The purpose of the present study was to investigate the lipid lowering effect of Cinnamomum zeylanicum (Cinnamon) in hyperlipidaemic albino rabbits. For this purpose, forty eight albino rabbits were randomly divided into eight equal groups; untreated control on normal routine feed, untreated control on butter and cholesterol, treated control on synthetic cholesterol lowering drug simvastatin (Tablet survive (R) 20 mg), three treated groups on three respective doses of C. zeylanicum bark powder and two treated groups on water and methanol extracts of C. zeylanicum bark powder. Butter ad lib and cholesterol powder 500 mg/kg body weight were used to induce experimental hyperlipidaemia in all groups except untreated control group. The results suggested that C. zeylanicum bark powder at the rate of 0.50 g/kg, 0.75 g/kg and methanol extract equivalent to 0.75 g/kg powder produced respective percent reductions in total lipids by 45, 49 and 64; triglycerides by 38, 53 and 60; total cholesterol by 53, 64 and 69 and LDL-cholesterol by 50, 59 and 62. However, at these dosage levels HDL-cholesterol showed respective percent increase of 42, 48 and 53. Nonetheless, C. zeylanicum bark powder at the level of 0.25g/kg and C. zeylanicum extract in water could not significantly reduce lipid profile indicators. Based on these studies, it can safely be said that C. zeylanicum bark powder methanol extract equivalent to 0.75g/kg bark powder and simvastatin (0.6 mg/kg b. wt.) were equieffective in treating hyperlipidaemia.
