Abstract

INTRODUCTION:

Many herbal medicinal products have potential hypocholesterolaemic activity and encouraging safety profiles. However, only a limited amount of clinical research exists to support their efficacy.

AIM OF THE WORK:

The present study was designed to evaluate the antihypercholesterolaemic effects of aqueous ginger (Zingiber officinale) infusion in hypercholesterolaemic rat models.

METHODS:

48 rats were used throughout the experiment, which were divided into six groups, eight animals each as follows: normal control group (normal rats which fed with standard diet). After induction of hypercholesterolaemia by feeding rats with high cholesterol diet, the remaining rats were divided into five groups: group 1, hypercholesterolaemic control group (hypercholesterolaemic rats group); groups 2, 3 and 4, rats were given aqueous infusion of ginger (100, 200 and 400 mg/kg, respectively) orally; and group 5, rats were given atorvastatin (0.18 mg/kg) orally as a reference antihypercholesterolaemic drug. The blood was obtained from all groups of rats after being lightly anaesthetized with ether and the following lipid profile [serum total cholesterol (TC), HDL-cholesterol (HDL-C), LDL-C and triglyceride levels] was measured at zero time and 2 and 4 weeks after ginger and atorvastatin treatment, and the risk ratio (TC/HDL-cholesterol) was assessed.

RESULTS:

The results revealed that the hypercholesterolaemic rats treated with aqueous ginger infusion in the three doses used after 2 and 4 weeks of treatment induce significant decrease in all lipid profile parameters which were measured and improved the risk ratio.
