What it is
Coriander seed is the dried fruit of Coriandrum sativum, an annual plant in the carrot family (Apiaceae). [1] The same plant gives us the fresh leaves called cilantro, which taste very different. See the Cilantro page for the leaf. The plant is native to the Mediterranean and West Asia. Large-fruited types grown in warm countries such as Morocco and India are mainly ground for the spice trade. [1]Flavor and aroma
Crushed seeds taste lemony and citrusy, and are also described as warm, nutty and a little spicy, with a note of orange. [1][4] The main aroma compound is linalool, about two thirds of the seed's volatile parts, with pinene also helping. [1] It is not sweet and not hot. Dry-toasting the seeds brings out more aroma and deepens the earthy side. Grinding them fresh gives a brighter, zestier taste. [1][3] Ground coriander loses its strength fairly quickly in storage. [1][4]How it is used in cooking
Whole seeds are toasted, crushed or ground. Ground seed is part of garam masala and many Indian curries, and it is often paired with cumin. [1]- India: curries, dals, sambar and garam masala. Cooks often fry whole seeds in hot oil or ghee at the start of a dish. [1][3]
- Middle East and North Africa: pickling spices, meat rubs, harira soup, tagine marinades and ras el hanout. [3]
- Mexico: chili pastes and moles, often with cumin. [3]
- Southeast Asia: spice pastes with lemongrass and galangal. [3]
- Europe: pickling, sausages, rye bread in place of caraway, some Belgian wheat beers and gin. [1][3]
- Snack: roasted seeds are eaten on their own in India. [1]
One cooking blog says to toast whole seeds in a dry pan for one to two minutes until they smell fragrant, and to use about half as much ground coriander as whole seed. [3] These are single-source tips. For a swap, Healthline names cumin (one to one), caraway, garam masala and curry powder, which is strong, so start with half. [4] Each changes the taste.
Normal food amounts
| Measure | Grams | Source |
|---|---|---|
| 1 teaspoon, seed | 1.8 g | USDA [12] |
| 1 tablespoon, seed | 5.0 g | USDA [12] |
| Typical recipe amount | Not found | We opened no source that states one |
What one teaspoon (1.8 g) of coriander seed provides, calculated from USDA values per 100 g:
| Nutrient | One teaspoon |
|---|---|
| Energy | about 5 kcal |
| Fiber | about 0.8 g |
| Calcium | about 13 mg |
| Magnesium | about 6 mg |
| Iron | about 0.3 mg |
| Potassium | about 23 mg |
The USDA SR Legacy data are from 2018 and real products vary. [12] We did not compare these numbers with official daily values, so we do not call coriander a "good source" of anything. A teaspoon is mostly flavor. Wikipedia lists fiber, calcium, iron and magnesium as present in the seeds, which fits the table. [1]
Buying, storing and preparing
- Forms: whole seeds, ground coriander, and the essential oil, which comes mostly from small-fruited types and is not a home-kitchen product. [1]
- Quality: the sources we read give no quality test. Whole seeds that smell lemony when crushed are a sensible sign; this is our advice, not a sourced rule.
