What is sacha culantro?

Sacha culantro is a strong-tasting leaf herb used in Latin American and Caribbean cooking. The plant is Eryngium foetidum. Its long, saw-edged leaves taste like coriander, only sharper.

Cooks chop it fresh into sofrito, rice, beans, soups and hot sauces. Home healers also brewed the leaf as a tea for fevers, colds, gas and stomach pain.

Here is the short verdict on evidence. As a food, it is well known and eaten daily by millions. As a medicine, good human studies are almost absent, and long traditional use is not proof that it works or that it is safe.

How does sacha culantro work?

No one has shown how sacha culantro acts inside the human body.

Most lab interest is in the leaf oil. In test tubes, a compound called eryngial kills the larvae of a gut worm. In rodents, leaf extracts have eased swelling and pain.

Rodent work also reports a calming, sleepy effect. One set of animal studies found a delay in fits brought on by chemicals. That is animal data only, and it does not show the herb treats seizures or anxiety in people.

In lab dishes, leaf extracts slow the growth of some bacteria and soak up free radicals. Whether any of that happens in a person who eats the leaf is not known.

What forms does sacha culantro come in?

Most people meet it as a fresh green herb in the vegetable aisle.

Forms you may see: - fresh leaves, sold in bunches - dried or freeze-dried leaf flakes - frozen leaf paste, and bottled sofrito or green seasoning - leaf tea, usually made at home - a distilled leaf essential oil - capsules and tinctures, which are uncommon

The fresh leaf has the longest record as food. Dried leaf keeps some flavour but loses much of the scent.

The essential oil is a different thing. It is very concentrated and is not a food. Treat it as a scent product, not a drink.

Where it comes from:

Sacha culantro has served as both a kitchen herb and a home remedy for centuries.

It grows wild and in gardens across Mexico, Central America, the Amazon basin and the islands. Colonial-era writers noted it in local cooking and healing. Trade later carried it to West Africa and South East Asia.

In parts of the Caribbean it is called fit weed. Healers gave the leaf tea to children during fits, and the name stuck.

Latin American folk use also covered fevers and chills, colic, gas, worms, burns and snake bite. Those are records of what people did, not records of what worked. This page does not suggest copying them.

What does sacha culantro help with?

• Gas, bloating and stomach cramps: This is the most common home use across Latin America. The leaf tea was drunk after heavy meals. No human trial has tested it for this. Some animal work hints at a relaxing effect on gut muscle. Any relief you feel may come from the warm drink itself.
• Colds, fever and chills: Tradition used the leaf tea to "break" a fever and ease chills. There is no human evidence that it shortens a cold or lowers a fever. Lab tests show some antibacterial action in dishes, which is not the same as treating an infection in a person.
• Joint and muscle pain: Crushed leaves and leaf teas were used for aches and swelling. In rodents, leaf extracts reduced swelling and pain signals. No controlled human study has tested this. Do not use it in place of care for ongoing joint pain.
• Intestinal worms: This is the use with the most lab support, and even that support is thin. Eryngial from the leaf oil killed larvae of the worm Strongyloides in test tubes, and helped in animal tests. There are no published human trials. Worm infections need a proper diagnosis and proven medicine.
• Fits (seizures), in folk use only: The Caribbean name fit weed comes from this use in children. Animal studies show a delay in chemically caused fits. There is no human evidence at all. Seizures are a medical emergency risk, and this herb must never replace epilepsy medicine.
• High blood pressure and high blood sugar, in folk use only: Folk healers used leaf teas for both. Some animal studies report small drops in blood sugar. No human trial supports either use. Keep taking the medicine your doctor prescribed, and keep your usual checks.

Which foods are rich in sacha culantro?

1. Puerto Rican and Dominican sofrito
2. Trinidadian green seasoning (chadon beni)
3. Caribbean pepper sauces
4. Amazonian fish and rice dishes
5. Vietnamese pho and fresh-herb plates
6. Thai larb and soups

Practical Tips:

In food, the leaf is used in small, flavouring amounts.

A pot of sofrito may hold a handful of leaves and feed a family for a week. This is the level of use with centuries of record behind it.

You cannot reach a "medicinal" amount by normal cooking, and there is no good reason to try.

What are the side effects of sacha culantro?

• Tingling or burning in the mouth from the strong taste
• Nausea or stomach upset after a strong tea
• Drowsiness after large amounts (seen in animals, not confirmed in people)
• Rash or itch in people allergic to carrot-family plants
• Skin burning or redness from the undiluted essential oil
• Possible skin sensitivity to sun after heavy skin contact

Good to know:

Eaten as a food herb, side effects are rare and mild.

The risk rises with strength. Concentrated teas, capsules and extracts have not been studied for safety in people.

The essential oil is the real hazard on this page. It can irritate or burn skin, and it is not meant to be swallowed.

How much sacha culantro should you take?

• Recommended daily: No medicinal dose has been set for people, because the trials that would set one do not exist. As a food, it is measured in leaves. A few chopped leaves season a whole pot of food, and that is the amount with a long record of safe use. Packed teas and capsules carry a label amount. That number comes from the maker, not from human studies. This page gives you no personal amount and no recipe for a medicinal strength tea. The essential oil should not be swallowed at all.
• Best time of day: Time of day does not matter for the food herb. Use it when you cook. If a product makes you sleepy, avoid it before driving. Animal work shows a calming effect, so this is a sensible caution rather than a proven risk.
• With or without food: It is food, so with food is the normal way to use it. A strong tea on an empty stomach may feel harsh and can cause nausea in some people. Taking it with or after a meal is gentler.
• Time to effect: As a flavour, the effect is instant. As a remedy, there is no honest timeline. No human study has measured how fast it acts, or whether it acts at all. It may do nothing for your symptom. Treat any quick relief from a warm tea as comfort, not proof.
• How long to take it: As a cooking herb, people use it year after year with no known problem. For strong teas, capsules or extracts, no safe length of use has been studied. There is no evidence to support weeks of daily medicinal use. If you are taking it for a symptom and nothing changes, that is a sign to stop and ask a doctor.
