Cumin is the dried seed of the herb Cuminum cyminum, a member of the parsley family. The cumin plant grows to 30–50 cm (12–20 in) tall and is harvested by hand.

People usually buy cumin in the form of whole dried seeds or as ground powder. It is a typical ingredient in many spice blends, such as curry powder. Cumin is a staple spice in many food cultures, particularly Mexican, Indian, African, and Asian cuisine.
