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 citrus varieties 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 often used for its aromatic peel and is valued in culinary and medicinal applications. Historically, Citrus medica has been cultivated in regions like the Mediterranean and Asia for thousands of years. It is significant in various cultures, often associated with religious and ceremonial practices. The fruit is also used in traditional medicine and as a flavoring agent in foods and beverages.
