Artichoke (Cynara scolymus L., currently also classified as a synonym of Cynara cardunculus L.) is a plant from the Asteraceae family, primarily known as a vegetable in Mediterranean cuisine. It has also been used for centuries in traditional herbal medicine, particularly in the context of digestion, liver function, and proper bile flow.
Modern interest in the artichoke primarily stems from the presence of numerous bioactive compounds, including phenolic acids, flavonoids, and cynarine. Laboratory, preclinical, and some clinical studies suggest the potential antioxidant, metabolic, and hepatoprotective effects of artichoke leaf extracts. However, the strength of scientific evidence varies depending on the studied application.
Particularly interesting are studies on the effect of artichoke leaf extract on liver enzymes, lipid profile, and selected metabolic parameters. This does not mean that the artichoke is a cure for liver diseases. It is important to distinguish between the traditional use of the plant, the results of experimental research, and what has actually been confirmed in human studies.

Artichoke – what kind of plant is it?
The artichoke belongs to the Asteraceae family. Its edible part is primarily the young inflorescence, while in phytotherapy, the leaves are of particular importance.
The herbal material known as Cynarae folium includes artichoke leaves used as dried herbs, powder, and extracts. The European Medicines Agency (EMA) designates Cynara cardunculus L. as the current botanical name, with Cynara scolymus L. as a synonym.
The traditional use of artichoke leaves is mainly linked to mild digestive issues, such as a feeling of fullness, bloating, or indigestion.
Artichoke – properties and key active substances
One of the reasons scientists are interested in artichoke is its rich phytochemical profile.
Artichoke leaves contain, among others:
- cynarin,
- phenolic acids, including chlorogenic acid,
- flavonoids, such as luteolin and apigenin,
- other polyphenolic compounds,
- inulin and other fiber components,
- vitamins and minerals.
Cynarin
Cynarin is one of the most characteristic compounds associated with artichokes. Scientific literature analyzes it, among other things, in the context of lipid metabolism, bile secretion, and antioxidant properties.
However, the entire effect of artichoke should not be attributed to a single compound. The plant extract contains many substances that may work together.
Phenolic acids
Artichoke contains numerous phenolic compounds, including chlorogenic acid. These substances exhibit antioxidant activity in laboratory studies and are one of the reasons for interest in artichoke in research on metabolism and cell protection against oxidative stress.
Flavonoids
Luteolin, apigenin, and other flavonoids belong to a group of plant compounds with antioxidant and anti-inflammatory properties observed primarily in experimental studies.
Inulin and Gut Microbiota
Artichoke also contains fiber fractions, including inulin. Inulin is fermented by gut microorganisms and can serve as a substrate for selected microbiota bacteria.
This is also of interest from the perspective of the gut-liver axis, as the state of gut microbiota is closely linked to metabolism and liver function.
Artichoke for Liver – What Do Studies Say?
One of the most frequently analyzed uses of artichoke extract is its potential impact on liver health.
Experimental studies have observed, among other things, antioxidant effects and potential protection of liver cells against certain damaging factors. However, preclinical studies do not equate to confirmed therapeutic effects in humans.
Interestingly, the data from clinical studies are noteworthy. Meta-analyses of randomized studies indicate that artichoke leaf extract may affect selected parameters related to liver function, including the activity of ALT and AST enzymes. In a network analysis published in 2024, artichoke leaf extract showed beneficial potential in lowering ALT and AST in individuals with non-alcoholic fatty liver disease (NAFLD).
These results are intriguing, but they should not be interpreted as evidence that artichoke cures fatty liver. Further, well-designed clinical studies are needed to determine the optimal preparations, doses, and long-term effects.
Artichoke and Oxidative Stress
Oxidative stress is one of the mechanisms analyzed in the context of many chronic metabolic disorders and liver diseases.
Polyphenolic compounds present in artichoke exhibit antioxidant properties in laboratory and experimental studies. In animal models, changes were observed in the activity of enzymes associated with antioxidant protection.
