Understanding Garlic’s Therapeutic Properties
Active Compounds
Garlic’s medicinal properties primarily stem from allicin, its key bioactive compound. When fresh garlic is crushed or chopped, an enzyme called alliinase converts alliin to allicin, releasing the characteristic sulfur compounds responsible for both its pungent aroma and health benefits.
