What are different types of garlic preparations?

Garlic supplements can be classified into four groups: Garlic essential oil, garlic oil macerate, garlic powder, and garlic extract.

Garlic essential oil is obtained by passing steam through garlic. Commercially available garlic oil capsules generally contain vegetable oil, but only have a small amount of garlic essential oil because of its strong odor. Garlic oil macerate products are made from encapsulated mixtures of whole garlic cloves ground into vegetable oil. Garlic powder is produced by slicing or crushing garlic cloves, then drying and grinding them into powder. Garlic powder is used as a flavoring agent for condiments and food and is thought to retain the same ingredients as raw garlic. Garlic extract is made from whole or sliced garlic cloves that are soaked in an alcohol solution (an extracting solution) for varying amounts of time.
