Background/Objective: Cardiometabolic syndrome (CMS) is a complex clinical condition that encompasses metabolic dysregulation, cardiovascular disease, and diabetes risk factors. Worldwide, CMS is underdiagnosed, and its occurrence significantly increases cardiovascular morbimortality. Despite available pharmacological treatments, the approach is fragmented, and the associated clinical conditions are treated independently. This approach may be partially due to limited preclinical models to mimic the clinical conditions of CMS. Therefore, our study aims to present an innovative animal model of cardiometabolic syndrome and evaluate the effects of Baccharis dracunculifolia on the set of clinical alterations associated with the condition. Methods: Female Wistar rats were induced to develop diabetes, fed a cholesterol-enriched diet, and exposed to the smoke of 9 cigarettes/day for 6 weeks. During the last 2 weeks, the rats were treated with vehicle, B. dracunculifolia (30, 100, and 300 mg/kg), or a combination of simvastatin and insulin. At the end of the treatment, plasma lipid levels were measured, and the liver was analyzed histologically for hepatic lipid quantification and oxidative stress assessment. Results: Phytochemical analysis revealed seven phenolic acids and six flavonoids in the extract. B. dracunculifolia showed significant hepatoprotective effects, reducing AST and ALT levels and lowering both plasma and hepatic lipid levels. The extract also reversed hepatic steatosis and demonstrated antioxidant properties. Conclusions: These findings suggest that B. dracunculifolia may be a therapeutic option for the metabolic dysregulation present in CMS.

Metabolic‐associated fatty liver disease (MAFLD) is a complex condition characterized by steatosis and metabolic disturbances. Risk factors such as diabetes, cigarette smoking, and dyslipidaemia contribute to its development and progression. Effective and safe therapies for MAFLD are urgently needed. Pereskia grandifolia has shown potential as an alternative treatment, but its effectiveness against liver disease remains unexplored. This research aims to determine the hepatoprotective properties of P. grandifolia using a model of MAFLD. The study was carried out through various phases to assess the safety and efficacy of the ethanol‐soluble fraction of P. grandifolia. Initially, an in vitro assay was performed to assess cell viability. This was followed by an acute toxicity test conducted in rats to determine the safety profile of the extract. Subsequently, the anti‐inflammatory properties of P. grandifolia were examined in macrophages. For the MAFLD study, diabetic Wistar rats were made diabetic and exposed to a high fat diet and cigarette smoke, for 4 weeks. During the last 2 weeks, the rats were orally given either the vehicle (negative control group; C‐), P. grandifolia (30, 100, and 300 mg/kg), or insulin in addition to simvastatin. A basal group of rats not exposed to these risk factors was also assessed. Blood samples were collected to measure cholesterol, triglycerides, glucose, ALT, and AST levels. Liver was assessed for lipid and oxidative markers, and liver histopathology was examined. P. grandifolia showed no signs of toxicity. It demonstrated anti‐inflammatory effects by inhibiting phagocytosis and macrophage spreading. The MAFLD model induced liver abnormalities, including increased AST, ALT, disrupted lipid profile, oxidative stress, and significant hepatic damage. However, P. grandifolia effectively reversed these changes, highlighting its potential as a therapeutic agent. These findings emphasize the significance of P. grandifolia in mitigating hepatic consequences associated with various risk factors.
