Nigella sativa is a small flowering shrub with purple or white-tinged flowers that grows in Eastern Europe, the Middle East, and western Asia. While it may look unsuspecting, the shrub produces fruits that have tiny black seeds. These black seeds have been used in remedies for thousands of years. Archaeologists even found black seeds in King Tuts tomb, emphasizing their importance in history for healing and protection. They are also used in cooking to add flavor to breads, curries, and pickles. When eaten, the seeds have a bitter flavor that often compared to cumin or oregano.
