Citrus medica, commonly known as the citron, is a large, yellow citrus fruit that is one of the original citrus species from which many other hybrids have been developed. It has a thick, bumpy rind and a small amount of pulp, making it less juicy than other citrus fruits. The citron is primarily grown in tropical and subtropical regions and is valued for its aromatic peel. Historically, Citrus medica has been used in various cultures for culinary, medicinal, and religious purposes. Its zest is often used in cooking and baking, while the fruit itself is sometimes used in traditional medicine. The citron tree is also notable for its ornamental value, featuring large, glossy leaves and fragrant flowers.
