You’re standing in the produce aisle, clutching a recipe that calls for a bunch of fresh coriander, but all you see are rows of what looks like flat-leaf parsley and something labeled "cilantro." It’s frustrating. Honestly, it's one of those weird culinary glitches that confuses even decent home cooks. If you’ve ever wondered why your British cookbook asks for coriander leaves while your local Tex-Mex spot piles on the cilantro, you're just bumping into a linguistic regional divide. Basically, they are the exact same plant, Coriandrum sativum. But depending on where you are on the map, another word for cilantro might be the only name anyone recognizes.
It's just a herb. Or is it? For some, it’s a fresh, citrusy pop that makes a street taco sing. For about 4% to 14% of the population, it tastes like a shavings of Dial soap. This isn't just people being picky; it's actually hard-coded into their DNA. Specifically, a variation in a cluster of olfactory receptor genes, including the OR6A2 gene, makes some people hyper-sensitive to the aldehydes in the plant. When they search for another word for cilantro, they might be trying to identify the culprit behind a ruined meal or simply trying to navigate a menu in a foreign country where "coriander" is the standard term.
The Global Identity Crisis of Coriandrum Sativum
In the United States, we’ve split the personality of this plant right down the middle. We use "cilantro" to describe the green, lacy leaves and stems. Then, we use "coriander" to talk about the dried seeds. It feels logical until you fly across the Atlantic. In the UK, Australia, and much of South Africa, it's all just coriander. You have coriander leaves, coriander stalks, and coriander seeds. If you ask a London grocer for cilantro, they’ll probably know what you mean because of American media, but you’ll definitely mark yourself as a tourist.
Spanish speakers gave us the word "cilantro." It's the Spanish translation of coriandrum. Because the United States shares a border and a deep culinary history with Mexico, we adopted their terminology for the fresh herb used in salsas and guacamoles. Meanwhile, the British took their cues from the French coriandre. It's a classic case of linguistic geography.
But wait, it gets more complicated. If you're hanging out in a Southeast Asian market, you might hear people calling it "Chinese parsley." This isn't technically wrong in a descriptive sense—the leaves look remarkably like Italian flat-leaf parsley—but they are entirely different species. If you accidentally swap parsley for cilantro in a pesto, you're going to have a very strange-looking dinner and a confusing flavor profile.

More Than Just a Name: Culantro and Rau Ram
Sometimes when people look for another word for cilantro, they aren't actually looking for a synonym. They might be looking for a substitute that actually tastes like the real thing but grows better in heat. Enter Culantro (Eryngium foetidum).
Don't let the name fool you. Culantro is not cilantro. They are cousins, sure, but culantro has long, serrated leaves that look more like a weed you'd find in your backyard than a delicate herb. It’s a staple in Caribbean, Central American, and Vietnamese cooking. The wild part? Culantro tastes like cilantro on steroids. It’s much more pungent and holds its flavor better when cooked, whereas the "normal" cilantro loses its punch the second it hits high heat. In Puerto Rico, it's a vital part of recaíto. If you can't find cilantro, or if you want a deeper, earthier version of that flavor, culantro is your best bet.
Then there's Rau Ram, often called Vietnamese Coriander. It has pointy leaves with dark markings and a flavor that starts like cilantro but finishes with a peppery, citrus kick. It loves the heat and doesn't bolt (go to seed) as fast as the standard variety. This is the stuff that gives certain Noodle soups and salads in Southeast Asia their signature "zing."
Why the Soap Gene Matters
We have to talk about the soap thing. It's not a myth. Dr. Nicholas Eriksson and his team at 23andMe actually did a massive study on this. They found that people who think cilantro tastes like soap usually have a specific genetic marker. These people are detecting the aldehydes—chemical compounds that are also found in soaps and some insects (specifically stink bugs).
If you're cooking for a crowd, this is a nightmare. This is why "coriander" or another word for cilantro can sometimes be a warning label. If you’re a "soaper," you might find that "another word" for this herb is simply "ruined dinner." Interestingly, some studies suggest that crushing the leaves (like in a pesto or a fine mince) can help break down those aldehydes, making it slightly more tolerable for the genetically unlucky among us.
Growing Your Own (Whatever You Call It)
If you decide to grow it, stop calling it cilantro for a second and think of it as a ticking time bomb. This plant hates the sun. It’s a "cool-season" herb. The moment the temperature spikes above 75°F (24°C), the plant decides its life is over. It shoots up a thick stalk, the leaves become lacy and bitter, and it produces white flowers. This is called bolting.

