Garlic Provides strong antioxidant action to protect cell membranes against free-radical formation. Some studies show that even low doses, garlic stimulates the immune system, increasing the activity of natural “killer cells” to ward off pathogens.
Garlic also has strong antibiotic properties. It kills intestinal parasites and worms, as well as gram-negative bacteria. In recent studies, researchers using fresh and powdered garlic solutions discovered that garlic inhibited many bacteria, including Staphylococcus auras, E. coli, Proteus vulgarism, Salmonella enteritidis, Klebsiella pneumonia and many others.
When compared to antibiotics such as penicillin, tetracycline, erythromycin, and others prescribed, garlic proved to be as effective. One medium-size garlic clove delivers the antibacterial equivalent of about 100,000 units of penicillin (typical oral penicillin doses range from 600,000 units to 900,000 units). Therefore a dose of 6 to 9 garlic cloves has roughly the same effect as a shot of penicillin.
