3. May benefit heart health
Some animal and test-tube studies suggest that coriander may lower heart disease risk factors, such as high blood pressure and LDL (bad) cholesterol levels (13Trusted Source, 14Trusted Source).
Coriander extract appears to act as a diuretic, helping your body flush excess sodium and water. This may lower your blood pressure (13Trusted Source).
Some research indicates that coriander may help lower cholesterol as well. One study found that rats given coriander seeds experienced a significant decrease in LDL (bad) cholesterol and an increase in HDL (good) cholesterol (15Trusted Source).
What’s more, many people find that eating pungent herbs and spices like coriander helps them reduce their sodium intake, which may improve heart health.
In populations that consume large amounts of coriander, among other spices, rates of heart disease tend to be lower — especially compared with people on the Western diet, which packs more salt and sugar (16Trusted Source).
SUMMARYCoriander may protect your heart by lowering blood pressure and LDL (bad) cholesterol while increasing HDL (good) cholesterol. A spice-rich diet appears to be associated with a lower risk of heart disease.
4. May protect brain health
Many brain ailments, including Parkinson’s, Alzheimer’s, and multiple sclerosis, are associated with inflammation (17Trusted Source, 18Trusted Source, 19Trusted Source).
Coriander’s anti-inflammatory properties may safeguard against these diseases.
One rat study found that coriander extract protected against nerve-cell damage following drug-induced seizures, likely due to its antioxidant properties (20Trusted Source).
A mouse study noted that coriander leaves improved memory, suggesting that the plant may have applications for Alzheimer’s disease (21Trusted Source).
Coriander may also help manage anxiety.
Animal studies demonstrate that coriander extract is nearly as effective as Diazepam, a common anxiety medication, at reducing symptoms of this condition (22Trusted Source).
Keep in mind that human research is needed.
SUMMARYThe antioxidants in coriander may reduce brain inflammation, improve memory, and reduce anxiety symptoms, though more research is needed.
5. May promote digestion and gut health
Oil extracted from coriander seeds may accelerate and promote healthy digestion (23).
One 8-week study in 32 people with irritable bowel syndrome (IBS) found that 30 drops of a coriander-containing herbal medication taken thrice daily significantly decreased abdominal pain, bloating, and discomfort, compared with a placebo group (24Trusted Source).
Coriander extract is used as an appetite stimulant in traditional Iranian medicine. One rat study noted that it increased appetite, compared with control rats given water or nothing (25Trusted Source).
SUMMARYCoriander may reduce unpleasant digestive symptoms like bloating and discomfort often experienced by people with IBS. It may also boost appetite among some people.
Coriander contains antimicrobial compounds that may help fight certain infections and foodborne illnesses.
Dodecenal, a compound in coriander, may fight bacteria like Salmonella, which can cause life-threatening food poisoning and affect 1.2 million people annually in the United States (26Trusted Source, 27Trusted Source).
Additionally, one test-tube study revealed that coriander seeds are among several Indian spices that can fight the bacteria responsible for urinary tract infections (UTIs) (28Trusted Source).
Other studies suggest that coriander oil should be used in antibacterial formulations due to its ability to fight foodborne illnesses and hospital-acquired infections (29Trusted Source, 30Trusted Source).
SUMMARYCoriander exhibits antimicrobial effects that may help fight foodborne illnesses and pathogens like Salmonella.
Coriander may have several skin benefits, including for mild rashes like dermatitis.
In one study, its extract failed to treat diaper rash in infants on its own but could be used alongside other soothing compounds as an alternative treatment (31Trusted Source, 32Trusted Source).
Other studies note that the antioxidants in coriander extract may help prevent cellular damage that can lead to accelerated skin aging, as well as skin damage from ultraviolet B radiation (33Trusted Source, 34Trusted Source).
Furthermore, many people utilize coriander leaf juice for skin conditions like acne, pigmentation, oiliness, or dryness. Nonetheless, research on these uses is lacking.
SUMMARYCoriander contains antioxidants that may protect your skin from aging and sun damage. It may also help treat mild skin rashes.
8. Easy to add to your diet
All parts of the Coriandrum sativum plant are edible, but its seeds and leaves taste very different. While coriander seeds have an earthy flavor, the leaves are pungent and citrus-like — though some people find that they taste like soap.
Whole seeds can be added to baked goods, pickled vegetables, rubs, roasted vegetables, and cooked lentil dishes. Warming them releases their aroma, following which they can be ground for use in pastes and doughs.
Meanwhile, coriander leaves — also called cilantro — are best to garnish soup or use in cold pasta salads, lentils, fresh tomato salsa, or Thai noodle dishes. You can also purée them with garlic, peanuts, coconut milk, and lemon juice to make a paste for burritos, salsa, or marinades.
SUMMARYCoriander seeds and leaves both come in handy for everyday cooking but offer very different flavors that determine their best uses.
Coriander is a fragrant, antioxidant-rich herb that has many culinary uses and health benefits.
It may help lower your blood sugar, fight infections, and promote heart, brain, skin, and digestive health.
You can easily add coriander seeds or leaves — sometimes known as cilantro — to your diet.
Keep in mind that many of the above studies use concentrated extracts, making it difficult to know how much coriander seeds or leaves you would need to eat to reap the same benefits.
