10 Health Benefits of Coriander
Coriander (Coriandrum sativum) is a culinary powerhouse used across the globe, with its leaves known as cilantro and its dried seeds simply as coriander. Its deep-rooted history in both food and traditional medicine is a testament to its wide range of properties. The benefits of coriander are attributed to its rich composition of vitamins, minerals, antioxidants, and essential oils.
1. Fights Free Radicals with Antioxidants
Coriander is packed with powerful antioxidants, including terpinene, quercetin, and tocopherols, which protect the body's cells from damage caused by free radicals. These compounds have been studied for their ability to fight inflammation, suggesting potential protective effects against chronic diseases, premature aging, and cellular damage.
2. Supports Heart Health
Several studies indicate that coriander can benefit cardiovascular health. It may help lower risk factors for heart disease, such as high blood pressure and LDL ('bad') cholesterol levels. Coriander extract has also been shown to act as a diuretic, helping the body flush out excess sodium and water, which can contribute to lower blood pressure. Additionally, consuming pungent herbs like coriander may help reduce overall sodium intake in meals.
3. May Lower Blood Sugar Levels
Coriander seeds and extracts are noted for their potential to help regulate blood sugar. Animal studies have shown that coriander can activate enzymes that help remove sugar from the blood, and can increase insulin release. This effect is significant enough that individuals with low blood sugar or those on diabetes medication should exercise caution and consult a healthcare provider.
4. Aids Digestive and Gut Health
Coriander seeds are a traditional remedy for digestive issues. Oil extracted from the seeds can accelerate and promote healthy digestion. An 8-week study on individuals with irritable bowel syndrome (IBS) found that a coriander-containing herbal medication significantly reduced symptoms of abdominal pain, bloating, and discomfort compared to a placebo. In traditional Iranian medicine, coriander extract is also used as an appetite stimulant.
5. Protects Brain Health
Coriander's anti-inflammatory properties may offer protection against several brain ailments, including Parkinson's and Alzheimer's, which are linked to inflammation. Some animal studies have suggested that coriander extract can help protect against nerve-cell damage and improve memory. The plant's high antioxidant load may also help neurons withstand oxidative stress, potentially improving lifespan and memory.
6. Fights Infections with Antimicrobial Properties
Coriander contains compounds with antimicrobial properties that help fight certain infections and foodborne illnesses. Dodecenal, a specific compound in coriander, has been shown to combat bacteria like Salmonella, a common cause of food poisoning. Test-tube studies also show that coriander seeds can fight bacteria responsible for urinary tract infections.
7. Promotes Skin Wellness
Coriander offers several benefits for skin health. Its antioxidants help protect skin cells from damage, which can contribute to premature aging and damage from ultraviolet B radiation. The antimicrobial and anti-fungal properties of coriander can also aid in treating skin conditions like mild rashes and acne. Traditional remedies often use coriander paste with other soothing ingredients to address various skin issues.
8. Boosts Vision Health
Rich in essential vitamins like Vitamin A, Vitamin C, and Vitamin E, coriander leaves have long been associated with promoting healthy eyesight. Vitamin A is crucial for feeding the retinas and maintaining eye moisture, helping protect vision. Regular consumption is thought to potentially help in the healing of conjunctivitis.
9. Potential for Heavy Metal Detoxification
Some research suggests that coriander may possess chelating properties, helping to bind and remove toxic metals from the body. While more human-based clinical evidence is needed, animal studies have shown protective effects against heavy metal toxicity, particularly mitigating damage to organs like the kidneys.
10. Reduces Anxiety and Stress
Emerging research indicates that coriander may have a calming effect on the nervous system. Animal studies demonstrate that coriander extract can be nearly as effective as some anti-anxiety medications in reducing symptoms. Human studies have also shown that coriander can influence brainwave activity and reduce negative emotions, providing a therapeutic effect on a person's psychological state.
