Coriander Water Benefits: What Does It Actually Do?

The most plausible benefits of coriander water are hydration, digestive comfort and bowel regularity, although evidence for coriander seeds themselves is limited.

What are the 3 potential benefits of coriander water?

Coriander water is made by steeping coriander seeds in drinking water. Its clearest benefit comes from the water; the other two are possibilities rather than proven effects of the seeds.

1. Supporting hydration

Water replaces fluid your body uses throughout the day, and coriander seeds can give it a mild flavor. Drink coriander water in place of plain water if you enjoy it. Evidence strength: Strong for the role of water in hydration, but no special hydration effect from coriander seeds has been established.

2. Possibly supporting digestive comfort

Coriander seeds contain plant compounds, but it is unclear whether the amounts in coriander water affect digestion. You can drink it as a beverage if it agrees with you, rather than relying on it for symptom relief. Evidence strength: Limited; a human trial tested a combination herbal capsule, not coriander water or coriander seeds alone.

3. Helping support regularity through fluid intake

Getting enough fluid can help prevent constipation when inadequate fluid intake is a contributing factor. Use coriander water as one way to drink water during the day, not as a laxative. Evidence strength: Water’s role is established, but a trial involving coriander in a multi-herb laxative does not show that coriander water relieves constipation.

How does coriander water support hydration?

Coriander water is mostly water, so it contributes to your daily fluid intake. Staying hydrated supports normal bodily functions, including the work of the kidneys and digestion.

The coriander seeds are mainly there for flavor. If their taste makes water more appealing, coriander water may make it easier for you to drink enough. There is no need to choose it over plain water if you prefer plain water.

Unsweetened, strained infused water is generally very low in calories, usually under 10 kcal per glass. Its calorie content is not the same as the calories in the whole coriander seeds: most of the seeds are removed rather than eaten. Adding sweeteners or consuming the seeds changes what is in the drink.

Can coriander water improve digestive comfort?

Coriander seeds have been studied as part of a herbal preparation for functional dyspepsia, a condition involving recurring upper-abdominal symptoms. In a 2024 randomized, placebo-controlled trial, people who received a capsule combining coriander with Bunium persicum had greater improvements in the measured symptoms than those who received a placebo.

That result is interesting, but it does not establish that coriander seeds were responsible. The preparation combined two herbs, and a measured capsule is not the same as water steeped with coriander seeds. The trial also involved people with a diagnosed condition, so its results cannot be assumed to apply to occasional discomfort in everyone.

If you like coriander water, it is reasonable to enjoy it with or between meals. There is no established amount or timing that makes it a digestive treatment. Stop drinking it if it seems to make you uncomfortable, and speak with a clinician about symptoms that persist or keep returning.

Can coriander water help with bowel regularity?

Drinking enough fluid helps support normal bowel function, particularly if you have not been getting enough water. Coriander water can contribute to that fluid intake, but plain water can serve the same purpose. More fluid is not necessarily the answer to constipation when you are already adequately hydrated.

A 2025 randomized trial found that a multi-herb capsule improved postoperative constipation compared with a placebo. The capsule included coriander, but it also included several other herbs, including senna and aloe. Because the ingredients were tested together, the study cannot tell us whether coriander contributed to the result.

The trial did not test coriander water, and its participants had constipation after surgery. It is therefore not evidence that a coriander seed infusion is a laxative. Straining out the seeds also means the drink is not a substitute for eating fiber-containing foods.

What does coriander water not do?

Coriander water does not detoxify your body in a special way. The liver and kidneys do most of the body’s detoxification, while the lungs and gut help eliminate waste. Sweat removes only trace amounts of waste substances.

Drinking water supports normal organ function, but coriander water does not “flush toxins,” cleanse the blood or replace medical care. It has also not been shown to burn fat. Any weight-related change from choosing an unsweetened drink instead of a sweetened one would depend on the overall diet, not on a proven fat-burning property of coriander seeds.

Nor should the capsule studies be treated as proof that coriander water treats indigestion or constipation. The ingredients, preparations and people studied differ from a homemade infusion. Enjoy it for its flavor and fluid content, while keeping the other potential benefits in perspective.

How should you make and drink coriander water?

Use food-grade coriander seeds and safe drinking water. This simple infusion makes a lightly flavored drink; it is not a medicinal dose.

Ingredients

• 1 liter (about 4¼ US cups) drinking water
• 1 teaspoon (5 mL) whole coriander seeds

Method

1. Add the coriander seeds and water to a clean, covered pitcher.
2. Refrigerate for 2–4 hours to let the flavor develop.
3. Strain out the coriander seeds, if desired, and serve chilled.
4. Keep the remaining coriander water refrigerated. Drink it within 24 hours for best flavor, and discard it after 2–3 days or sooner if it becomes cloudy, slimy or sour-smelling. Do not leave it at room temperature for more than a few hours.

You can drink coriander water when you would normally have water. There is no proven best time of day or required number of glasses for coriander-specific benefits. If you have been advised to limit fluids because of a medical condition, follow your clinician’s instructions rather than adding extra drinks.

Who should be careful?

Avoid coriander water if you have an allergy to coriander seeds. If you develop symptoms such as hives or swelling after drinking it, stop; seek emergency help for trouble breathing or swelling of the tongue or throat.

Food amounts of coriander seeds are different from concentrated herbal products. If you are pregnant or breastfeeding, taking medication, or considering a concentrated coriander product for a child, ask a healthcare professional before using it. Seek medical advice for persistent digestive symptoms; severe abdominal pain or blood in the stool needs prompt medical attention.

The available human studies below tested herbal capsules, not coriander water. Both were randomized trials, but neither isolated the effect of coriander seeds:

• 2024 trial of coriander and Bunium persicum for functional dyspepsia.
• 2025 trial of a multi-herb capsule for postoperative constipation.