However, it’s important to maintain a proper perspective: the antioxidant activity demonstrated in laboratory conditions does not automatically mean the same clinical effect in humans.
Artichoke and Digestion and Bile
Supporting digestion is indeed one of the most well-established traditional uses of artichoke leaves.
The European Medicines Agency recognizes artichoke preparations as traditionally used to alleviate mild digestive discomforts such as indigestion, feeling of fullness, bloating, and gas. At the same time, EMA emphasizes that available clinical studies on these uses were small and had methodological limitations, thus the recommendation is primarily based on long-term traditional use.
Therefore, the artichoke is particularly interesting for individuals seeking natural ways to support proper digestion.
Artichoke, Cholesterol, and Lipid Profile
An additional area of research is the impact of artichoke extract on lipid metabolism.
A meta-analysis of clinical studies demonstrated a link between artichoke extract supplementation and a reduction in total cholesterol, LDL cholesterol, and triglyceride levels. However, no significant impact on HDL cholesterol levels was observed.
These results suggest a potential metabolic effect of artichoke, but artichoke extract should not be considered a substitute for physician-recommended treatment of lipid disorders.
Artichoke and Liver Steatosis
Non-alcoholic fatty liver disease, now also referred to as MASLD, is strongly associated with metabolic disorders, including excessive body mass, insulin resistance, and lipid metabolism disorders.
This is why artichoke is being studied in this context. Clinical studies have analyzed its impact, among other things, on ALT, AST, and lipid parameters. The results of meta-analyses are promising, but they do not justify the claim that artichoke alone can cure liver steatosis.
In the case of MASLD, comprehensive actions concerning lifestyle, body weight, physical activity, diet, and treatment of comorbidities remain the most important.
Artichoke and Glucose Metabolism
Compounds present in artichokes are also being studied for their impact on glucose metabolism and energy management.
However, some data comes from laboratory research and animal models. Therefore, artichokes should not currently be presented as a remedy for diabetes, insulin resistance, or prediabetes.
The impact of artichokes on metabolism can be seen as an interesting direction for research, especially in combination with its potential impact on lipid profiles and liver health.
Artichoke and the Gut-Liver Axis
The scientific interest is growing in the relationship between the gut microbiota and liver function.
Artichokes contain compounds that may influence the gut environment, including fiber fractions like inulin. As a result, its potential significance may go beyond the direct effect on the digestive tract.
The concept of the gut-liver axis assumes close communication between the digestive tract, microbiota, immune system, and liver. This is currently an intensely developing area of research.
Artichoke – Leaves or Vegetable?
It is important to distinguish between artichokes consumed as a vegetable and herbal preparations containing extracts from their leaves.
In the kitchen, it is primarily the young inflorescence that is used. Herbal preparations and dietary supplements often contain concentrated leaf extracts.
Therefore, one cannot directly compare the amount of active substances delivered with a portion of the vegetable and with the dose of a standardized extract.
How to use artichoke?
The form of use depends on whether the artichoke is consumed as a vegetable or used as a preparation containing leaves or their extract.
Preparations from artichoke leaves are available, among others, as:
- dried and teas,
- powders,
- capsules,
- tablets,
- liquid extracts,
- standardized plant extracts.
There is no single universal dose suitable for all preparations because the content of active substances depends on the type of raw material, method of extraction, and standardization.
Therefore, in the case of supplements, one should follow the manufacturer’s information regarding the specific preparation, rather than just the mass of the extract stated in milligrams.
Is artichoke safe?
Artichoke is generally well-tolerated, but preparations from its leaves may cause side effects.
The EMA lists the possibility of mild diarrhea, abdominal cramps, nausea, heartburn, and allergic reactions. Artichoke leaf preparations should not be used by people allergic to plants in the Asteraceae family. They are also not intended for people with certain liver and bile duct diseases.
In the case of chronic liver disease, bile duct diseases, taking medications, or other serious health problems, it is worth consulting a doctor or pharmacist about the use of artichoke preparations.
If digestive discomfort persists for more than two weeks, the EMA recommends consulting a doctor or qualified healthcare specialist.
