Many of the claims made regarding the health benefits of garlic are linked to a compound called allicin. This sulfur-containing compound is activated when garlic is crushed or chopped and gives it its strong smell and taste.
As well as being eaten cooked or raw, garlic can be made into supplements that can be taken in the form of tablets, oils or capsules.
