To substantiate the present finding, a parallel administration of metformin was done in three different doses to another group of 12 rabbits. Six of them were normal and six were rendered diabetic. All normal rabbits showed a duly expected hypoglycemic and hypolipidaemic response to garlic extract as well as to metformin. In a number of studies, garlic has been found to be effective in lowering serum glucose level in STZ- -induced as well as alloxan induced diabetic rats and mice and rabbits. Garlic is also said to lower serum cholesterol [4].
