Direct answer: Coriander seed (芫荽籽, yánsuī zǐ) is the dried fruit of Coriandrum sativum, an annual herb of the carrot family (Apiaceae) native to the Mediterranean and western Asia. It is a warm, citrusy spice with a woody, faintly floral undertone, used in Chinese incense as a fresh spice accent. It is the seed of the same plant as cilantro (芫荽), but seed and leaf are very different aromatics.
Key facts
| Chinese | 芫荽籽 (yánsuī zǐ); the leaf herb = 芫荽 / 香菜 |
| Botanical source | Coriandrum sativum (family Apiaceae) — the dried fruit (“seed”) |
| What it is | A dried spice fruit, not a wood or resin |
| Aroma | Citrus, woody, spicy, faintly floral |
| Traditional role | Culinary spice, materia medica, fresh incense accent |
Aroma profile
Direct answer: Coriander seed is warm and citrusy, with a woody, slightly spicy, faintly floral character that is completely different from the fresh, soapy-tasting leaf. The seed’s aroma comes largely from the essential oil linalool, which gives it a clean, sweet-woody, citrusy lift. It is a fresh spice accent rather than a base note.
Coriander seed is warm and citrusy, with a woody, slightly spicy, faintly floral character that is completely different from the fresh, soapy-tasting leaf. The seed’s aroma comes largely from the essential oil linalool, which gives it a clean, sweet-woody, citrusy lift. It is a fresh spice accent rather than a base note — it brightens heavier blends in the way that citrus and fennel do.
The seed-vs-leaf contrast is the defining fact: the seed is warm, citrusy, and woody, driven by linalool, while the leaf is fresh, green, and polarizing (a soapy taste many people perceive). This is a rare case where one plant yields two aromatics that are effectively opposites — the seed a sweet-citrus spice, the leaf a sharp green herb. For any aromatic use, this distinction is the first thing to get right.
Botanical source and origin
Direct answer: Coriandrum sativum is an annual herb of the carrot family (Apiaceae), native to the Mediterranean and western Asia, now grown worldwide. The same plant yields two distinct aromatics: the fresh leaf (cilantro, 芫荽/香菜) and the dried fruit, coriander seed. The seed is the part used in incense and most spice blends.
Coriandrum sativum is an annual herb of the carrot family (Apiaceae), native to the Mediterranean and western Asia, now grown worldwide. The same plant yields two distinct aromatics: the fresh leaf — cilantro in English, 芫荽 or 香菜 in Chinese — and the dried fruit, coriander seed. The seed is the part used in incense and most spice blends; its warm, citrusy character is entirely unlike the leaf. Flora of China records the species as cultivated throughout China, noting that the stem and leaves are used as a culinary herb (coriander, cilantro) while the fruit is used as a spice — a single entry that captures the two-part identity of the plant.
A naming caution: coriander seed (芫荽籽) and the leaf herb cilantro (芫荽 / 香菜) come from the same plant, Coriandrum sativum, but are different aromatics. The seed is warm, citrusy, and woody; the leaf is fresh, green, and polarizing. In incense it is the seed that is used.
Chinese name and terminology
Direct answer: 芫荽籽 (yánsuī zǐ) means “coriander seed” — 芫荽 for the coriander plant, 籽 for “seed.” The older name 胡荽 (húsuī) carries the 胡 foreign-origin prefix, marking coriander as an imported aromatic. The leaf herb is separately named 香菜 (“fragrant vegetable”), reflecting its fresh culinary use.
The name 芫荽籽 is a two-part label: 芫荽 (the coriander plant) + 籽 (seed), explicitly naming the seed as distinct from the leaf. The older name 胡荽 carries the 胡 foreign-origin prefix — the same marker in pepper (胡椒) and fenugreek (葫芦巴) — recording coriander’s arrival as a western import. The leaf herb, meanwhile, is commonly called 香菜 (“fragrant vegetable”) in everyday use. This name structure is itself a disambiguation: 芫荽籽 names the seed, 香菜/芫荽 names the leaf, and 胡荽 records the plant’s imported origin.
