Ginger is an important medicinal herb has numerous bioactive components and is used in the management, control and/or treatment of diseases including diabetes mellitus. The present study was undertaken to see the dose-response effect of ginger and evaluate the possible protective effects of dietary ginger on oxidative stress and genotoxicity induced by streptozotocin (STZ) diabetic rats. Inbred male Wistar/NIN rats of 8-9 weeks old were treated with 30 mg/kg of STZ. Rats were divided into different groups of control, diabetic non-treated, and diabetic treated with ginger powder at 0.5%, 1% and 5% respectively. After feeding for a month, blood and tissues were collected to see the effect of ginger on antioxidant status, DNA damage and bone marrow genotoxicity. In this study ginger exerted a protective effect against STZ-induced diabetes by modulating antioxidant enzymes and glutathione and down regulating lipid and protein oxidation and inhibition in genotoxicity in a dose-response manner.
