oil (containing 1,8-cineole, eugenol, and α-terpinyl acetate) may produce adverse effects including drowsiness or gastrointestinal irritation. Whole leaves should always be removed from food before serving, as they can pose a physical choking and mucosal laceration hazard if swallowed.
Regulatory landscape

Who should approach with care
Whose guidance would steer them away.
Pregnancy — Large medicinal or supplemental doses of bay leaf or its essential oil have reported uterotonic properties in some in-vitro studies; ordinary culinary use is generally considered safe.
Infants — Whole bay leaves should not be given to infants or very young children, as they can cause choking and physical laceration of mucosal surfaces of the digestive tract.
Children — Whole leaves must be removed from food before serving to children to eliminate any risk of choking or gastrointestinal injury from the stiff, fibrous leaf.
Diabetes — High-dose bay leaf supplements have demonstrated blood-glucose-lowering effects in clinical studies, and may potentiate antidiabetic medications causing hypoglycemia; culinary amounts are generally not of concern.
Other — Individuals with known allergy to plants in the Lauraceae family (e.g., avocado, cinnamon, camphor) may experience cross-reactive hypersensitivity reactions to bay leaf.
