What is Garlic Used for?

There are a number of different Garlic preparations available, and different preparations will yield different chemical properties. Dried Powdered Garlic, if prepared properly contains S-allylcysteine sulphoxide (alliin) and the enzyme alliinase. A majority of the published clinical studies used garlic powder preparations. Aged Garlic extracts or “odorless” Garlic are produced through fermentation and contain sulphur compounds. Steam Distillation of Garlic yields Garlic Oil which is rich in diallyl sulphides. In addition to these preparations, fresh Garlic should also be considered as it is the most chemically complex form of this medicinal herb. Dr. James Dukes Ethno botanical database lists over 170 non ubiquitous chemicals in garlic bulb. Many studies have been conducted on Garlic's potential to support heart health and normal blood lipids. It also appears to be beneficial for supporting immune health.
