Coriander is a spice produced from the round, tan-colored seeds of the coriander plant (Coriandrumsativum), which is a member of the parsley family. The word coriander can be used to describe the entire plant: leaves, stems, seeds, and all. But when speaking of coriander, most people are referring to the spice produced from the seeds of the plant. The leaves of the plant are commonly called cilantro, which comes from the Spanish word for coriander, or Chinese parsley. Coriander roots also appear in culinary use as a pungent addition to Thai curries. Coriander grows as a native plant around the world, including Europe, Asia, Africa and in the Americas.
Coriander has been used in traditional medicine for stomach ailments. It is sometimes included in teas that are designed to help relieve constipation. Research is being done to see if it has any verified health benefits for conditions such as diabetes. Fresh cilantro greens provide fiber and phytonutrients, while the seeds have a small amount of calcium, potassium, magnesium, and phosphorus.
