Health Benefits of Cilantro

Did you know?

The word 'cilantro' usually refers to the leaves of Coriandrum sativum (fresh or dried), while 'coriander' is mostly applied to the seeds of the plant, which are often used as a spice. Nevertheless, both terms are frequently used interchangeably in different countries.

Cilantro, also known as coriander (mostly for its seeds), is widely considered a culinary herb, and it has been consumed as such for centuries. However, a deeper look at traditional healing systems reveals that cilantro is also used for treating a variety of illnesses. Some of these folk uses have been investigated by modern science, revealing potential applications. Among the main cilantro's benefits for human health are the following:

  • Treating and preventing infections. Cilantro is a powerful antimicrobial agent, particularly useful for treating bacterial, fungal, and yeast infections.

  • Reducing anxiety and inducing restful sleep. Coriander seeds are particularly rich in essential oils that have a powerful effect on brain activity, inducing calming and sedating effects.

Cilantro has been traditionally used as a chelating agent, thought to remove heavy metals from the body and prevent food poisoning. This herb is also known to reduce blood sugar and promote cardiovascular health by lowering blood pressure and cholesterol.

How It Works

Did you know?

While the major constituents in the cilantro leaf oil are aromatic acids, coriander seed oil is particularly high in petroselinic acid and linalool, geranyl acetate, and γ-terpinene.1

The main bioactive compounds responsible for cilantro's health benefits are petroselinic acid, and linalool.

Petroselinic acid makes as much as 85% of the total fatty acid content of the coriander seed. This unique compound has displayed strong antimicrobial actions against many bacterial strains, yeast, and fungus. The essential oil from Coriandrum sativum has been shown effective against Candida yeast infections.2

On the other hand, linalool is an important terpene in cilantro as well as in many other herbs and a major component of essential oils. It has been shown to have powerful antioxidant, antimicrobial, and anti-inflammatory properties, but it also works on the central nervous system, reducing anxiety and inducing sleep. Linalool interacts with a neurotransmitter called Gamma-amino butyric acid (GABA), which works by regulating neural activity, causing relaxing effects that have been linked to improvements in mood disorders, such as anxiety and depression.3,4


Other herbs with antimicrobial and anti-fungal properties are garlic and thyme, whereas lemon balm and valerian have been traditionally used for reducing anxiety and as sleeping aids.

Cilantro Cautions

Both cilantro and coriander seeds are considered safe in culinary amounts. However, inhalation and ingestion of this aromatic herb may cause allergic reactions in sensitive people; symptoms include swelling inside the mouth and nose, difficulty breathing, and hives.

Likewise, high amounts of vitamin K in cilantro may hinder the actions of anticoagulants, so people with cardiovascular problems should consult a doctor before taking Coriandrum sativum in medicinal doses.

Cilantro Benefits and Properties

Cilantro Nutrition

As a culinary herb, cilantro not only provides unique flavor and medicinal properties, but also a wide range of nutrients and dietary fiber.

The most abundant mineral in cilantro leaves is cooper, which is essential for the production and transport of red blood cells as well as for proper iron absorption. Cilantro is also rich in potassium, which helps with fluid balance in the human body and blood pressure control, and manganese, necessary for strong bones and proper wound healing. Additionally, this herb is a good source of iron for maintaining healthy hemoglobin levels, thus preventing anemia.

Cilantro is an outstanding source of vitamin K (phylloquinone), which plays a role in the production of many proteins that are crucial for blood clotting and healthy bones. 100 grams of fresh cilantro leaves provide more than twice the recommended daily intake for this fat-soluble nutrient.

Other important vitamin that cilantro provides in generous amounts is vitamin C (ascorbic acid), necessary for iron absorption as well as for the biosynthesis of collagen, L-carnitine, and certain neurotransmitters. These cilantro's benefits for skin are complemented by high levels of vitamin A, essential for tissue regeneration and eyes health. On the other hand, vitamin E (alpha-tocopherol) is a powerful antioxidant that stops the production of harmful free radicals, thus preventing vision loss, vascular problems, and other age-related chronic conditions. Additionally, good amounts of vitamin B9 (folate) in cilantro ensure red and white blood cells production for a strong immune system, help transform carbohydrates into energy, and are crucial for DNA and RNA production.

Gardening tip

For home gardeners, sowing seeds of cilantro every 3-4 weeks will guarantee a constant supply of fresh leaves.

Cilantro is an annual herb, mostly grown for its seeds, known as coriander. It can grow up to 20 inches (50 cm) and can easily adapt to a variety of environments; however, this cool-season crop thrives under some specific conditions of soil, water, light exposure, and temperature.

