Coriander has been cultivated and used for over three millennia, with its presence recorded in some of the earliest civilizations. Archaeological evidence suggests that coriander seeds were placed in the tombs of ancient Egyptians as early as 1500 BCE not only as a spice but also as a medicinal and spiritual offering. The Greeks and Romans also recognized its value; Roman soldiers carried coriander seeds to flavor bread and wine while Greek physicians used it for digestive issues and respiratory problems.

Extraction Process of Coriander Seed Oil
