The present study investigates the antihyperlipidemic and hepatoprotective potential of the ethanolic extract of Cissus quadrangularis (EECQ) in Wistar albino rats. Dried and powdered plant material was subjected to Soxhlet extraction with ethanol, yielding a semi-solid green extract. Hyperlipidemia was induced in male Wistar rats (200–250 g) using a high-fat emulsion. The animals were divided into groups and treated with either a standard drug (Rosuvastatin, 10 mg/kg) or EECQ at low and high doses. Biochemical parameters, including lipid profile, liver function tests, and oxidative stress markers, were assessed. The study demonstrated that high-fat diet-induced hyperlipidemia caused significant disturbances in lipid metabolism, liver function, and oxidative stress. Treatment with EECQ produced dose-dependent improvements, with the high dose showing significant reductions in total cholesterol, triglycerides, LDL levels, and oxidative stress markers, along with an increase in HDL levels. Histopathological analysis further supported the protective effects of the extract. These findings suggest that EECQ holds therapeutic potential as a natural alternative for the management of hyperlipidemia and associated hepatic dysfunction.
Obesity is a complex disease characterized by having an excessive amount of body fat, which poses serious health risks. It is not merely a cosmetic issue but a medical problem associated with various diseases like heart disease, diabetes, high blood pressure, high cholesterol, liver disease, sleep apnea, and certain cancers.
Obesity has become the number one public health threat in the twenty-first century, replacing malnutrition in the twentieth century. Its prevalence has dramatically risen over the past few decades in most developed countries. It has become a significant burden for the health economy. Whilst the changing lifestyle, the obesogenic environment has a significant influence on the increasingly higher incidence of obesity; there are several genetic risk factors such as gene variants, genetic syndromes, and single gene mutations, which make it very difficult to control obesity.
Obesity can lead to numerous health complications including:

CONCLUSION:
The present study demonstrates that induction of hyperlipidemia leads to significant alterations in lipid metabolism, liver function, and oxidative stress parameters, confirming its detrimental effect on hepatic and cardiovascular health. Treatment with the standard drug successfully normalized these biochemical and histopathological changes, validating its efficacy. Importantly, the ethanolic extract of Clerodendrum quadriloculare (EECQ) exhibited dose-dependent antihyperlipidemic and hepatoprotective effects. While the lower dose produced moderate improvements, the higher dose showed significant reductions in cholesterol, triglycerides, LDL, and oxidative stress markers, along with an increase in HDL levels. These findings suggest that EECQ possesses promising therapeutic potential as a natural alternative for the management of hyperlipidemia and its associated complications.