Growing Guidelines

  • Cilantro is most commonly propagated from seeds, and it grows better in loamy soils with good drainage and a pH range of 6.5 to 7.5.

  • The cilantro plant likes cool environments, with plenty of direct sunlight or partial shade. It thrives in temperatures between 50-85°F (10-29°C), but it can survive temperatures as low as 10°F (-12°C).

  • The best thing about cilantro is that it can be grown both outdoors and indoors in a container placed in a sunny spot, like a windowsill.

  • The seeds of cilantro should be planted at a depth of 1/4 to ½ inches (0.6-1.27 cm), with a spacing of 2 inches (5 cm) between plants, in rows 12 to 15 inches (31-38 cm) apart.

  • It is crucial to keep the soil moist during the germinating process, while being careful not to overwater it. Once the cilantro plant is established, it will not need much water.

  • In cool, temperate climates, the seeds of cilantro take 1-2 weeks to germinate, and the plant can be harvested after 120 days. However, in warm regions, cilantro plants bloom 4-6 weeks after planting.

  • The best time to plant cilantro is after the last frost, or the first days of spring. The main harvests are between March and mid-November, whereas winter crops are harvested from November to March.

  • The main disease that affects cilantro is bacterial leaf spot. This crop is also attacked by some plagues, such as beet armyworms, cabbage loopers, and green peach aphids.

Plant Biology

Cilantro (Coriandrum sativum L.) is a cold season crop, soft and hairless, with leaves that are compound and variable in shape, and white to pale pink flowers that bloom in clusters of 2 inches (5 cm) across. The fruit of cilantro is a globular dry schizocarp, commonly known as coriander seed.

  • Classification

    With small flowers and rounded seeds, Coriandrum sativum is a species that belongs to the Apiaceae family, mostly comprised of aromatic plants, with 3700 species spread over 434 genera. This botanical family includes mostly temperate crops with umbellate inflorescences, such as anise (Pimpinella anisum), angelica (Angelica archangelica), arracacha (Arracacia xanthorrhiza), carrot (Daucus carota), celery (Apium graveolens), dill (Anethum graveolens), fennel (Foeniculum vulgare), osha (Ligusticum porteri), and parsley (Petroselinum crispum).

  • Species and varieties of cilantro

    The Coriandrum genus includes only two species, Coriandrum sativum and Coriandrum tordylum. Both are very similar, with the latter being a wild species native to parts of Turkey and Lebanon. Many varieties of Coriandrum are cultivated in different parts of the world. 

    For commercial purposes, coriander seeds are often categorized into three groups: East European (small seeds, high oil content, sweet aromatic flavor with slight lemon notes), North African and Spanish (large seeds, low oil content, and sweet aromatic flavor), and Indian (oval seeds with a distinguished, slightly bitter taste profile).

History of Cilantro

Native to the Mediterranean basin, south-western parts of Asia, and North Africa, it is thought that cilantro was first cultivated as a spice crop in the Asian side of Turkey (formerly known as Anatolia), from where it quickly spread to Egypt, Armenia, southeastern Europe, and southern Russia.

An Egyptian papyrus, dating back to 2500 to 1550 BCE, describes cilantro as a medicinal plant. The herb is also listed as an ingredient in a stew on clay tablets found in Mesopotamia. Cilantro has been cultivated for millennia in India and China and introduced into Mexico and Peru by the Spaniards.


Popular Beliefs

Curiously, 'manna' is likened to coriander seeds in the Bible, in order to describe the appearance of the mythical food that fell from the sky to feed the Israelites during their exodus from Egypt. According to an ancient Chinese belief, cilantro leaves and seeds confer immortality to those who consume them.

Economic Data

The main producers of cilantro are India, China, the former Soviet Union, Mexico, South America, Central America, and the Caribbean. In the United States, cilantro is commercially cultivated across the West Coast, mostly in California, but because of high demand, this country imports large amounts of this aromatic herb.

Other Uses of Cilantro

  • Gardening. Cilantro is not only cultivated for its flavor and medicinal properties, but also as a plant companion and pest control agent. Cilantro flowers attract beneficial insects, which pollinate other plants and destroy harmful bugs.

  • Fuel. Due to the high stability of their essential oils, coriander seeds are being evaluated as an alternative source of biodiesel.

  • Perfumery. Thanks to its sweet, spicy characteristics as well as soft, woody, and peppery nuances, coriander essential oil is often used as an undertone in many commercial fragrances.

Cilantro has become a common ingredient and spice around the world, so its rich history and health benefits are often overlooked. However, this humble herb is a powerhouse of medicinal and nutritional benefits, and it deserves a rightful place as part of a balanced diet and herbal cabinets.
