Lime is a citrus fruit from the Rutaceae family, with Citrus latifolia (Persian lime, also known as Tahiti lime) being one of the most common varieties. Closely related to lemons and oranges, lime is valued for its tart flavor and bright aroma in beverages, savory dishes, and traditional remedies.

Low in calories and a good source of vitamin C, lime also contains citric acid, potassium, and flavonoids such as hesperidin and eriocitrin. These compounds may support immune function, digestion, cell protection, and hydration.
