Know About Ajwain Plant

6 Min Read

Ajwain (Trachyspermum ammi), commonly referred to as Bishop’s Weed or Carom in various regions, is an herbaceous annual belonging to the Apiaceae family, also referred to as the Umbelliferae family, and native to Eastern Mediterranean regions like Egypt, Iran, and India. Ajwain’s aromatic qualities have garnered much popularity throughout this aromatic herb’s wide usage, as both culinary and medicinal uses have grown widely over time.

Ajwain plants typically grow to heights of two feet, featuring feathery, pinnately compound leaves with feathery edges and producing small white or pink flowers that bloom in umbrella-shaped umbels. Their unique aroma and flavor come from their small, oval-shaped seeds with small ridges, which mature into oval brown seeds, providing Ajwain seeds with an aromatic peppery note in many dishes, breads, and snacks served across Indian cuisine.

Beyond its culinary uses, Ajwain also boasts an impressive legacy in traditional medicine. Renowned for its digestive properties and use in treating digestive issues, as well as its antimicrobial qualities and respiratory treatments, its cultivation typically involves well-drained soil in sunny locations with seeds harvested when they turn brown (usually within 120–150 days of planting) for harvesting and use in remedies for respiratory conditions. Overall, this herb stands as both a flavorful and versatile addition to many cultures and cuisines around the world.
