Abstract
Allium sativum commonly referred to as garlic has been known over the years for its medicinal and culinary purposes. It has also been reported to have several toxic effects when used excessively. However, the purpose of this study was to determine the histological effects of Allium sativum (garlic) powder on the liver of white rabbits at different dosages. Twenty rabbits were randomly divided int.o five groups with free access to food and water for a period of four weeks. Four groups B, C, D, and E were fed with garlic supplemented basal diet containing different concentrations of garlic powder i.e. 100mg, 200mg, 500mg, and 1000mg respectively. These groups were called the treated group. Group A was fed with basal diet only and was considered as the control group. The results obtained showed some histological changes such as the presence of cellular necrosis, vacuolations, lipofuscin pigments, pyknosis and nuclear hypertrophy which were as a result of liver glycogen depletion and hepatic cell damage which may be due to relatively high dosage of garlic used in some of the groups.
