Nonalcoholic fatty liver disease (NAFLD) is a major chronic liver disease that can lead to liver cirrhosis, liver cancer, and death. Artichoke leaf extract (ALE) is well known in folk medicine for its hepatoprotective effect. Till recent times, no sufficient data from randomized clinical trials (RCTs) exist to support such use. This meta-analysis summarizes evidence from recent RCTs that evaluated ALE in NAFLD patients. Electronic databases were searched for RCTs that used ALE in NAFLD patients. The random-effects model was used to pool effect sizes (standardized change score). Data synthesis from five RCTs (333 patients) showed that ALE resulted in a significant reduction in alanine aminotransferase (standardized mean difference [SMD]: 1.1; 95% confidence interval [CI], 0.79-1.73; P P P = .004), low-density lipoprotein (SMD: 0.96; 95% CI, 0.3-1.62; P P ( https://www.crd.york.ac.uk/prospero).
Artichoke (Cynara scolymus) leaf extract was one of the few herbal remedies which the clinical and experimental trials have complemented each other. Both experimental and clinical effects have been verified through extensive biomedical herbal remedy research. Specifically, antioxidant, choleretic, hepatoprotective, bile-enhancing and lipid-lowering effects have been demonstrated, which corresponded with its historical use. Ongoing research seems to indicate that artichoke indeed have medicinal qualities. Most significant appears to be its beneficial effect on the liver. In animal studies, liquid extracts of the roots and leaves of artichoke have demonstrated an ability to protect the liver, with possibly even to help liver cells regenerate. Although research is not yet conclusive, scientists were optimistic that its long-standing use in humans for digestive and bowel problems was indeed justified. It may also play a role in lowering cholesterol and thus help to prevent heart disease. Boiled wild artichoke reduced postprandial glycemic and insulinemic responses in normal subjects but has no effect on metabolic syndrome patients. This article intended to review the wide ranging pharmacological effects of artichoke leaf extract.

Mechanistic basis
This use is associated with the plant's choleretic / cholagogue (bile flow), hepatoprotective (liver support) actions. Further evidence for that pharmacology:
Dietary supplements enriched with bioactive compounds represent a promising approach to influence physiological processes and enhance longevity and overall health. Cynara cardunculus var. scolymus serves as a functional food supplement with a high concentration of bioactive compounds, which offers various health-promoting benefits. Several chronic diseases have metabolic, genetic, or inflammatory origins, which are frequently interconnected. Pharmacological treatments, although effective, often result in undesirable side effects. In this context, preventive approaches are gaining increased attention. Recent literature indicates that the consumption of bioactive compounds in the diet can positively influence the organism's biological functions. Polyphenols, well-known for their health benefits, are widely recognized as valuable compounds in preventing/combating various pathologies related to lifestyle, metabolism, and aging. The C. scolymus belonging to the Asteraceae family, is widely used in the food and herbal medicine fields for its beneficial properties. Although the inflorescences (capitula) of the artichoke are used for food and culinary purposes, preparations based on artichoke leaves can be used as an active ingredient in herbal medicines. Cynara scolymus shows potential benefits in different domains. Its nutritional value and health benefits make it a promising candidate for improving overall well-being. C. scolymus exhibits anti-inflammatory, antioxidant, liver-protective, bile-expelling, antimicrobial, and lipid-lowering neuroprotective properties. Different studies demonstrate that oxidative stress is the leading cause of the onset and progression of major human health disorders such as cardiovascular, neurological, metabolic, and cancer diseases. The large amount of polyphenol found in C. scolymus has an antioxidant activity, enabling it to neutralize free radicals, preventing cellular damage. This reduces the subsequent risk of developing conditions such as cancer, diabetes, and cardiovascular diseases. Additionally, these polyphenols demonstrate anti-inflammatory activity, which is closely associated with their antioxidant properties. As a result, C. scolymus has the potential to contribute to the treatment of chronic diseases, including intestinal disorders, cardiovascular diseases, and neurodegenerative pathologies. The current review discussed the nutritional profiles, potential benefits, and pharmacological effects of C. scolymus.
Current evidence has shown antioxidant activity of artichoke as a potent source of antioxidant compounds. However, it seems that the antioxidant activity of artichoke has not yet been reviewed. Therefore, the present study was designed to perform a systematic review of human studies, animal models, and in vitro systems and to conduct a meta-analysis of animal studies on the antioxidant effects of artichoke. We searched four electronic databases till April 2018 using relevant keywords. All English language articles were assessed. For animal studies, standardized mean difference was pooled using a random effects model. The included studies were evaluated for eligibility and risk of bias. Thirty-nine articles (two human, 23 animal, and 14 in vitro studies) were reviewed. The results of in vitro systems supported the antioxidant effect of artichoke, whereas limited clinical trials indicated no change or a slight improvement of antioxidant status. Finding of animal studies indicated that artichoke extract supplementation increased superoxide dismutase, catalase, glutathione, and glutathione peroxidase level in liver, as well as, decreased malondialdehyde level in liver and plasma of animals with induced disease significantly compared with comparison group. This meta-analysis provided convincing evidence for antioxidant activity of artichoke in animals.
Background Diazinon (DZN) causes serious liver damage in both humans and animals. In the present study, the hepatoprotective effects of Cynara scolymus L. leaf extract against DZN-induced liver injury were examined. Methods Forty male rats were divided into five groups. The control group received a normal diet. The DZN group received DZN only (25 mg/kg, po). The DZN + Syl group received DZN (25 mg/kg, po) and silymarin (Syl) (50 mg/kg, po). The DZN + Art group received DZN (25 mg/kg, po) and artichoke (Art) leaf extract (1500 mg/kg, po). The Art group received Art leaf extract only (1500 mg/kg, po). After 15 days, serum tumor necrosis factor α (TNF-α), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), lipid profile, protein carbonyl content, serum and hepatic malondialdehyde (MDA), hepatic TNF-α gene expression, hepatic catalase (CAT), superoxide dismutase (SOD), and vitamin C (Vit C) were measured and histopathological examination was performed. Results DZN caused a significant elevation in serum ALP, AST, ALT, MDA, TNF-α, protein carbonyl, hepatic MDA, and TNF-α gene expression in the DZN group as opposed to the control group. Also, DZN led to the reduction of hepatic CAT, SOD, and Vit C in the DZN group relative to the control group. The administration of Art extract resulted in not only a significant reduction in serum ALP, AST, ALT, MDA, TNF-α, and protein carbonyl but also an improvement of liver histopathological changes and hepatic CAT and SOD activities as opposed to the DZN group. Conclusions This study confirmed that Art leaf extract has liver protective effects and causes downregulation of oxidative stress in acute DZN-induced liver injury in rats.
