What is Koriandri and Why is it Also Called Coriander or Cilantro?
Koriandri refers to Coriandrum sativum, an annual herb in the Apiaceae family. The plant is unique in offering multiple usable parts: fresh leaves known as cilantro, dried seeds recognized as coriander, and aromatic roots employed in Southeast Asian cooking. Its dual identity in English coriander for seeds, cilantro for leaves often causes confusion, though botanically both come from the same plant.
Botanically, koriandri is a fast-growing, cool-season herb with delicate, lacy leaves resembling flat-leaf parsley. It produces small white umbels of flowers that mature into round, ridged seeds. While the leaves contain volatile aldehydes responsible for the fresh and sometimes “soapy” note, the seeds are dominated by warm, nutty compounds like linalool and pinene.
Regional language differences contribute to the cilantro vs. coriander divide. In North America, “cilantro” is reserved for fresh leaves, while “coriander” typically means the dried seeds. In the UK and much of Asia, “coriander” refers to both forms, clarified by context. In South Asia, it is commonly called “dhania,” while in China it is nicknamed “Chinese parsley.”
What is the Botanical Classification of Koriandri?
Koriandri (Coriandrum sativum) belongs to the Apiaceae family, which also includes parsley, fennel, and dill. It is an annual herb with feathery leaves, small white umbels of flowers, and round ribbed seeds. The plant is unique because all its parts leaves, seeds, and roots are used in cooking.
Why Do Some People Call It Cilantro While Others Say Coriander?
In North America, the fresh leaves are called cilantro and the dried seeds are called coriander. In the UK, South Asia, and most of the world, both leaves and seeds are called coriander. Locally, it is also known as dhania or Chinese parsley.
How Does Koriandri Taste and Why Do Some People Say It Tastes Like Soap?
Koriandri’s taste is complex, combining citrusy freshness, herbal warmth, and nutty undertones. The leaves are dominated by volatile aldehydes such as (E)-2-alkenals and (E)-2-alkenols, which give a sharp, green flavor. Essential oils like linalool contribute floral and citrus notes, balancing the sharper tones.
The infamous “soapy” perception of cilantro is linked to a genetic factor. Variants of the OR6A2 olfactory receptor gene make certain individuals hypersensitive to aldehydes present in koriandri leaves. Instead of a bright citrus aroma, these people experience a soapy or metallic taste, explaining the global divide between coriander lovers and haters.
This taste variation has cultural implications. In regions like Mexico, India, and Thailand, koriandri is a cornerstone ingredient embraced by most palates. In Northern Europe, however, dislike is more common, and recipes often substitute parsley, chervil, or culantro. Understanding the genetic basis allows chefs and home cooks to adapt recipes for diverse audiences.
What Compounds Contribute to Its Scent and Flavor?
The fresh leaves contain aldehydes that give a citrusy, sharp, and sometimes soapy flavor. The seeds are rich in linalool and pinene, which create a warm, nutty, and slightly sweet aroma. Roots carry a deeper, earthy fragrance used in curry pastes.
Which Genetic Factors Influence Coriander Perception?
The OR6A2 gene affects how people perceive koriandri. Some individuals are more sensitive to aldehydes in the leaves and experience a strong soapy or metallic taste, while others perceive it as citrusy and refreshing.
What Are the Nutritional and Health Benefits of Koriandri?
Koriandri is more than a flavoring agent it is nutrient-dense and phytochemically rich. Fresh leaves provide vitamins A, C, and K, alongside minerals such as potassium, calcium, iron, and magnesium. Coriander seeds are an excellent source of dietary fiber, manganese, and essential oils with therapeutic potential.
Scientific studies suggest koriandri supports digestion, reduces bloating, and acts as a carminative. Antioxidants like quercetin and phenolic acids help neutralize free radicals, potentially lowering oxidative stress. Animal and human trials indicate coriander seeds may help regulate blood sugar and cholesterol, making them relevant for metabolic health management.
While koriandri is generally safe, allergies are reported, particularly among those sensitive to other Apiaceae plants such as celery and fennel. Excessive intake of coriander extracts may cause mild gastrointestinal discomfort. Pregnant and breastfeeding women should avoid high-dose supplementation unless guided by a healthcare professional.

How Do You Grow, Harvest, and Store Koriandri at Home?
Koriandri thrives in well-draining soil, full sun, and moderate watering. It prefers cool temperatures, making spring and autumn ideal for sowing. Seeds should be planted directly into soil, as transplantation may cause bolting. Thin seedlings to encourage airflow and steady growth.
Leaves can be harvested once plants reach 4–6 inches. Frequent cutting encourages regrowth, but eventually plants will bolt and set seed. Coriander seeds are ready when they turn brown and dry on the stalks. Roots can be harvested from mature plants before seeding.
Storing koriandri requires attention to aroma preservation. Fresh leaves should be refrigerated in damp paper towels or placed in jars of water, lasting up to a week. Seeds should be dried fully and stored in airtight containers away from light. Ground coriander loses potency quickly; for maximum flavor, grind seeds just before use.
