Background

• Coriander (Coriandrum sativum) is an annual herb in the Apiaceae family. The leaves are also referred to as "coriander leaves," "Chinese parsley," or "cilantro" (from Spanish) in the Americas. "Coriander" also refers to the spice produced from coriander seeds.
• Known for its strong flavor, cilantro is often used in Mexican, Asian, and Caribbean cooking. Recipes that specifically call for "fresh coriander" are referring to the leaves (cilantro). Both coriander and cilantro are commonly used in soups, salads, dressings, salsa, and chutney. The leaves are used in curry and guacamole.
• There is some evidence that Coriandrum sativum may improve vision, digestion, and blood sugar and cholesterol levels. Clinical studies have been done testing the use of cilantro to treat antibiotic-resistant bacterial infections and irritable bowel syndrome. It has also been used to treat mercury poisoning. However, better-designed clinical trials are needed before conclusions can be made regarding the effectiveness of cilantro for any condition.
• Chinese herbal medicine uses cilantro and coriander for measles, stomachache, and nausea. It is traditionally used as a home remedy for heat stroke, high blood sugar, and hemorrhoids. Some studies suggest that coriander juice mixed with turmeric powder or mint juice may be used as a treatment for acne.
• The flavor of cilantro has been described as a mix of parsley and citrus. Coriander is popular in Indian curries, spice mixtures, and tea infusions. Coriander oil is used for its antibacterial effects and as a natural fragrance in perfumes, soaps, and other cosmetics