- Shelf life: one cooking blog says whole seeds keep about a year and ground coriander is best used within three to four months. [3] Ground coriander loses strength quickly. [1][4]
- Storing: airtight, cool, dark and away from damp. [3]
- Grinding at home: a spice grinder or mortar works. Grind small amounts, as whole seeds hold their flavor longer. [3][4]
Health: what research says
Eating coriander seed in cooking is different from taking concentrated powders, syrups or extracts.Food amounts vs supplements
| In normal cooking | In supplements and extracts | |
|---|---|---|
| Typical amount | About 1.8 g per teaspoon (USDA); no usual recipe amount found [12] | One trial used 1,000 mg of seed powder a day for 6 weeks [5]. Another used 15 mL of syrup three times a day for a month [10] |
| What studies mostly used | We found no trial of coriander used as a seasoning | Seed powder, syrups, capsules (often mixed with other herbs), small trials from Iran [5][10][11] |
| What we can say about benefit | Nothing reliable | Small trials report benefits, but they are few and small [5][10][11] |
| Main safety limit | Allergy, which can be severe [8] | Allergy and skin reactions; the essential oil irritates skin [2][9] |
What the evidence shows
| Use | What the sources found | Strength of evidence | Form and population |
|---|---|---|---|
| Blood sugar and blood fats in type 2 diabetes | A 2025 trial found fasting glucose, insulin resistance, total and LDL cholesterol and triglycerides fell more with coriander than with placebo. The authors call it a possible complementary option. [5] | Promising but limited | Seed powder, 1,000 mg a day for 6 weeks; 40 adults aged 30 to 60 with type 2 diabetes [5] |
| Migraine | A 2016 trial found shorter, less severe and less frequent migraines with syrup than with placebo syrup. [10] | Promising but limited | Fruit syrup added to valproate; 68 people with migraine [10] |
| Functional dyspepsia | A 2024 trial found better symptoms and quality of life than placebo. [11] | Promising but limited | Capsule of a two-herb mix with Bunium persicum; 90 patients, so coriander alone was not tested [11] |
| Inflammation | A review of 24 preclinical papers found lower inflammation markers in most cell and animal studies, and no human studies. [6] | Lab or animal only | Cell and animal studies, various extracts [6] |
| Milk supply | LactMed says no valid clinical trials support this traditional use. [2] | Insufficient evidence | None identified [2] |
| Any effect of seasoning amounts | No study found | Insufficient evidence | Food amounts |

Official statements
- FDA (US): LactMed reports coriander is generally recognized as safe as a food. [2]
- EFSA (EU), 2023: in an opinion on coriander oil as animal feed, the panel saw no consumer concern at the proposed feed level and called the oil an irritant and a sensitiser. This is about feed, not kitchen use. [9]
- EMA, NCCIH, WHO/JECFA: we found no page for coriander seed that we could open, so we state nothing for them.

Safety note at a glance
Safety in more detail
- Medicines: the sources we read describe no drug interaction. Because the diabetes trial measured lower blood sugar, ask a pharmacist if you take diabetes medicine and plan to use supplements. [5]
- Pregnancy: the sources we read do not describe pregnancy risks for coriander in food. Ask your midwife or doctor about supplements.
- Breastfeeding: LactMed says coriander is generally recognized as safe as a food by FDA. It also reports one case of a nursing mother who drank a 10% water extract daily for a week to boost milk and later had an adrenal problem, and one woman with raised liver enzymes after a tea blend that contains coriander. These are single reports. [2]
- Children: a 2025 review lists coriander among spices implicated in allergic reactions in children, from mild mouth symptoms to anaphylaxis. [8]
- Allergy: coriander is an Apiaceae spice. A lab study found that cross-reacting allergens in anise, fennel, coriander and cumin matched birch and mugwort pollen allergy in 10 of 15 patients. [7] Wikipedia notes that, in a study of 589 suspected spice-allergy cases, about 32% of children and 23% of adults tested positive for coriander and other Apiaceae. [1] See Herbal Allergy and Cross-Reactivity.
- Liver and kidney: raised liver enzymes were reported once with a tea blend containing coriander. [2] The sources we read do not describe kidney problems.
- Surgery: the sources we read do not describe a surgery warning. Tell the team about any supplement.
- Quality and contamination: a 2021 review of crops watered with wastewater found harmful metals in coriander and lettuce. It covers the edible part and does not say whether that was leaf or seed. [13] Supplements vary, and LactMed notes labels and contents can differ. [2]
- Amounts that cause trouble: the sources we read give no harmful food amount. LactMed says allergic reactions, light sensitivity and contact dermatitis have been reported. [2] EFSA treats coriander essential oil as an irritant to skin, eyes and airways and a sensitiser. [9]
