The Physiological Effects of Garlic Studies by competent multi-degreed scientists have shown beyond any reasonable doubt that consuming garlic generally has the following physical effects:  Garlic lowers blood pressure a little.  Garlic lowers LDL Cholesterol a little.  Garlic helps reduce atherosclerotic buildup (plaque) within the arterial system. One recent study shows this effect to be greater in women than men.  Garlic lowers or helps to regulate blood sugar.  Garlic helps to prevent blood clots from forming, thus reducing the possibility of strokes and thromboses (It may not be good for hemophiliacs).  Garlic helps to prevent cancer, especially of the digestive system, prevents certain tumors from growing larger and reduces the size of certain tumors.  Garlic helps to remove heavy metals such as lead and mercury from the body.  Raw Garlic is a potent natural antibiotic and, while far less strong than modern antibiotics, can still kill some strains of bacteria that have become immune or resistant to modern antibiotics.  Garlic has anti-fungal and anti-viral properties.  Garlic dramatically reduces yeast infections due to Candida species.  Garlic has anti-oxidant properties and is a source of selenium.  Garlic probably has other benefits as well.
