Ajwain is an annual herb known by several names, including ajowan and carom. It originated in the eastern Mediterranean region, possibly Egypt, and spread to India. Both its leaves and fruit pods are consumed by humans. The small, pale brown fruit pods resemble caraway and cumin in shape and have a bitter, pungent taste similar to anise and oregano. Ajwain seeds have long been used in Ayurvedic and Unani medicine to treat various ailments like flatulence and indigestion. In cooking, the seeds are commonly used in Indian, Pakistani, and Middle Eastern dishes and added at the end of cooking to preserve their fragrance and flavor.
