Cumin is the dried seed of the herb Cuminum cyminum, a member of the parsley family. The cumin plant grows to 30â50 cm tall and is harvested by hand. It is an annual herbaceous plant, with a slender, glabrous, branched stem that is 20â30 cm tall and has a diameter of 3â5 cm. Each branch has two to three subbranches. All the branches attain the same height, so the plant has a uniform canopy. The stem is coloured grey or dark green. The leaves are 5â10 cm long, pinnate or bipinnate, with thread-like leaflets. The flowers are small, white or pink, and borne in umbels. Each umbel has five to seven umbellets. The fruit is a lateral fusiform or ovoid achene 4â5 mm long, containing two mericarps with a single seed. Cumin seeds have eight ridges with oil canals. They resemble caraway seeds, being oblong in shape, longitudinally ridged, and yellow-brown in colour, like other members of the family Apiaceae (Umbelliferae) such as caraway, parsley, and dill.
