Alcachofa

What is Alcachofa?

Alcachofa is the globe artichoke, Cynara scolymus. It is a large thistle eaten as a vegetable. In Latin America the leaves are also brewed as tea or sold as drops and capsules.

The part used as a remedy is the leaf, not the fleshy heart you eat. The leaf is very bitter. Home use has focused on the liver, the gallbladder and heavy, fatty meals.

The honest verdict: evidence is mixed and mostly early. Small trials point to mild help for indigestion and a small drop in cholesterol. Long use in tradition is not proof that it works, and not proof that it is safe.

How does Alcachofa work?

The main proposed mechanism is bile. Artichoke leaf appears to make the liver release more bile. This has been seen in animals and in small human studies.

More bile may help the gut cope with fatty food. That could explain reports of less bloating and fullness after meals. It is a reasonable idea, not a settled fact.

In cell and animal studies, leaf compounds also slow cholesterol production in liver cells. Whether this explains the small changes measured in people is not known.

Artichoke is widely sold as a slimming aid. There is no good human evidence that it burns fat or curbs appetite.

What forms does Alcachofa come in?

Alcachofa turns up in many shapes. What you meet depends on where you shop.

Dried leaf tea bags, sold as te de alcachofa.

Liquid drops and ampollas (small glass ampoules) mixed into water.

Capsules and tablets of dried leaf or concentrated leaf extract.

Bottled alcachofa slimming drinks and diet pills.

The vegetable itself, eaten steamed, boiled or in salads.

A warning about one form. Diet pills sold under the alcachofa name have repeatedly been found to contain hidden drugs, most often sibutramine, a weight-loss drug banned in many countries. Buy from regulated shops, not from street markets or social media sellers.

Where it comes from:

Artichoke is a Mediterranean plant. Greek and Roman writers described it as both food and a bitter tonic.

Spanish settlers carried it to the Americas. It took root in Peru, Chile, Argentina and Mexico, where it became a market crop.

Latin American home practice boiled the leaves into a tea after rich meals. Healers linked it to the liver, the gallbladder and "cleaning" the blood. From the early 1900s, European makers began selling standard leaf extracts.

What does Alcachofa help with?

• Indigestion (dyspepsia): bloating, fullness and wind: This is the use with the best support. Tradition gave bitter leaf tea after heavy or greasy food. Several small placebo-controlled trials of leaf extract reported less bloating and fullness. The trials were short and some were funded by makers. The effect looks real but modest. It is not a treatment for ulcers or reflux.
• High cholesterol (fatty substances in the blood): Reviews of leaf extract trials found a small fall in total and LDL cholesterol. Study quality was low to moderate. The average change was far smaller than that from statin drugs. It does not replace prescribed medicine. Anyone using it alongside heart care should tell their doctor and keep normal blood tests.
• Irritable bowel syndrome symptoms: Evidence here is thin. One open trial, where everyone knew what they took, reported fewer symptoms. Without a placebo group, these results are easy to overread. Treat this as unproven.
• Gallbladder and bile complaints (traditional use): Latin American and European folk use pointed the leaf at a sluggish gallbladder. Studies do show raised bile flow. More bile flow is a hazard, not a help, if a stone or blockage is present. See the safety section before considering it.
• Weight loss (traditional claim, not supported): Alcachofa is heavily marketed for slimming across Latin America. Good human trials showing fat loss do not exist. Some products work only because of hidden drugs. Several have been recalled for containing sibutramine.
• Hangover and "detox" (traditional claim, not supported): Home practice used the tea the morning after drinking. One small trial of artichoke extract for hangover found no benefit. There is no evidence it clears toxins from the body. The liver and kidneys do that work.

Which foods are rich in Alcachofa?

1. Globe artichoke hearts and bracts, the vegetable
2. Cardoon, a close relative eaten in Spain and Argentina
3. Artichoke leaf tea

Practical Tips:

Eating artichokes as food is safe for most people and gives useful fibre. The bitter leaf compounds sit mainly in the leaves, not the heart. Food amounts are far lower than extract amounts.

What are the side effects of Alcachofa?

• Wind and bloating
• Loose stools or diarrhoea
• Stomach cramps
• Feeling hungrier
• Skin rash or itching in people allergic to daisy-family plants
• Wheezing or breathing trouble, rare, in allergic people
• Pain under the right ribs if gallstones are present

Good to know:

Most side effects are mild and settle when you stop. Wind and loose stools are the most common.

Allergy is the main true risk. People who react to ragweed, chamomile, marigold or chrysanthemum can react to the leaf.

Serious harm is rare in healthy adults. The bigger danger is adulterated slimming pills sold under the alcachofa name.

How much Alcachofa should you take?

• Recommended daily: This is what labels carry, not advice for you. Capsules of artichoke leaf extract commonly list 300 mg to 640 mg, taken up to three times a day. Tea packets usually suggest one cup, one to three times a day. Trials have often used larger amounts than shop labels show. Strength differs widely between brands, so the figure on one pack does not transfer to another. A pharmacist or doctor is the right person to ask before starting, especially if you take other medicine.
• Best time of day: Timing is not critical, and no good study has tested it. For digestive complaints, products are usually taken close to meals. Tea is traditionally drunk after a heavy meal. A bitter drink late at night unsettles some people's sleep.
• With or without food: With food, or just before it, is the usual pattern. That fits the traditional idea of helping the gut handle a meal. On an empty stomach, the bitter leaf can cause cramps or loose stools in some people.
• Time to effect: Expect weeks, not hours. For indigestion, trial participants noticed change over 2 to 8 weeks. Some people report easier digestion within a few days. For cholesterol, blood tests in trials shifted after about 8 to 12 weeks. The average change was small. It may also do nothing at all. Many people feel no difference.
• How long to take it: Most trials ran 6 to 12 weeks. A few ran about 6 months. Safety past that point has not been well studied. Traditional use was short, often a few days after rich meals. If nothing has changed after about 8 weeks, there is little reason to keep going. Long-term daily use is worth raising with a doctor.
