'Garlic has been used medicinally by cultures around the world for thousands of years. In fact, it was used in the 1700s to ward off plague.
Garlic possesses potent antibiotic, antiviral, antifungal, and antimicrobial properties and is able to help protect and facilitate removal of unfriendly bacteria. It is also very high in natural antioxidants that destroy free radicals, which also supports a strong immune system.
The active ingredient in garlic, allicin, is the key component to killing and warding off harmful bacteria. Crush it to activate these compounds, and eat it raw, in a warm tea, or in lightly cooked food.'
