Garlic has a protective effect on your kidneys and other organs. Regular consumption has been found to lower the concentration of lead and cadmium in kidneys, heart, liver, spleen, and blood stream. Garlic also has diuretic properties that help you eliminate excess sodium from your body.
And not only that, but allicin, the active ingredient in garlic, has anti-inflammatory, antibacterial, and anti-fungal properties. That means it can greatly assist your kidneys in cleansing and filtering blood of harmful invaders.
