Garlic (Allium sativum) is a species in the onion genus, Allium. Its close relatives include the onion, shallot, leek, chive, and Chinese onion.
Garlic is native to Central Asia and northeastern Iran, and has long been a common seasoning worldwide, with a history of several thousand years of human consumption and use. It was known to ancient Egyptians, and has been used both as a food flavoring and as a traditional medicine.
Garlic oil is used as a nutritional supplement, and is sometimes purveyed in the form of capsules, which may be diluted with other ingredients.Some commercial preparations are produced with various levels of dilution, such as a preparation that contains 10% garlic oil.Herbal folklore holds that garlic oil has antifungal and antibiotic properties, but there is no high-quality clinical research to indicate such effects exist. It is also purveyed in health food stores as a digestive aid.
It can also be used as an insecticide, whereby it is diluted with water and sprayed on plants.
Stabilized garlic flavor blend is a proprietary mixture of dehydrated garlic powder infused with garlic oil, which increases the flavor of the garlic powder.
