What is Estafiate?

Estafiate is a silver-grey herb in the daisy family. Its Latin name is Artemisia ludoviciana. It is also called western mugwort or white sagebrush.

People in Mexico and the US Southwest brew the dried leaves into a bitter tea. The tea is taken most often for an upset stomach. Healers also use it for gas, cramps, and worms in the gut.

Here is the short verdict. Its place in folk medicine is old and strong.

Human trials are almost absent, so we cannot say it works. Long use in a culture is not proof that a herb works.

How does Estafiate work?

No one has shown how estafiate works in people. The plant tastes very bitter. Bitter teas can make the gut move and make more digestive juice, which may explain its old use for a heavy, sour stomach.

Lab tests show the plant can slow the growth of some germs. Other lab tests show it can calm gut spasms in animal tissue. Animal tests show a drop in blood sugar.

These are early findings from dishes and mice. They do not tell us what a cup of tea does in your body.

What forms does Estafiate come in?

Dried leaf tea is by far the most common form. About a teaspoon of leaf is steeped in a cup of hot water.

You may also see tincture (a liquid extract made with alcohol), capsules of dried leaf powder, and a cooled tea used as a skin wash. Dried bundles are also burned as smoke in cleansing rites.

Pure estafiate essential oil is sold too. It is for scent and skin products only. Never drink it.

Where it comes from:

Estafiate has deep roots in Mexico. The Aztecs called it iztauhyatl and used it for stomach trouble and fever. Spanish scribes wrote it down in the 1500s.

Plains tribes in the United States used the same plant in their own way. It is still sold in markets and herb shops across Mexico and the US Southwest.

It also has a ritual role. Healers use it in cleansings for susto (a fright sickness in Mexican folk belief).

What does Estafiate help with?

• Upset stomach, gas and bloating: This is the main folk use, and it is very widely known in Mexico. The bitter tea is taken after a heavy meal. There are no human trials that test estafiate for this, so we cannot say it works better than warm water and rest.
• Stomach and gut cramps: Healers use the warm tea for a griping, cramping belly. Lab work on animal gut tissue shows the extract can relax muscle spasms. That work has not been repeated in people.
• Worms in the gut (folk use): Estafiate has an old name as a worm remedy across Mexico. Some lab tests show its chemicals can hurt parasites in a dish. There is no human trial showing it clears worms, and worm infections need a proper test and proven medicine from a doctor.
• Painful periods: The tea is a folk remedy for period pain and for late periods. This same action is why it is unsafe in pregnancy. No human trial has tested it for period pain.
• High blood sugar (folk use): Estafiate is one of the plants Mexican healers use for diabetes (high blood sugar). Mouse and rat studies do show lower blood sugar. Human proof is lacking, so never swap your diabetes medicine for tea.
• Colds and fever (folk use): The hot tea is taken for chills, fever and blocked sinuses. This use goes back to Aztec records. No trial has tested it, and a hot drink alone can ease cold symptoms.
• Empacho and susto (cultural folk illnesses): Empacho means food felt to be stuck in the gut. Susto means illness from a fright. Estafiate is part of these healing rites, and that role is cultural rather than medical. Trials cannot test it in that setting.

Which foods are rich in Estafiate?

1. Estafiate tea: dried leaf steeped in hot water, the usual way people take it
2. Estafiate tincture: a few drops of the alcohol extract in water

Practical Tips:

Estafiate is a medicinal herb, not a food, and it is far too bitter to be eaten as a vegetable or salad green.

What are the side effects of Estafiate?

• Very bitter taste, which can bring on nausea
• Stomach pain or vomiting if the tea is strong or you drink a lot
• Skin rash or itching, mostly in people allergic to the daisy family
• Headache or dizziness
• Fits (seizures) from the pure oil or from very large doses
• Risk of losing a pregnancy, because the herb can act on the womb

Good to know:

Most people who drink a normal cup of the tea have no trouble beyond the bitter taste. The serious effects come from the pure essential oil, from very strong doses, or from use in pregnancy.

Stop taking it if you get a rash, keep vomiting, or feel faint.

How much Estafiate should you take?

• Recommended daily: There is no proven safe dose. No study has set one. The usual folk amount is about 1 teaspoon (1 to 2 grams) of dried leaf in a cup of hot water. Steep it for 10 minutes, then strain it. People drink up to 2 or 3 cups a day. Start with one cup. Weak tea is safer than strong tea with this plant. Never swallow the essential oil at any dose.
• Best time of day: Most people drink it after a meal that sits heavy, or at the first sign of gas and cramps. A cup in the evening is common. Avoid taking it right before you drive until you know how it affects you.
• With or without food: Take it after food. The tea is strongly bitter and can turn your stomach on an empty belly.
• Time to effect: If the tea helps a heavy stomach, people report ease within 30 to 60 minutes. There is no trial to confirm this. It should not be used for weeks in hope of a slow build-up.
• How long to take it: Use it for a short spell only. A few days is the common folk pattern, and 1 to 2 weeks is a sensible limit. Stop and see a doctor if your stomach trouble is no better after a week. Long daily use has not been studied, and the thujone in the plant is a reason not to take it for months.
