Fact Checked

Mercola Fact-Checking Guidelines

  • Fact-checked
  • Vetted
  • Verified

All Mercola articles are fact-checked, vetted and verified using Associated Press and Society of Professional Journalists journalism standards. Because we hold ourselves to the highest level of excellence and take responsibility for our work, we also follow industry best practices as recommended by the American Copy Editors Society for editing, proofing, writing and content.

We follow ethics principles recommended by the Associated Press Media Editors, and we even have adopted Associated Press style guidelines to distinguish our writing style from other health sites.

Therefore, when it comes to the topics we cover, we fact check every claim we make, and clearly identify sources, vet the people we interview and write about, and verify all medical information with referenced, hyperlinked, medical literature sources.

We do use news hooks gathered from mainstream print and broadcast media, but we don’t rush to print our version of the story in the name of a “scoop.” Instead, we take time to investigate the article topic and dig deeper than what you see in other health and news sites — including mainstream news media — asking ourselves: Are the quotes accurate? Is there a backstory the news source missed that we need to share with our readers? Is the article accurate and honest?

To that end, we investigate the authors of medical and environmental studies headlined in the news so we can tell you what conflicts of interest they may have that could bias whatever it is they’re reporting. Because we also act as a watchdog over Big Industry and government, we take special care to look at the funding of studies and the lobbying behind legislation so we can expose questionable financial liaisons that ultimately affect your health and health care.

And, whether it’s a fun feature on nutrition or an in-depth investigation of Big Industry, we strive to gather all the facts possible, backed by research and investigative reporting, and relay them to you in a straightforward, conversational tone that you can understand and trust. In other words, we want you to know that you can depend on Mercola.com to tell a researched, factual, “rest of the story” that you won’t find anywhere else.

Story at-a-glance

  • Originally, the herb was grown in present day Greece and was utilized by ancient Egyptians and Romans, making cilantro one of the oldest known herbs in history
  • A medical report noted that when 200 milliliters of 10 percent cilantro extract was consumed for seven straight days, it led to severe diarrhea, stomach pain, darkened skin, menstrual lapse and dehydration

Most people typically associate cilantro with its soapy aftertaste1 or its "bedbug-infested bedclothes" odor and, for some, this could be more disgusting than appetizing even though others seem to enjoy it. In fact, as "The Curious Cook," Harold McGee, writes in The New York Times, although food can be a universal language, it can become divided as far as cilantro is concerned. He says:2

"Food partisanship doesn't usually reach the same heights of animosity as the political variety, except in the case of the anti-cilantro party. The green parts of the plant that gives us coriander seeds seem to inspire a primal revulsion among an outspoken minority of eaters."

Cilantro comes from a plant called Coriandrum sativum,3 and this herb belongs to the Apiaceae family. Also called Chinese or Mexican parsley in some areas,4 cilantro is said to be native to the Mediterranean and Asia Minor regions.5

Originally, the herb was grown in present day Greece and was utilized by ancient Egyptians and Romans, making cilantro one of the oldest known herbs in history.6 What most people do not know about cilantro, however, is that it is both an herb and a spice,7 because the plant also bears aromatic seeds — more popularly known as coriander seeds — that have their own health benefits, too.8

The Countless Health Benefits of Cilantro

It's no surprise that adding cilantro to dishes not only enhances the flavor, but also provides health benefits. The nutritional content of this low-calorie,9 no-cholesterol herb is very impressive, since it is abundant in:10,11

  • Antioxidant polyphenolic flavonoids such as quercetin,12 kaempferol, rhamnetin and epigenin
  • Minerals like potassium,13 calcium, manganese, iron and magnesium14
  • Vitamins A,15 C and K, as well as B vitamins

Cilantro is also proven to have antiseptic, antifungal, antioxidant16 and antibacterial properties17 that can contribute to numerous health benefits, such as:18,19,20,21

  • Helping reduce swelling caused by arthritis and rheumatic diseases because of its phenolic acids and polyphenols22
  • Lowering levels of bad cholesterol in your body
  • Reducing unhealthy LDL cholesterol levels
  • Helping with bone regrowth23
  • Stimulating digestion
  • Regulating blood sugar levels
  • Assisting in preventing stomach disorders like nausea and vomiting,24 and in alleviating gas and indigestion25
  • Acting as a potent chelator to remove heavy metals and toxins from your body26
  • Helping reduce risk for vision disorders like macular degeneration
  • Lowering stress on your eyes and shielding them from free radical damage

The leaves, root and stem of cilantro have also been shown to work against certain conditions, such as:

  • Eczema27
  • Dry or dull skin28
  • Fungal infections29
  • Anemia30
  • Muscle aches and pains31

Using cilantro medicinally may have certain side effects, though, such as allergic skin reactions (hives or itching)32 and photosensitivity.33 Consult your physician before using this as an herbal remedy to ensure that you have no allergies to this herb.

What Is Cilantro Mainly Used For?

