The root bulb of garlic plant is used for medicinal purpose. Medicinally used garlic oil consists of diallyl (57%), allyl methyl (37%) & dimethyl (6%) mono to hexa sulphides (Koch et al, 1996).19 Many randomized clinical trials have studied the effect of garlic on lipid levels. Results from two Meta analysis conducted in 1993 by Warshafsky et al20 and in 1994 by Silagy et al21 on the effect of garlic on total cholesterol show a significant reduction in total cholesterol level (9-12% when compared with placebo). A more recent trial by Ackerman et al in 2001 is a placebo controlled trial using standardized dried garlic powder which shows significant reduction in total cholesterol levels (19.2mg/dl), LDL level (6.7mg/dl) triglyceride level (21.1mg/dl) in 8-12 weeks.22
