Coriander Overview

It is native to the Mediterranean region and is widely cultivated in many parts of the world. When used as medicine, coriander is most often used for gastrointestinal problems, including dyspepsia, nausea, diarrhea, flatulence, constipation, irritable bowel syndrome (IBS), and to stimulate the appetite.
