August 29th Is More Herbs Day: Here Are the Benefits of Cilantro

Cilantro—aka the leaves of the coriander plant—is a bright green herb commonly used in Mexican, Asian, and Middle Eastern cooking, as well as other cuisines around the globe. Apart from its somewhat citrusy, peppery flavor (to most people, anyway), cilantro is added to dishes for its potential health perks. Here's the lowdown on cilantro's benefits, plus how to eat it and why some people simply cannot bear the way it tastes.

Cilantro benefits

There is little research into the health benefits of cilantro. However, research indicates this leafy garnish has a few potential perks.

1. Cilantro is a good source of nutrients

In addition to color and flavor, cilantro adds nutrition to your plate. A quarter cup of raw cilantro leaves (about the size of a golf ball) provides 16% of the daily value (DV) of vitamin K, which supports bone health and helps wounds heal. It also offers 5% DV of vitamin A and 2% DV of vitamin C—two vitamins responsible for immune function. Plus, said serving size adds less than one calorie to your meal.

2. Cilantro contains antioxidants

Beyond its vitamin value, cilantro also offers up important compounds called antioxidants, according to a 2022 review published in the journal Molecules. While cilantro has many types of antioxidants, one class, known as polyphenols, is particularly important. Why? Polyphenols reduce inflammation and prevent cell damage that may have otherwise contributed to premature aging and heightened disease risk.

3. Cilantro may help cardiovascular health

Traditional medicine has long used parts of the coriander plant (including cilantro leaves) to treat pain, inflammation, gastrointestinal problems, and diabetes. While most of the medicinal properties of the plant have yet to be studied, the same 2022 review published in Molecules found the herb may have cardiovascular benefits, such as regulating blood pressure and heart rhythm. The researchers theorize that this is due to cilantro’s high antioxidant content.

However, of the 18 studies the review assessed, only two were conducted in humans. Therefore, you shouldn't expect munching on cilantro to ease any cardiovascular issues; a lot more research needs to be done.

Why You Should Never Throw Away Parsley and Cilantro Stems

Potential drawbacks of cilantro

In general, cilantro has few downsides, especially when it comes to nutrition content. However, a few people may want to avoid cilantro. For example, up to 14% of the population has a genetic variant that makes them highly sensitive to the smell of a compound in cilantro called aldehydes. Since smell and taste are so closely linked, this can make the fresh, citrus-esque herb taste like soap or dirt instead.

Additionally, because cilantro is often consumed raw, it poses the risk of being contaminated with bacteria that would have otherwise been killed via cooking. Between 1998 and 2017, at least 20 cilantro-associated foodborne outbreaks were reported to the Centers for Disease Control and Prevention. This led to 659 illnesses and 67 hospitalizations, according to Colorado State University’s Food Source Information site. If you’re at a higher risk of developing a more serious illness due to foodborne bacteria—for example, you’re pregnant, over 65, or have a pre-existing medical condition—youshould talk to your healthcare provider about whether you should only consume cooked cilantro.

The herb can also negatively interact with certain medications or other herbs, according to the Natural Remedies Comprehensive Databases. Therefore, be sure to consult a doctor or other qualified health care provider before you consume large amounts of cilantro.

How to eat cilantro

If you’re looking to easily bump your intake of antioxidants and vitamins, garnishing dishes with raw cilantro may be for you. Sprinkle it atop guacamole, salads, beans, stir-fries, soups, fish, curries, and more. Even if you’re not a huge fan of plain, raw cilantro, go online and find recipes that incorporate this herb, such as pico de gallo, pesto, chutney, and even cocktails. One of my favorite pairings is roasted corn with chopped cilantro and fresh lime. The key is to have fun experimenting with ways cilantro can freshen up a dish.