Once it bolts, you've lost your "cilantro," but you've gained your "coriander." You can let those flowers turn into green berries, which eventually dry out and become the coriander seeds you buy in the spice aisle. If you harvest them while they are still green, they have a wild, electric citrus flavor that is nothing like the dusty powder in your pantry.
A Quick Cheat Sheet for the Names You'll See:
- Cilantro: The standard American term for the fresh leaves.
- Coriander: The British/Australian term for the leaves, and the global term for the seeds.
- Chinese Parsley: An old-school name often found in Asian markets or older cookbooks.
- Mexican Parsley: Occasionally used in the American Southwest.
- Koriander: The German and Dutch spelling.
- Dhaniya: The term you’ll see in Indian grocery stores and on many authentic curry recipes.
- Kushniz: The Persian name for the herb, common in Middle Eastern contexts.
The Culinary Versatility Factor
Why do we bother with all these names? Because the herb is foundational. In Mexican cuisine, you cannot have a proper salsa verde without it. The acidity of the tomatillos needs the herbaceous lift of the cilantro. In Indian cooking, dhaniya is used twice—the powder goes in the base of the sauce, and the fresh leaves go on top at the very end.
If you're using the seeds (coriander), you’re dealing with a totally different beast. The seeds are warm, nutty, and citrusy. They are a primary ingredient in gin, for starters. They also bridge the gap between sweet and savory. You’ll find them in Moroccan rub for lamb and in Scandinavian pickles. It’s one of the few plants where every single part—the root, the stem, the leaf, and the seed—is not only edible but essential to different world cuisines. The roots, specifically, are a secret weapon in Thai curry pastes. They have a much more intense, earthy version of the leaf flavor that doesn't disappear when you simmer it for an hour.
Navigating the Grocery Store Like a Pro
Next time you’re shopping and you can’t find what you need, look for the synonyms. If the shelf is empty under "Cilantro," check the "International" or "Asian" produce section for "Chinese Parsley." If you’re in a specialty Indian market, look for "Dhaniya."

Don't confuse it with flat-leaf parsley. Seriously. They look identical at a glance. The trick? Look at the leaf tips. Parsley leaves are usually more pointed and rigid. Cilantro leaves are more rounded and delicate. If you're still not sure, do the "pinch test." Pinch a leaf and smell it. Parsley smells like fresh-cut grass; cilantro smells like a taco truck or, if you’re unlucky, a bar of soap.
Moving Forward With Your Herbs
Knowing the right terminology isn't just about being a pedant at dinner parties. It’s about grocery store survival. If you’re traveling through Europe or Asia, stop looking for "cilantro" on the menu and start looking for "coriander." If you’re in a Caribbean market, look for "culantro" to take your flavors to a higher level of intensity.
To get the most out of this herb, remember these three practical steps:
- Store it like flowers: Put your bunch of cilantro (or coriander leaves) in a glass of water in the fridge and cover the top with a loose plastic bag. It will last for two weeks instead of two days.
- Use the stems: Most people throw them away, but the stems actually have more flavor than the leaves. Chop them finely and sauté them with your onions and garlic at the start of cooking.
- Toast your seeds: If you’re using the "coriander" version of the plant, always toss the seeds in a dry pan for 60 seconds until they smell fragrant before grinding them. It changes the flavor from "meh" to "wow."
Whether you call it cilantro, coriander, or dhaniya, this plant is a global powerhouse. Just make sure your guests don't have that OR6A2 gene before you go heavy on the garnish.