Why is it used in incense?
Direct answer: Coriander seed appears as a fresh, citrusy spice accent in some blended incense (合香) formulas, alongside fennel and citrus peels, rather than as a classical defining material. Its linalool-driven, warm-citrus character brightens heavier blends, and it is the seed — not the leaf — that serves this role.
Coriander seed’s incense role is a fresh spice accent: it appears in some 合香 blends alongside fennel and citrus peels, where its warm, citrusy, linalool-driven character brightens and lifts heavier compositions. It is a supporting note, not a lead — a clean, sweet-woody citrus lift beneath the resins and woods. The critical point is that this role belongs to the seed, not the leaf: the seed’s warm-citrus spice is the aromatic contribution, while the leaf’s fresh, green, polarizing character has no place in an incense blend. The two are not interchangeable.
How is it processed?
Direct answer: Coriander seed is produced by harvesting the ripe fruit and drying it whole; the dried, round seed-fruit is the traded form, used whole or ground. Drying concentrates the warm, citrusy, linalool character, and no extraction is required — though coriander essential oil can be steam-distilled from the seed.
The ripe fruits are harvested and dried whole, producing the round, ridged seed-fruit that is the traded form. Drying concentrates the warm, citrusy, linalool-driven character, and the material is used whole or ground like any seed spice. For essential-oil use, the seed is steam-distilled, but the spice itself needs no processing beyond drying. The whole seed retains its aroma far longer than pre-ground powder — a practical point, since the seed’s linalool-driven note degrades faster once ground.
What determines quality?
Direct answer: Coriander seed quality turns on the freshness and intensity of its citrusy, linalool aroma. Good seed is round, dry, and strongly warm-citrusy on crushing, without a stale or musty note; the whole seed retains its aroma far longer than ground powder.
The practical checks are: aroma intensity (a strong, clean, warm-citrusy note on crushing — the linalool character — not a stale or musty edge), freshness (round, dry, sound seed rather than shriveled or old material), and form (whole seed retains its aroma far longer than ground powder). The crush test is the standard quality check, and whole seed is the reference form precisely because the volatile linalool escapes quickly once ground.
Common forms
Direct answer: Coriander is traded as whole seed and as ground powder; the whole seed is the reference form, retaining its linalool aroma far longer than the ground spice. The leaf herb (cilantro) is a separate fresh product, not the seed’s equivalent.
| Form | Typical use |
|---|---|
| Whole seed | Culinary spice; the reference form, best shelf life |
| Ground powder | Blending and dosing; loses aroma faster |
| Fresh leaf (cilantro) | A separate culinary herb, not the seed’s aromatic equivalent |
The whole seed is the reference form; the powder is a convenience form, and the fresh leaf is a different product entirely — the same plant’s other aromatic.
In Chinese tradition
- Culinary spice: coriander seed is a warm, citrusy spice used in cooking and spice blends.
- Materia medica: 芫荽 and 胡荽 (older name) are recorded in traditional Chinese medicine (本草綱目, 菜部) as aromatics. This is traditional materia-medica language, not modern clinical evidence.
- Incense context: coriander seed appears as a fresh spice accent in some 合香 blends, alongside fennel and citrus peels, rather than as a classical defining material.
Traditional use vs modern evidence
Direct answer: The culinary role of coriander seed is well documented, and its linalool chemistry is established. Medicinal uses are traditional, not established clinical fact, and no medical claim is made. The page’s core factual point is the seed-vs-leaf distinction — two aromatics from one plant.
- Traditional Use — coriander seed as a culinary spice and a fresh incense accent; the leaf herb as a culinary herb.
- Historical Record — 芫荽 / 胡荽 recorded as a culinary herb and materia-medica aromatic in the 本草綱目 菜部.
- Scientific Evidence — the botanical identity (Coriandrum sativum, Apiaceae) is established, and linalool is the established compound behind the seed’s citrusy-woody note. No clinical or medical efficacy claims are presented.
