We are all familiar with the aroma of the cilantro (dhania), also called coriander. Sanskrit texts have mentioned the herb and it has been familiar as an important culinary and medicinal plant since early times. In the Bible, coriander is compared with manna. The Chinese associated it with immortality.


The cilantro plant is an annual herb with fine foliage. The leaves are finely divided into very narrow, lacy segments while the lower leaves are round and lobed. Flowers are small pink, pale blue, or white, borne in compound umbels. Small, round, ribbed seeds, which follow the flowers, have a sweet, spicy aroma with a peppery overtone and a mildly burning taste with just a hint of orange peel. The aroma and taste of the mature dried seeds are quite different to that of the leaves.

All over the world cilantro is used to garnish the yummy plates of various dishes. South Indian foods, especially the chutneys and rasam (soup), are insipid without coriander. The traditional kashayam (decoction) given by our grannies for cough cold and digestive disturbance invariably had cilantro as a main ingredient. Coriander seeds are known to have antibacterial properties and have been used in traditional medicine to relieve anxiety and insomnia. Dhania powder also helps to clear the body of lead, mercury, and aluminum. Dhania powder is also used as a flavoring agent in a number of pharmaceutical preparations, especially the digestive medicines.

India is a major coriander powder producing country, where Gujarat, Rajasthan, Andhra Pradesh, Tamilnadu, and Madhya Pradesh are main production areas. Globally Canada, Morocco, Pakistan, Bulgaria, and Romania are the major coriander producing countries.

Recent research studies on animals have confirmed healing effects like control of blood sugar, cholesterol and free radical production. When coriander was supplemented to the diet of diabetic mice, it helped stimulate their secretion of insulin and lowered their blood sugar. When given to rats, coriander reduced the amount of damaged fats in their cell membranes. And when given to rats fed a high-fat, high-cholesterol diet, coriander lowered levels of total and LDL that is the “bad” cholesterol, while actually increasing levels of HDL the “good” cholesterol.

Research also suggests that the volatile oils found in the leaves of cilantro may have antimicrobial properties. An antibacterial compound that may prove to be a safe, natural means of fighting salmonella, a frequent and sometimes deadly cause of food borne illness, suggests a study published in the June 2004 issue of the Journal of Agriculture and Food Chemistry.