Cilantro leaves are primarily used for culinary and medicinal purposes,34 although you can utilize cilantro essential oil for aromatic reasons as well (this will be discussed further).35 Arguably, many people are familiar with cilantro as an ingredient in many recipes. It may feature prominently in some dishes across various cuisines:36

  • Middle Eastern
  • Mediterranean
  • Indian
  • South Asian
  • Mexican
  • Latin American
  • Chinese
  • African
  • Southeast Asian

Cilantro pairs well with many dishes, especially those containing beans, eggs, cheese and fish. Plus, you can add cilantro into vegetable dips or use it as a garnish for soups and salads.37

Research Has Proven Cilantro's Potential Water-Purifying Abilities

A study conducted by a group of American and Mexican researchers also revealed that cilantro can help purify water. The discovery was made by a team led by Douglas J. Schauer, Ph.D., then of IvyTech Community College in Lafayette, Indiana, along with researchers from the Universidad Politecnica de Francisco I. Madero in Hidalgo, Mexico, while studying in the Tule Valley region.

Wastewater from Mexico City is dumped in this region. However, this waste water, contaminated with heavy metals like nickel and lead, is actually being used to irrigate crops.

According to Schauer, while other filtering agents such as activated charcoal can be used to remove the chemicals from the water, they are too expensive. The researchers then tested samples of different plants ranging from cacti to flowers, and learned that cilantro is a very powerful "bioabsorbant" material in this region. An item is considered bioabsorbant when it's made from dried organic material from a plant, and can essentially replace the charcoals typically utilized in filters.

As Schauer points out in a Time interview, ground-up cilantro can be placed inside a tube where the water can pass through. The herb allows water to trickle out, while filtering out dangerous heavy metals. Another method involves placing dried cilantro in tea bags and into a water pitcher for a few minutes, allowing the herb to draw out toxins.38

Growing Cilantro at Home

Cilantro is a cool-season herb that reaches its full potential when sown either in spring or fall. Temperatures between 50 and 85 degrees F are the most ideal for this plant.39 Cilantro can also be grown in warm temperatures, but make sure to plant slow-bolt cilantro varieties like Santo and Marino40 since the plant may grow quickly once the temperature rises.41

Healthy soil is important when growing your cilantro. It thrives well in rich soils with pH levels of 6.2 to 6.8. Feel free to add organic matter to the soil too, since this is a fast-growing plant.42

Country Living Magazine notes that it's best to grow cilantro plants using seeds. Sow the seeds one-fourth inch deep into the ground and leave a half-inch of space between plants. You may also try growing these plants indoors or in a pot, provided that they receive adequate sunlight and water.43

It takes 45 to 70 days after seeding for your cilantro plants to be ready for harvesting. Leaves that are 4 to 6 inches long can be snipped off and harveted.44 If you want a steady supply of cilantro, try planting small patches of the herb every two to four weeks throughout the growing season.45

Easy Cilantro Recipes You Should Try

If you haven't used cilantro in any of your dishes yet, what are you waiting for? Purchase fresh cilantro leaves, ideally from an organic farmer. Organically grown cilantro may have better flavor and contain many vitamins and antioxidants, without the added risk of pesticides and chemicals.

Look for fresh cilantro with vibrant green leaves, without indicators of spoilage or yellow discoloration. Keep fresh stems in a glass of water, cover the opening loosely with a plastic bag and then refrigerate them. Fresh cilantro can last for a week in the refrigerator, and maybe even longer if you follow these storage tips:46

  • Recover the glass of water after cutting off cilantro leaves.
  • Change the water in the glass every two to three days.
  • Avoid washing the herb until before using it because increased moisture may cause the leaves to turn into a slimy green color.

To prepare cilantro for cooking, make sure it has been thoroughly dried, and have a sharp ceramic knife ready. The book, "Rick Bayless Mexican Kitchen," suggests the following steps for chopping cilantro:47

  1. Bunch the leafy ends of the herb together.
  2. Fold under the top portion of leaves.
  3. Slice across the cilantro very thinly, including the stems. Continue doing so all the way down the herbs until there are no more leaves left and you only have stems.
  4. Using your fingertips, "fluff" the thinly sliced cilantro multiple times so the stems fall to the bottom of the pile.
  5. Separate the fluffed and sliced leaves and transfer them onto a small dish.

Avoid using a dull knife or over-chopping cilantro, as these can "bruise" the herb and cause its unique flavor to spill onto the chopping board. Ideally, try adding cilantro raw or near the end of the cooking process. This herb is very tender and has gentle leaves, so adding it last will retain cilantro's delicate flavor and texture.48

Cilantro can hold its own ground in terms of flavor and does not need additional flavoring. Because of this, raw and fresh cilantro leaves make recipes like Sunflower Power Salad, Cabbage Crunch or Land and Sea Salad taste great.

Cilantro Essential Oil Could Be Helpful, Too

Aside from consuming fresh cilantro, you can use cilantro essential oil to your advantage if you want to gain some of the benefits the herb has to offer. There are numerous ways you can use cilantro essential oil at home:49

  • Diffusion or inhalation via a vaporizer
  • Topical application
  • Food ingredient50

Before using or consuming cilantro essential oil, make sure to dilute it in a safe carrier oil like coconut or olive oil. Consult a physician and take an allergen patch test to see if your skin responds well to the oil. If you're pregnant, nursing or have kidney issues, avoid using this essential oil since it may exacerbate certain conditions.51
