Coriander is one plant with two kitchen lives. The round, citrusy seed is dhanyaka in Sanskrit and dhania in Hindi, while the fresh green leaf is what most English speakers call cilantro. In Ayurveda the seed is the classical spice, and it carries a reputation as one of the cooling, balanced seasonings of the Indian kitchen.
This page covers both parts of the plant, sets out the traditional profile, gives a real kitchen section, and reports honestly what modern reference sources do and do not say. It is a guide to a food and spice with a traditional background. It is not a recommendation to use coriander for any health purpose.
What it is
Coriander is Coriandrum sativum, a soft, fragrant annual herb of the parsley family. People eat the leaves and stems fresh, and they dry the small tan fruits to use as the seed spice.
- Sanskrit: dhanyaka (the name is linked to dhanya, grain, and refers to the grain-like seeds).
- Hindi: dhania, for both seed and leaf; the leaf is sometimes called hara dhania.
- English: coriander seed, and cilantro or fresh coriander for the leaf (usage differs between countries).
Seed and leaf taste very different. The seed is warm, lemony and nutty. The leaf is bright and green, and a minority of people find it tastes soapy, which is a matter of taste and has no bearing on its safety.
The traditional view
Materia medica such as the Bhavaprakasha describes dhanyaka in detail, and later teachers have kept a fairly consistent picture, with the usual variations between schools.
- Taste (rasa): the commonly taught seed profile is sweet, bitter and astringent, with a little pungency in some accounts. See the six tastes for how tastes are understood.
- Potency (virya): generally cooling, which is the main reason coriander has a special place among spices for pitta.
- After-digestion effect (vipaka): sweet, in the standard teaching.
- Doshas: often described as balancing for all three, which is why teachers call it tridoshic, and as particularly calming to pitta. As with all such statements, this is traditional description and not a clinical measurement.
The tradition also notes that coriander is a spice that cools without being heavy, and cooks in hot climates and seasons have long favoured it. Teachers describe it as a seasoning that supports digestion without adding sharp heat, and a mild cooling spice drink made with coriander seeds is a popular household tradition. Those are folk and traditional uses. They are not claims of treatment.
To see where this fits in the year, the page on Grishma, the hot season, describes the kinds of cooling foods tradition prefers, though it does not single out coriander.
In the kitchen
Because the seed and the leaf behave differently, it helps to treat them as separate ingredients.
Seed
- Ground coriander is a base note in curry powders, garam masala, sambar powder and dry rubs. It thickens sauces slightly and rounds off hotter spices. In many Indian recipes it appears in larger quantity than cumin, with which it is usually paired.
- Toasted whole seeds release a deeper, sweeter scent. Crack them lightly in a mortar and add them to pickles, lentils, roasted vegetables, or use them in the French “a la grecque” way of cooking vegetables in a seasoned broth.
- Cooling infusions. A seed-water infusion (whole seeds steeped in water or briefly simmered) is used as a pleasant refreshing drink in hot weather. Treat it as a flavoured drink.
Leaf
- Chutney. Fresh leaf blended with green chilli, lemon juice, salt and sometimes coconut or mint gives the classic green chutney that goes with snacks, sandwiches and chaat.
- Garnish and finish. Stir the chopped leaves in at the end of cooking, because heat dulls their flavour quickly. Soups, dals, rice, raita and salads all benefit.
- Stems and roots. Do not discard the stems. They carry plenty of flavour, and cooks in Thai and Mexican kitchens grind stems and roots into pastes.
Storage tips. Keep whole seeds in an airtight jar away from light and grind small batches. Wash fresh leaves well, because they often carry grit and soil, shake dry, and store the bunch upright in a jar of water in the refrigerator or wrapped in a damp cloth. For ideas on pairing, the page on spices in the Ayurvedic kitchen is a good next step, and the discussion of qualities of foods helps explain why cooks balance cooling and heating ingredients in one dish.
What research says
Coriander has no dedicated page at NCCIH, MedlinePlus or LiverTox. The general picture for the Ayurvedic herbs is that research in people is limited and mostly small, while a lot of the claims repeated online come from laboratory or animal studies. We therefore make no statement that coriander has been proven to do anything, and the cooling and digestive reputation described above is tradition.
Safety and interactions
Our checks found that none of the three sources, NCCIH, MedlinePlus or LiverTox, covers coriander on its own page (MedlinePlus withdrew its herb pages in July 2025). So the following is a list of cautions drawn from the general guidance, and it should not be mistaken for a clearance of any kind.
- Food use is the baseline: seed, powder and fresh leaf as part of regular meals.
- Concentrated forms such as capsules, extracts, tinctures and essential oils sit outside what any of the sources covers. Get a doctor’s or pharmacist’s view before using them.
- Pregnancy and breastfeeding: there is no statement on coriander in the sources we checked, so go beyond food amounts only after speaking to your doctor.
- Children and infants: medical advice first for anything other than ordinary food.
- Prescribed medicines: NCCIH explains that most of the herb and drug interactions listed in current sources are theoretical, inferred from animals, cell tests or indirect reasoning, with warfarin, digoxin and cancer chemotherapy flagged as the drugs where caution counts most. Coriander is not named. If you take any regular medicine, particularly for blood clotting, diabetes, thyroid, blood pressure or immune function, tell your prescriber about any supplement.
- Liver and kidney problems: no coriander-specific statement exists in the sources, so ask for personal advice before using concentrated products.
- Operations: let the surgeon and anaesthetist know about all herbal products.
- Allergic reactions: reactions to herbs and spices in the parsley family can occur. Seek urgent help for swelling, hives or breathing difficulty.
- Contamination: NCCIH states that some Ayurvedic preparations may contain toxic amounts of lead, mercury or arsenic, and a 2015 survey reported elevated lead in many users of such products. Use dependable suppliers.

Frequently asked questions
↳ Is coriander cooling in Ayurveda?
Yes, the seed is traditionally described as cooling, with sweet, bitter and astringent tastes. That is why it is often linked with pitta and with hot weather. It is a traditional teaching and not a measured effect.
↳ Are dhania and coriander the same thing?
Yes. Dhania is the Hindi name for coriander, used for both the seed and the fresh green leaf. In English, the leaf is often called cilantro, particularly in North America.
↳ What is the difference between coriander seed and coriander leaf?
They come from the same plant but taste different. The seed is warm and citrusy, and it is used ground or toasted. The leaf is fresh and green, and it is used raw or added at the end of cooking.
↳ Is coriander water good for you?
It is a traditional household drink, but we found no source among those we checked that shows it helps any condition. Think of it as a refreshing flavoured water. If you have a health concern or take medicines, ask your doctor.
↳ Why does coriander taste like soap to some people?
Some people are sensitive to the aroma compounds in the fresh leaf, so it tastes soapy to them. This is about how they perceive flavour. It does not mean the herb is unsafe, and the seed usually tastes quite different.
