Coriander seeds come from the same plant as cilantro (which are the leaves). They are common ingredients in curries. The seeds look small and round, are kelly green/yellowish brown, and have a lemony citrus flavor.
The seeds offer multiple health benefits. Among the most important of those is their ability to lower cholesterol levels (1). The seeds can also help manage diabetes and relieve symptoms of arthritis.
Research lately has discovered the many ways you can use the seeds to achieve optimum health. The studies we will discuss will tell you the exact ways these seeds can benefit you.

What Are The Health Benefits Of Coriander Seeds?
The antioxidants in coriander seeds promote heart health by lowering blood cholesterol levels and reducing blood pressure. The fiber in the seeds boosts lipid metabolism. The fatty acids (linoleic, oleic, and palmitic acids) and essential oils (linalool, camphene, and terpene) are responsible for the digestive and carminative properties of coriander seeds.
1. Promote Heart Health
Coriander seeds have a remarkable cholesterol-lowering action. Rat studies showed that those fed with coriander seeds experienced a decrease of total cholesterol and triglycerides in their tissues (2).
The seeds also improved the levels of good cholesterol (2).
Coriander seeds can also inhibit the aggregation of human platelets. If platelet aggregation occurs in the arteries, it can lead to impaired blood flow to the heart and eventual heart attack (2).
Coriander plays an important role in the metabolism of lipids in the human system. Studies show that it can also regulate blood pressure levels (3).
The antioxidant properties of coriander seeds may help lower blood pressure levels. They help widen blood vessels, thereby lowering blood pressure (4).
2. Aid Diabetes Treatment
Coriander seeds can help lower blood sugar levels. They achieve this by improving the function of the pancreatic beta cells (cells that release insulin and regulate blood sugar levels) (5).
Other studies also validate the use of coriander seeds for managing diabetes. In a rat study, the extracts of coriander seeds not only regularized blood sugar levels but also improved other factors associated with metabolic syndrome (6).
Regular intake of coriander seeds can also reduce the risk of cardiovascular complications associated with prediabetes, type 2 diabetes, and metabolic syndrome (7).
3. Enhance Digestion
Coriander seeds have long been used as digestive stimulants (8). The seeds may stimulate the liver to produce and secrete concentrated bile acids. These acids play an important role in digestion and absorption.
Coriander seeds also have carminative effects (relieving flatulence (8).
The seeds also enhance digestion by improving the activity of trypsin, a pancreatic enzyme that breaks down proteins in the small intestine (8).
Coriander seeds offer these digestive benefits best when included in your daily diet (8).
The oil from coriander seeds can also relieve the painful symptoms of irritable bowel syndrome (9). The antibacterial properties of the seeds may be responsible for this effect.
Coriander seeds can also help cure nausea and diarrhea (10). You can drink tea made from the seeds (steeping the seeds in hot water and then draining them after 15 to 20 minutes) to achieve these benefits.
4. May Relieve Arthritis Symptoms
Coriander seeds can relieve arthritis pain by fighting the activity of pro-inflammatory cytokines in the synovium (a membrane that lines the inner surface of a joint) (11). Pro-inflammatory cytokines are compounds in the human system that promote inflammation.
Coriander seeds can be used externally as a poultice to treat arthritis pain. Cineole and linoleic acid, two important compounds in the seeds, offer anti-rheumatic and anti-arthritic properties (12).
5. May Help Treat Conjunctivitis
Research shows that coriander seeds can treat itchy eyes, a major symptom of conjunctivitis (13). In the study, the group treated with a coriander seed spray experienced improved symptoms of conjunctivitis and itchy eyes.
6. May Promote Menstrual Health
There is very less research available on the efficacy of coriander seeds in treating menstrual symptoms. But some sources suggest that tea made of coriander seeds (along with rose petals) can ease menstrual discomfort, including menstrual cramps (14).
7. Boost Neurological Health
Linalool is a major compound in coriander seeds (and their oil). Studies show that linalool can reduce anxiety in humans (15).
Linalool has beneficial effects on the central nervous system. It also has anticonvulsant properties (reduces the risk of seizures or epileptic fits) (15).
The seeds can also play a protective role in the prevention of neurological diseases like Alzheimer’s. They were found to improve memory in mice, though the effects have been noticed only in coriander leaves (16).
Coriander seeds are a common ingredient. They are often added to dishes to enhance their taste and flavor. But not many are aware of the incredible benefits the seeds offer.
They have an exemplary nutrition profile. The following section showcases that in detail.

Including coriander seeds in your diet is quite simple. But if you do not want to go the regular way, check out the options in the next section.
How To Include Coriander Seeds In Your Diet
Do keep in mind to buy coriander seeds and not coriander powder. The latter loses its flavor rather quickly. You can buy the seeds from your nearest supermarket or online.
Before you use them, you need to first prepare them. Dry fry the seeds. Heat a frying pan (no oil) and add the seeds and fry them over medium heat. When you sense the warm aroma being released, you know that the seeds are ready. Remove from the pan and let them cool.
You can then enjoy the seeds in the following ways:
- Add the seeds to broths or soups.
- Add them to the poaching liquid while preparing fish.
- Combine the seeds with spinach, fresh garlic, and garbanzo beans. Season with ginger and cumin for a healthful snack.
It is hard to substitute coriander seeds with anything else, given their distinct flavor. But if the need arises, you can combine crushed fennel and caraway seeds along with some cumin.
You can store the seeds in an airtight jar in a cool and dry place for several months.
Before you go ahead and get your pack of fresh coriander seeds, you must know something else.
Do Coriander Seeds Have Any Side Effects?
- May Cause Allergies
Coriander seeds may cause allergies in some individuals (due to cross-reactivity by the mugwort pollen) (17). The symptoms might include any or all of the following – itching of the lips, mouth, and throat, itchy eyes, and fever.
Stop intake if you notice any of these symptoms.
- May Lower Blood Sugar Way Too Much
We know that coriander seeds can lower blood sugar levels (5). Hence, if you are already on medications for high blood sugar, please check with your doctor. They can adjust your dosage accordingly. You might have to control the quantity of coriander seeds that you consume.
