Artichoke is the bud and leaf of Cynara scolymus, a tall thistle. In Italy it is called carciofo. The bud is a common vegetable, but the bitter leaf is the part used as a remedy.
Herbal products use a leaf extract, not the part you put on a plate. They are sold for indigestion, bloating and mildly raised cholesterol.
The short evidence verdict: small human trials point to modest help with indigestion and cholesterol. The trials are few, small and often of poor quality. Long use as a food and folk remedy is not proof that it works, and it is not proof that it is safe for everyone.
The main idea is that artichoke makes the liver release more bile, which helps you digest fat.
In a small human study, artichoke leaf extract raised bile flow for a few hours after a dose. That fits the old folk use for heavy, fatty meals. It does not prove the extract eases symptoms in daily life.
In cell studies, luteolin from the leaf appears to slow the making of cholesterol in liver cells. Whether this happens in people at normal doses is not settled.
In test tubes, the plant's caffeoylquinic acids act as antioxidants. Lab antioxidant activity often does not carry over to the body.
The bitter taste itself may play a part. Bitter plants have long been used to prompt appetite and digestion, but this is tradition, not proven effect.
Most medicinal products are dried leaf extract in a capsule or tablet.
Other forms you may see:
Standardised extracts, often listed by cynarin or caffeoylquinic acid content.
Liquid tinctures and pressed leaf juice.
Teas made from dried leaf, which taste strongly bitter.
Bitter aperitif drinks, such as Cynar, which contain alcohol.
The vegetable itself, eaten fresh, tinned or in oil.
Food and medicine are not the same here. A plate of artichoke hearts gives far less of the bitter leaf compounds than a capsule.
Artichoke was grown around the Mediterranean for food and medicine for well over two thousand years.
Greek and Roman writers described it as a food that stirred the appetite. Later European herbals listed the leaf for liver complaints, jaundice and sluggish digestion.
French and Italian folk practice used bitter leaf teas after rich meals. In the twentieth century, European makers turned the leaf into standardised extracts, and German herbal authorities reviewed it for digestive complaints.
These records describe what people did. They do not show that the remedy worked.
Stop and get medical help the same day if you get sharp pain under your right ribs, pain spreading to your shoulder blade, or fever with sickness. These can mean a gallstone has moved.
Go to an emergency department if your skin or eyes turn yellow, or if your stools go pale and your urine goes dark.
Get urgent help for signs of a serious allergy: swelling of the lips or tongue, a spreading rash, or trouble breathing.
See your doctor if indigestion lasts more than two weeks, if you are losing weight without trying, or if you vomit blood or see black stools.
In the UK, the EU and the US, artichoke is an ordinary food. Leaf extracts are sold as food supplements, not as licensed medicines.
Supplements are not checked for strength or purity the way medicines are.
