Rosa damascena (RD) is a widely cultivated ornamental plant. It acts as an astringent, aperients, carminative, and refrigerant and is used in respiratory disorders, tonsillitis, eye disorders, migraines, gynecological disorders, and menopausal symptoms. The aim of this study is to investigate the hepatoprotective activity of the aqueous extract of RD flowers at different oral dose levels (250, 500, and 1000 mg/kg body weight) on acetaminophen (2 g/kg oral N-acetyl-p-aminophenol [APAP])-induced toxicity in rats. APAP administration altered various biochemical parameters, including serum transaminases, serum alkaline phosphatase, lactate dehydrogenase, albumin, bilirubin, urea and creatinine, hepatic lipid peroxidation, and reduced glutathione levels. Adenosine triphosphatase and glucose-6-phosphatase activity in the liver was decreased significantly in animals treated with APAP. These values are retrieved significantly by treatment with RD extract at all 3 doses in dose-dependant manner. Apart from these, histopathological changes also reveal the protective nature of the RD extract against acetaminophen-induced necrotic damage of hepatic tissues. In conclusion, these data suggest that the aqueous extract of RD may prevent hepatic damage from APAP-induced toxicity in rats and is likely to be mediated through its antioxidant activities.