The culinary role is well documented. Medicinal uses are traditional, not established clinical fact, and we make no medical claims. The documented, non-medical facts are botanical identity, the seed-vs-leaf distinction, and the fresh, citrusy aromatic use.
Quality notes
Practical points:
- Whole coriander seed should be round, dry, and fragrant with a warm, citrusy, slightly floral aroma; ground seed loses scent faster.
- Distinguish the seed (芫荽籽, warm and citrusy) from the leaf herb (芫荽 / 香菜, fresh and green) — different aromatics from the same plant.
- In incense, coriander seed is a fresh spice accent, usually blended, not burned alone.
- Specify “seed” explicitly — a label saying only “coriander” does not separate the seed from the leaf.
Coriander seed vs the leaf (cilantro): one plant, two aromatics
Direct answer: Coriander seed and cilantro leaf come from the same plant, Coriandrum sativum, but are opposite aromatics. The seed is warm, citrusy, and woody (linalool); the leaf is fresh, green, and polarizing (a soapy taste to many). They are not interchangeable in any aromatic use.
| Coriander seed (芫荽籽) | Cilantro leaf (芫荽/香菜) | |
|---|---|---|
| Plant part | Dried fruit | Fresh leaf |
| Character | Warm, citrusy, woody | Fresh, green, polarizing |
| Key compound | Linalool | Aldehydes (soapy note) |
| Incense use | Fresh spice accent | None (not used) |
The distinction is the page’s core: one plant, two aromatics, and only the seed serves the incense role. See fennel, orange-peel, and the material comparison matrix.
Summary
Coriander seed (芫荽籽) is the dried fruit of Coriandrum sativum, an annual carrot-family (Apiaceae) herb native to the Mediterranean and western Asia. It is a warm, citrusy, woody spice driven by linalool — the seed of the same plant as cilantro (芫荽/香菜), but a completely different aromatic from the fresh, green leaf. It is a culinary spice, a recorded materia-medica aromatic, and a fresh spice accent in some 合香 blends, and the key sourcing point is the seed-vs-leaf distinction.
FAQ
What is coriander seed? The dried fruit of Coriandrum sativum, an annual herb of the carrot family (Apiaceae) native to the Mediterranean and western Asia. It is a warm, citrusy spice with a woody, faintly floral undertone, used in cooking, spice blends, and as a fresh accent in some incense. It is the seed of the same plant as the leaf herb cilantro.
Are coriander seed and cilantro the same thing? They come from the same plant, Coriandrum sativum, but are different aromatics. The seed (芫荽籽) is warm, citrusy, woody, and faintly floral; the leaf (cilantro, 芫荽 / 香菜) is fresh, green, and strongly flavored. In incense and most spice blends, it is the seed that is used. They are not interchangeable in aroma.
What does coriander seed smell like? Warm and citrusy, with a woody, slightly spicy, faintly floral character that comes largely from the essential oil linalool. It is a fresh spice accent — it brightens heavier blends in the way that citrus and fennel do — rather than a base note. The seed’s aroma is entirely unlike the fresh, green scent of the coriander leaf.
What is coriander (芫荽) in Chinese tradition? 芫荽 (also 胡荽 in older texts) is the coriander plant, recorded as a culinary herb and a materia-medica aromatic in the 本草綱目 菜部. The seed (芫荽籽) is the part used as a spice, and it appears as a fresh accent in some blended incense (合香) formulas alongside fennel and citrus peels.
How should coriander seed be stored for quality? Whole, rather than ground. Whole coriander seed is round, dry, and fragrant with a warm, citrusy, slightly floral aroma, and it retains its scent far longer than pre-ground powder. The strength of the aroma when the seed is freshly crushed is the main quality indicator, and in incense it is a fresh spice accent used in blends.
What does the 胡 in coriander (胡荽) mean? It is the classical foreign-origin prefix, the same 胡 in pepper (胡椒) and fenugreek (葫芦巴), marking coriander as a western import. The modern 芫荽籽 adds the 籽 “seed” suffix to separate the seed from the leaf herb (芫荽/香菜).
