Garlic (Allium sativum L.) has been seriously investigated in purpose to find an alternative measure for control of various diseases in humans and animals. Use in cardiovascular therapeutics has an even longer history over 3000 years to ancient time. The active chemical in garlic is allicin, which is produced when raw garlic is crushed, allowing the enzyme alliinase to act on the stable precursor alliin. Antidiabetic, antibiotic and perhaps anticancer effects of garlic are well-accepted over the world because there is a range of scientific literature to support this. Garlic also has hepatoprotective, antioxidant, and anthelmintic effect. The other pharmacological effect includes the anticoagulant, anti inflammatory, immunomodulatory and wound healing action of garlic.
